Second cropping potatoes – Invest in breathable storage to stop second cropping potatoes from rotting Image: Potato Sacks (paper) from Thompson & Morgan In the UK, second cropping potatoes are best planted outdoors in early August and no later than the end of August. If planting in a protected environment like a polytunnel or greenhouse, you can delay planting by a week or so but, to avoid disappointing results, you must have done it by the end of the first week of September.
- There is no need to pre-chit these seed potatoes as this happens quite naturally after planting.
- ‘Ping-pong ball’ sized tubers should be ready for harvesting approximately 10 to 11 weeks after planting.
- Cut back the stems to just above ground level and dig up your spuds as you need them.
- Protect late crops from frost by covering them with a thick layer of straw and/or sacking, and although they’ll be more susceptible to attack by slugs and wireworm, you should be able to continue harvesting until around Christmas time.
After harvesting, leave the tubers on the soil surface for a few hours to dry and cure the skin. Once dry, store them in paper sacks in a dark, cool but frost free place. Avoid storing in polythene bags as potatoes will ‘sweat’ and rot. Now you know how to plant and grow your own potatoes, all you need to do is decide which varieties to go for.

Is July too late to plant potatoes UK?
Planting time for potatoes does vary depending on the type of potato you are growing and also the part of the UK you are in. Generally, the time at which all potatoes are ready to plant is when the last frosts of winter have passed which could be sooner or later depending on which part of the country you are in.
First earlies – planted late March to early AprilSecond earlies – planted early-ish April to the middle of AprilMaincrops – planted the middle to late April
Give or take a few weeks on these depending on local conditions. If growing in greenhouses you can obviously plant earlier even in cooler parts of the country. Likewise, if growing in containers, these can be moved and kept in warmer areas while you’re waiting for outside conditions to reach optimum levels.
What is the latest I can plant potatoes?
When to plant potatoes – As with knowing when to plant vegetables in general, when you plant potatoes will depend on your climate, soil conditions and the estimated date of the last frosts in your area. Potatoes are not hardy plants, so in general they are planted in spring from mid March to late April and can be harvested anywhere between June and October.
In milder regions potatoes may be planted earlier than in colder regions. ‘In general, potato plants are usually planted two to three weeks before the last frost date,’ says gardening expert Mary Jane Duford, known for her step-by-step guides. ‘The plants take about two to three weeks to sprout up above the soil, meaning that the timing works out so that potato plants sprout outdoors around the time of the local last frost date.’ Before planting potatoes you can give them a head start by ‘chitting’ them.
This is a process which encourages seed potatoes to develop shoots before they are planted. To do this lay the seed potatoes in trays (you could use egg boxes) with their eyes pointing upwards and place the trays in a cool, light, frost-free place. In northern latitudes chitting is generally done six weeks before planting. (Image credit: Getty Images)

Typically, potatoes are planted in March for harvesting throughout the summer and autumn months. But they can also be planted in August or September so that you can enjoy new potatoes around Christmas. But before you can plant your potatoes, the seed potatoes themselves need to be chitted.
How late can you plant main crop potatoes UK?
Your guide to potato season Knowing which to choose, and when to plant them, makes all the difference when it comes to harvesting a bumper crop of homegrown spuds. From first earlies through to late season potatoes, this guide explains how and when to plant all your favourite varieties, along with some top tips to help you get the best from your crop.
Potatoes are a staple food for two thirds of the world’s population and the leading non-grain food crop. In the UK alone, we produce over 6 million tonnes of potatoes each year involving more than 3,400 commercial growers. They’re very healthy too. In fact, as a source of carbohydrates, they’re far more nutritious than most of the alternatives.
Here are a few nutritional facts:
Boiled potatoes have the second highest concentration of folic acid after bread. Baked in its skin, an average sized spud contains over 30% of the Recommended Daily Allowance. Potatoes contain no cholesterol. Potatoes provide approximately 15% of Britain’s Vitamin C intake. Rice and pasta provide none whatsoever. Potatoes are 72-75% water, 16-20% carbohydrate, 2-2.5% protein, 0.15% fatty acids, 1-1.8% dietary fibre. Potatoes actually top bananas in potassium content: a medium banana contains roughly 450mg, while a medium baked potato or 20 French fries contains 750mg. One medium potato supplies, on average, 30mg vitamin C, nearly as much as in a glass of tomato juice and 1.5mg iron, which is around the same amount as in an egg.
One of the reasons potatoes are such a popular global crop is because they’re so easy to grow. As a home grower, you’ll be pleased to know they’ll flourish in the ground, in raised beds, or in containers – people even grow potatoes inside old car tyres. As a cheap and very tasty source of carbs, vitamins and minerals, the humble spud is hard to beat. Growing your own potatoes allows you to try flavoursome varieties like ‘Casablanca’ Image: from Suttons There are four main varieties of potatoes which we grow here in the UK: first and second earlies; maincrop; and late season or second-cropping potatoes.
- As the names suggest, each has a slightly different growing season.
- First early varieties can be planted from February, while second croppers don’t go into the ground until about July.
- Deciding which type to go for depends on what kind of potatoes you like to eat and the prevailing weather conditions where you live.
If you like new potatoes, opt for first and second earlies. Lovers of a hearty roast potato should go for maincrop varieties, and if you want to feast on hot buttery spuds all winter long, you’ll be looking to get second croppers into the ground between June and late July.
That said, if you live in one of the warmer, wetter parts of the country, early varieties will probably work best for you. Blight is the potato’s nemesis – it thrives when the night time temperature rises above 10C and when warmer weather combines with lots of humidity. Blight can strike at any time, and can decimate a crop in days.
The earlier you get your potatoes in the ground and harvested, the better chance you’ll avoid it. ‘Rocket’ is a very early, heavy-cropping new potatoImage: from Suttons like and ‘’ are commonly called ‘new’ potatoes and produce their harvest in June and July. You should be booking to get your chitted seed potatoes into the ground sometime between February and April, depending on the weather and when you want to harvest.
Taking just 9-13 weeks to grow, first early potatoes produce tasty tubers that have a white waxy flesh. They’re typically smaller potatoes and you should boil, steam or sauté them fresh from the ground – the flesh retains more of its natural sugars this way, tasting even sweeter and more delicious. Plant first early potatoes to a depth of 10cm with at least 25-30cm between each potato, leaving 45cm between rows to give your plants enough room to grow and expand.
Nine to 12 weeks later, you’ll notice flowers beginning to bloom. This indicates that the tubers have set and you can commence cropping. Dig a couple of plants to check on progress and then harvest as and when you fancy hot, buttered new potatoes for lunch or dinner. ‘Kestrel’ is a good variety for the show benchImage: from Suttons like ‘’ and are also classed as ‘new’ potatoes and only take a few weeks longer to mature than first earlies. Plant second earlies between March and April and aim to harvest 14-16 weeks later, in June through to September.
‘Charlotte’ is one of the most popular salad potato choicesImage: from Suttons are typically second early potatoes. They are planted between March and early May at a depth of 10cm with 30cm between each potato. There needs to be at least 45cm between each row to give the potato plants enough room to grow.
‘Desiree’ is a versatile red maincrop potato that is a great all-rounderImage: from Suttons take longer to grow than first early and second early potatoes. Planted between March and early May, stalwart maincrop varieties like take 16-22 weeks to mature and are ready for harvesting between the end of August and October.
If you’re happy to wait for big yields of delicious homegrown potatoes, maincrops are for you. Maincrop potatoes produce tubers that are extremely versatile. They taste delicious mashed, boiled, steamed, roasted and baked, and are also great for making chips. Plant main crop potatoes to a depth of 10cm with 40cm between each potato, leaving at least 70 to 75 cm between each row to give them plenty of space to grow.
Open flowers (if present) indicate when the first tubers appear. This should occur around 14 weeks after planting. The potatoes should then be left for 4 to 8 weeks to allow the skin to harden so that they are able to store better. ‘Nicola’ is a popular, smooth-skinned yellow potato with a great flavourImage: like and Nicola are commonly known as second-cropping potatoes and are grown for winter consumption. If you choose to grow these late season potatoes, you’ll be able to enjoy them from October all the way to Christmas Day! Late season potatoes are grown from tubers that have been stored in a temperature controlled room, keeping them dormant until they’re ready to be planted between June and late July.
- Plant these seed potatoes as soon as they arrive so they can benefit from the warm summer soil where they’ll grow rapidly.
- Follow the same planting instructions as main crop potatoes and you’ll be ready to harvest in October.
- Fancy freshly-harvested, buttery new potatoes with cold ham or turkey at your Christmas buffet? Simply leave some of your late crop in the ground until the big day.
We hope we’ve given you plenty of advice to help you choose the best potatoes for your needs.

What potatoes can I plant in August UK?
Use cold-stored potato tubers, available from specialist seed merchants in July and August. These are seed potatoes from late winter that have been held back ready for summer planting. First and second early varieties such as ‘Charlotte’, ‘Nicola’ and ‘Maris Peer’ are recommended.
- As these will go straight into warm soil, they do not need to be chitted prior to planting.
- You can hold back late-winter-bought tubers yourself by keeping them in the fridge or leaving them in a cool, light place right through the spring and early summer and allowing them to develop long (and rather fragile) sprouts.
These will need to checked regularly for aphids, Potatoes harvested in summer and then replanted will not produce tubers for winter as they go through a long period of dormancy after harvest.
What can I plant after potatoes in August UK?
Crop rotation for potatoes: what to plant after potatoes – Potatoes are fantastic at preparing soil for other plants. They are particularly important for heavy soils, as their large root system loosens the earth. Once harvested, potatoes can be replaced with medium-hardy root crops, such as carrot ( Daucus carota ), parsnip ( Pastinaca sativa ), salsify ( Scorzonera hispanica ), beetroot ( Beta vulgaris ) and turnip ( Brassica napus subsp.
rapifera ). A year after your potato harvest, plant low-yielding, leafy vegetables, such as lettuce, radish ( Raphanus sativus ), pea ( Pisum sativum ) and spinach. Followed by green manure the year after, which will replenish organic matter in the soil and rebuild humus. Green manure also provides food for insects, and covers the soil, preventing the earth from drying and eroding.
Radish ( Raphanus sativus ), mustard ( Sinapis alba ), lacy phacelia ( Phacelia tanacetifolia ) and cress ( Lepidium sativum ) are just a few examples of green manure plants. Once you have found an ideal location to cultivate your potatoes, it can be difficult to sacrifice it.
Can you grow potatoes in June UK?
But as a general guide: First early varieties should be ready to lift in June and July. Second earlies in July and August. Maincrop varieties from late August through to October.
Can I leave potatoes in the ground over winter?
The Short Answer – The gardener’s goal is to dig every potato out of the ground at harvest time, Missing a few potatoes is easy to do, and the tubers will overwinter in the soil. If you live in a climate where the soil freezes deeply, these forgotten potatoes will freeze and turn to mush.
How long do potatoes take to grow?
Planting, Growing and Harvesting Potatoes Potatoes top the list for vegetables to grow at home. Homegrown potatoes taste a world better than store-bought, they’re easy to grow, and they’re especially fun to harvest — like digging for treasure! Shutterstock/Olga Bondas When you grow your own potatoes, you can try a wealth of colors, sizes and types that aren’t readily available at grocery stores.
Another reason to grow your own potatoes? Variety. Potatoes are cultivated and eaten all over the world, and there are more than 5,000 varieties and counting. Even the best gourmet grocery is only going to offer a handful of those options, but you can grow whatever you can find. Potatoes come in a rainbow of colors and can be white, yellow, blue, purple, pink or red.
While potatoes ( Solanum tuberosum ) are often called “Irish” potatoes to distinguish them from sweet potatoes ( Ipomoea batatas ) or yams ( Dioscorea spp.), which are different plant species altogether, these tasty tubers actually originated in the Andean highlands of South America, not in Ireland (or in Idaho, for that matter).
- Potatoes are in the Solanaceae or Nightshade family of plants that also includes tomatoes, peppers and eggplants.
- Potatoes were brought to Europe by Spanish conquistadors in the early 1500s, introduced to Britain and Ireland soon after, and then crossed the Atlantic again to arrive in North America in the early 1700s.
While potatoes are very popular now — it’s estimated that Americans eat one a day — they were a tough sell for many people when first brought to Europe. Potatoes are planted in spring in all areas, and again in fall in mild climates, from small pieces of mature tubers, called “seed” potatoes, each with one or two buds.
Buy seed potatoes from certified sources; many online seed companies also sell seed potatoes. Plant as soon as soil can be dug in early spring ; if the weather then is typically rainy, plan ahead by working up rows or hills in the fall. In freeze-free areas of the country, including the Southwest and along the Gulf Coast, potatoes can be planted in the fall or winter ; however, it is usually difficult to find seed potatoes then, so they must be ordered and stored ahead of time.
Shutterstock/Viktor Sergeevich Seed potatoes can be planted whole, or they can be cut into sections, each containing at least one eye (also called a sprout), before planting. Can you plant grocery store potatoes? While you can try planting from grocery store potatoes, these commercial potatoes may have been sprayed with chemicals to keep them from sprouting in storage, so growth may be stunted and your yields lower or dismal.
- Trust us: It’s best to use seed potatoes.
- Potatoes require cool weather — not freezing, not hot — to survive and produce edible underground tubers.
- While healthy potato plants can tolerate light frosts, and may even recover from mild freeze damage, they cannot survive hard freezes.
- Plant potatoes after the danger of freezing is past, a few weeks before the last frost date, but well before hot weather sets in for the summer.
Cut seed pieces two or three days ahead of time to allow cut surfaces to heal, which reduces rotting when they are planted in cold, wet soils. The pieces may also be allowed to sprout or “chit” several weeks before planting, which can be helpful in areas where the growing season is cold and short.
Sow seed potatoes, “eyes” (sprouts) up, two to three inches deep and about a foot apart. For traditional row plantings, keep rows three to four feet apart. Dig your planting furrow up to six inches deep, keeping extra soil from the furrow stacked alongside the planted row to use for hilling. In beds using intensive planting methods, such as wooden raised beds, sow potatoes 12 inches apart in staggered rows. In containers, you can plant potatoes more closely and your yield will just be smaller.
Shutterstock/Dina V A gardener cares for a large patch of potatoes, planted in deeply furrowed rows. Planting in furrows allows for hilling around the tubers as they form. In addition to cool weather, potatoes require at least 6 hours of sun, very well-drained soil, regular water and moderate fertilizer.
For clay soils, add compost to improve drainage and prevent waterlogged soils, which rot potatoes. Heaviest tuber formation occurs when soil temperatures are in the 60-70 degree range, and stops when soil temperatures reach 80 degrees or so. Mulching soil with straw or other organic matter can help reduce soil temperature by as much as 10 degrees.
Water more often if growing in containers as they tend to dry out more quickly. Once the seed potatoes are planted, they sprout quickly into lush, leafy, multiple-stem plants. As the plants grow, new tubers begin to form on short stolons that grow downward into the ground.
Start hilling potatoes when stems reach six to eight inches tall. Hill potatoes every week or two until the plants have at least six inches of lower stem buried. Gather soil around stems, covering roughly 1/2 to 2/3 of the exposed stem and leaves. Most gardeners make one to two hillings, but you can continue to hill plants throughout the entire growing season. To have enough soil on hand for hilling, remove the top 12 inches of soil prior to planting and stash it nearby. You can also hill using a blend of homegrown compost and bagged potting soil or topsoil. Or, save soil from container gardens at the end of the growing season to blend with compost for this purpose. Simplify the hilling process by substituting straw for soil. Add straw frequently to maintain consistent levels. With this method, harvesting is a cinch — no digging is required. Simply pull straw away to reveal tubers. Whether you use soil or straw, it’s vital to keep potato roots moist from the time plants flower until roughly two weeks before harvest. Potatoes have shallow roots and are sensitive to fluctuating soil moisture. When you’re hilling with soil, it’s a good idea to add a mulch layer. Mulch reduces evaporation and maintains lower soil temperature.
Potatoes will grow in all kinds of containers, from terra cotta pots to whiskey barrels or galvanized bins. makes harvesting simple — just dump out the contents to find your prize potatoes. You can also try special potato grow bags; some make harvesting easier with a lift-up flap that reveals the tubers growing beneath the soil.
These are an excellent option for small-space or patio gardens. Depending on variety and local weather, the potato growing season is about three or four months from planting to digging, with some early varieties and immature or “new” potatoes harvested a little earlier. Most gardeners plant in March, April or May, and expect a harvest about four months later, starting to dig new potatoes about two to three weeks after plants flower.
Harvest “new” potatoes — any potato harvested while small before their sugars have fully converted to starch — a couple months after planting by pulling a plant or two, or by feeling around in soil or straw and pulling a few young spuds. When plant tops start to die back, you’ll know it’s time for the main harvest,
Don’t wash newly dug potatoes. Instead, give them a simple brush with gloved hands. Freshly harvested potatoes need time to cure and form dried skins before storing. Cure potatoes by arranging spuds in a single layer for about two weeks at room temperature in a covered area. After curing, expect potatoes to store for up to a few months or more in a cool, dark place.

While all true potatoes are grown basically the same way, there are variations in plant productivity and disease resistance, and the shape, size, color and cooking quality of the tubers.
There are six basic types of potatoes, each with many varieties. Each has certain characteristics that make them suitable for different cooking methods. The six types are categorized for cooking based on starch content: starchy, waxy and all-purpose or medium. Starchy potatoes are more mealy or floury and preferred for baking, mashing and making fries or chips.
Waxy potatoes have less starch and are more firm, better for soups, potato salads and casseroles or gratins. All-purpose potatoes are in-between.
Russet (starchy) Yellow (all-purpose) Red (waxy) White (waxy) Blue (all-purpose) Fingerling (waxy)
Among these types, there are countless dozens of heirloom varieties available to grow at home. Here’s more info on each type plus favorite varieties to grow. We’re sorry, there seems to be an issue playing this video. Please refresh the page or try again in a moment. If you continue to have issues, please contact us, Russets are the classic “Idaho” potatoes with thick brown skin, often used for baking, frying, and mashing. Russets are low in moisture and tend to dry a bit when cooked, so most cooks add milk or butter when mashing. Good varieties: Russet Burbank, German Butterball Yellow potatoes are all-purpose potatoes perfect for mashing, steaming, boiling, baking, roasting, and frying.
Good varieties: Inca Gold, Mountain Rose, Yukon Gold, Yellow Finn Red potatoes are firm and excellent for potato salads and soups, and for steaming, boiling, roasting, making au gratin, scalloped, and salads. Good varieties: Norland, Klondike Rose, Red Pontiac, Cranberry Red, Mountain Rose White potatoes are low in starch and are excellent for boiling, potato salad, mashing, steaming, making au gratin and roasting.
Good varieties: White Rose, Cal White Blue potatoes, also known as purple potatoes because of their high antioxidant which turns purplish when cooked, have medium starch and are great for steaming, baking and boiling. Good varieties: Russian Blue, All Blue, Purple Cream of the Crop, Peruvian, Purple Majesty “Finger potatoes” are typically the size and shape of a finger.
Early-season potato varieties are planted first in spring and are ready to harvest in 60-80 days. They can only be stored for a few weeks. Mid-season varieties mature in 80-100 days. They typically will store for about a month. Late-season potato varieties are ready to harvest in 100-130 days. They can store for a few months.
Who knew the potato could be so interesting? We did. What are “new” potatoes? New potatoes are any kind of potato harvested while still small. Their skins are still thin and their sugars haven’t fully converted to starch. They are typically sweet, firm, creamy and very waxy.
Use them for boiling, steaming, roasting or in soups, but not for baking. Is a potato a vegetable? The question of whether potatoes are a vegetable often comes up in both gardening and nutritional conversations. The long and short of it: yes. Is a potato a root? Potatoes, because they usually grow in the ground, are often thought of as roots.
But as we noted earlier, they technically are starchy, enlarged modified stems called tubers, which grow on short branches called stolons from the lower parts of potato plants. Do potato plants have flowers? Yes! Potato plants produce small blooms. When the plants start flowering, it’s a good sign to recommit to watering and fertilizing, as the plants are maturing.
In cool climates, potato plants may also produce berries, which are toxic so just leave them be. Image courtesy of Filaree Garlic Farm/Phoebe Webb Photography Not all potato varieties produce flowers during the growing stage, but flowering is usually a positive sign that the underground tubers are healthy and growing into young potatoes.
What part of potato plants are poisonous? Though potato plants also flower and produce small, many-seeded berries like cherry tomatoes, all parts of the plant are poisonous if eaten, except for the tubers. Are green potatoes poisonous? Potatoes that have been exposed to a lot of light or stored too cool or too warm can develop a green color and taste bitter, which usually indicates a high content of “solanine” — a poisonous alkaloid.
Can I plant potatoes in autumn UK?
Can You Plant Potatoes in the Autumn? – You can mimic nature’s natural plan for potatoes by planting potatoes in the autumn. Not all of them – your big planting can wait until spring. But autumn is the time to plant the little potatoes that have turned green in storage, or the ones you found one day while digging in the garden and left outside in a dirty pail.
Gardening experts in Wisconsin recommend autumn potato planting so the plants can establish themselves ahead of cutworms and weeds in spring. I like having a good use for my puniest potatoes. You can expect success planting potatoes in the autumn as long as your soil gets cold and stays cold in winter, with temperatures 8 inches (20cm) below the surface staying below 48°F (9°C).
Buried potato tubers start growing as soil temperatures rise above 50°F (10°C). Your garden gets a vote, too. If you often see volunteer potatoes in your garden, planting potatoes in the autumn should work out well. A bed of cool season veggies invaded by a volunteer potato in Barbara’s garden Please note: If you live in a mild winter climate where the soil does not chill down, it is best to wait until late winter to plant potatoes. The plants can then enjoy uninterrupted growth in mild spring weather and make a crop before the weather gets hot.
What vegetables can I plant in August September UK?
Vegetables –
In the south of England you can still sow quick maturing salad crops such as summer lettuce, radish, rocket, sorrel, chicory and fennel. Continue to sow spring cabbage, turnips, Oriental vegetables and overwintering onions, in the south of England. Sow green manures such as crimson clover and Italian ryegrass to act as a soil improver and to cover bare areas. When dug in, they conserve nutrients and improve soil texture.
What are the best late crop potatoes?
What are the main types of potatoes? – When it comes to the different types of potato to grow, there are three main ones to look out for. These are grouped according to the timings of when they should typically be planted and harvest. The exact timings for when to plant potatoes will vary depending on your location.
Early season potatoes Also known as first earlies, these are the first potatoes you plant in the year and the first to be ready to harvest. They can often be referred to as new potatoes too, and are planted in early spring and then harvested in early summer. They are the first of the annual potato harvests and take between 10-12 weeks after planting. Recommended first early varieties include Rio Grande Russet (available from Burpee) and Rocket. Mid season potatoes These are also known as second earlies. Very similar to early season potatoes, and planted only a few weeks later. They take around 13 weeks to harvest. Both early and mid season potatoes are commonly chitted in order to get an earlier harvest. Chitting potatoes is a simple process to sprout seed potatoes earlier indoors when the outside ground is not yet warm enough for planting. Recommended mid season varieties include Yukon Gold and Red Pontiac, both available from Burpee. Late season potatoes Also known as maincrop potatoes, these have a longer growing season, producing bigger potatoes and a bigger harvest. These varieties are planted at the end of spring and are traditionally ready to harvest late summer and into fall. Recommended late season varieties include Kennebec (available from Burpee), Maris Piper and Russet Burbank. You can also buy late season seed potatoes at Amazon,
Late season potatoes can be lifted in fall and stored through winter (Image credit: Future) Lucy Chamberlain, vegetable expert for Amateur Gardening, adds that late season or maincrop potatoes do store better and last longer than the early varieties.
- Nowing how to store potatoes efficiently means you can enjoy your crop of homegrown potatoes for the maximum amount of time.
- She says: ‘Unlike new potatoes, maincrops are allowed to swell to a good size.
- They stay in the ground until when their skins have set, at which point they are lifted and stored for use during fall, winter and early spring.’ When planning your vegetable growing for the season, take into consideration the timings of when to harvest potatoes variety-by-variety.
Combining growing early and late season varieties can result in the longest potato season possible, from early summer into late fall. Potatoes are an easy crop to grow for a beginner (Image credit: Getty/Mint Images RF)
Can I plant potatoes in October UK?
Updated: June 24, 2021 C an you plant potatoes in fall? Absolutely. But the reason for planting potatoes in autumn will differ greatly depending on where you live. If you live where winters are mild, you probably want to plant potatoes in fall so that you can take advantage of the cooler season and harvest in winter.
If, on the other hand, you want to plant in fall and let your potatoes grow over winter in order to get a jump on the spring growing season, this article is for you. Let’s take a sec to get the legal words out of the way. This article may contain affiliate links.

Can you cut potatoes in half before planting?
Start With Seed Potatoes – Seed potatoes generally come in two different sizes: small, which are tubers that are between one and two inches in diameter, and large, which is anything over two inches. Small tubers can be planted directly—don’t worry about cutting them up. If you purchase large seed potatoes, then you’ll need to cut them down to about the same size as a small seed potato.
Cut them in half, or if the potatoes are really large, cut them into quarters. Make sure that each chunk of potato has at least one eye, which is a small depression in the surface of the potato where the roots sprout. If you need to cut seed potatoes, it is best to wait at least four to seven days before planting them.
Let the cut surfaces “heal” in a cool, dry place to reduce the risk of your seed potatoes rotting.
How long can cut potatoes sit out before planting?
Curing Cut Seeds Before Planting – One way to combat the disease issue is to let your seed potatoes cure for a few days after cutting and before planting. To cure them you simply need to let the cut potatoes sit in an airy, dry place that is out of the sun for 2 or 3 days.
Can you grow potatoes in July UK?
Planting Christmas potatoes in July If you have some spare space in your vegetable garden in July you could put in some ‘Second Cropping’ potatoes for a late Autumn/Winter harvest. Winter seed potatoes are essentially selected early varieties that have been kept at low temperatures to prevent them sprouting; the potatoes are planted in July for digging in late Autumn or left in the ground until Christmas. Harvesting Garlic Now is about the right time to lift garlic which should be harvested when the leaves turn yellow. It is better to harvest too early than late as garlic left too long can shatter and may start sprouting. Loosen the soil underneath the bulbs and gently lift shaking the soil off the roots.
- Be gentle with the plants as as bruising can lead to rot in storage.
- If the weather is dry and sunny (chance would be a fine thing) leave the bulbs outside for 7-10 days otherwise dry in a greenhouse or conservatory with good ventilation.
- Leave the stems and leaves on the garlic which can be plaited for attractive and practical storage.
Keep the best bulbs for re-planting next year if the crop looks healthy. There is some evidence that garlic gradually adapts to local climate so by re-planting every year you can gradually develop your own strain! Tomato Maintenance If you are growing tomatoes in your greenhouse or tunnel and have fruit ripening on the lower trusses like these ‘Sungold’ above it is a good idea to remove the lower leaves to allow more light in to ripen the fruit. Your plants will also benefit from a high potash feed while fruiting which will help improve flavour.
- I find cutting back on watering a little now also improves the taste and will help avoid splitting fruit.
- Green Manures If you have any empty space in the garden that you don’t have earmarked for a follow on crop it is a good idea to sow some green manure now to protect the soil and help lock up nutrients.
Many manures like Phacelia (below) also have very attractive flowers so add a dash of colour to the garden as well as looking after the soil. Charlotte Winter Seed Potatoes Charlotte are our new favourite new potato with impressive yields of delicious pale yelow potatoes. Gemson Winter Seed Potatoes A new second early variety with the delicious Maris Peer in it’s parentage. Potatoes are smooth skinned with a firm, cream flesh.

Source: Mary Now that we have looked into the benefits of companion plants in general, let’s look at which plants are good companion plants for potatoes. First, think about how potatoes grow. They have leaves above the ground, and the roots and potato tubers grow deep underneath the soil.
The roots are mostly above the tubers, allowing for some free space right above the soil level. Good companion plants have shallow roots that won’t interfere with the potatoes. Companion plants should be planted next to potatoes so there won’t be any interference, but it’s always best to avoid any potential issues.
Some good shallow root options include a variety of herbs, including chives, basil, and parsley, Brassicas such as broccoli, cabbage, Napa cabbage, collard greens, cauliflower, kale, and kohlrabi also have shallow roots that will cooperate with potatoes.
- Some sources advise against planting brassicas near potatoes because they make the soil alkaline; however, it shouldn’t be an issue if your soil is neutral or slightly acidic.
- Leafy greens, including spinach and lettuce, also have short roots that won’t compete.
- The potato leaves will benefit the lettuce because they’ll provide shade to prevent the lettuce from burning.
Potatoes planted next to bush and pole beans, fava beans, peas, and lentils will grow bigger, taste better, and produce a bigger yield. Legumes are nitrogen-fixing plants, which means they deposit nitrogen into the soil. Potatoes benefit from nitrogen, so these plants are a good choice.
- Stray away from planting peanuts, however, because those can grow up to three feet deep into the soil, which could stunt the growth of your potatoes as they’ll have to compete for space.
- Potatoes are susceptible to Colorado potato beetles and other harmful insects.
- Planting flowers and certain herbs will help deter harmful insects and attract beneficial ones that will eat pests.
Herbs such as cilantro and thyme are great for drawing in the good bugs. Catnip attracts beneficial insects, too, but it also attracts cats which may see your crop of potatoes as a litter box or bed. Sage and mint deter pests, including flea beetles, but these are invasive and will quickly take over your potato bed.
Try planting these in containers so you can keep them under control. There are so many beneficial flowers for potatoes that it’s hard to list them all! Alyssum, petunia, chamomile, yarrow, borage, lovage, and calendula all attract beneficial insects. Sunflowers attract pollinators like bees, so it’s great to have them near potatoes, too.
Flax and marigold repel potato beetles, so they’re excellent companion crops to plant around the potato bed. Nasturtium functions as a trap crop, which attracts pests that like potato plants. Plant nasturtium close enough to the potatoes that you can attract them but not close enough that they’ll wander away from the flowers.
A few vegetables that are good to grow alongside potatoes include c orn, leeks, onions, garlic, and radishes, Corn can improve the flavor of potatoes, leeks and radishes have shallow roots so they don’t compete, and onions and garlic ward off pests. Companion vegetables are ideal in organic gardening because they allow you to make the most of your space.
Don’t forget that your potato plants may actually help other types of plants, too. A good plant for potatoes to be near is beans as the potatoes repel Mexican bean beetles. In fact, while the potato crop is dealing with the Mexican bean beetles, your beans that grow alongside them will be reducing the Colorado potato beetle population, making both your potato crop and your bean crop better overall by lessening the pressures of insect pests.
What do you plant next to onions?
Best Onion Companion Plants –
Beets : Beets and onions prefer the same soil conditions. The beet is one of many root vegetables on the list of onion companion plants. Spinach : Spinach is often attacked by hungry insects who love to nibble on the green leaves and rabbits who make this leafy plant a diet staple. Interspersing your spinach with some onion plants will help keep these pests at bay and let you enjoy the fruits of your labor just as much, if not more, than your garden invaders. Other plants in the onion genus, such as garlic, leeks, shallots, and chives, make excellent companion plants for onions. They need the same nutrients, so fertilizing them is simpler. Keep in mind when growing onions next to other plants in the onion genus that special attention must be paid to pests because pathogens can pass easily between plants in the same plant family. Brassicas : The mustard and cabbage family plants make great companion plants for onions as they are highly susceptible to insect damage and are a favorite snack for pesky rodents. Planting onions near cabbage, cauliflower, broccoli, mustard greens, kale, collards, and Brussels sprouts is an invaluable way to keep those little annoyances from eating your crop before you get a chance to harvest them. Tomatoes : Onions do very well as companion plants to vegetables in the Solanaceae (nightshade) family. Onion is a pest deterrent to these tasty veggies and will help you get a healthy, bountiful crop when it is time to harvest. Peppers : Another member of the nightshade family, this sweet or hot vegetable can attract insects and rodents to a garden patch. Onions can do a great job repelling insects away from the pepper plants and confusing hungry rodents with the unpleasant onion smell. Planting the two together makes it more likely that those precious peppers will survive the season. Eggplant: This versatile fruit is yet another nightshade crop and a perfect companion to be planted alongside onions not just for utility, which is fantastic because rodents love to eat eggplant, but for taste. Planting eggplant, onion, and tomato together practically invites the ingredients to hop to create amazingly fresh ratatouille during those warm summer nights when fresh garden meals are perfect. Strawberries: Like most items on the list, planting onions near your strawberry patch will keep pests away from your sweet harvest of candy red berries so that you can enjoy them rather than the insects or furry critters that frequent your garden. Potatoes : Potatoes, a root vegetable in the nightshade family, have the same favorite conditions as onions. It seems the biggest benefit is that onions deter pests from infesting potatoes as they grow. Lettuce : Onions and lettuce go perfectly together in a salad and in a garden. Lettuce tends to get eaten by both insects and rodents, and onions do a remarkable job of acting as a deterrent from letting this happen. Plant these two together near some tomatoes when it gets warm and prepare a salad for a delicious meal. Parsnips : Onions do an amazing job keeping pests and rodents away from the late-growing root vegetable, the parsnip. Having the best taste when harvested after the first frost, onions will keep critters at bay long enough to get a good harvest. Carrots : Onions will help keep rodents from digging for your delicious carrots by confusing their scent and taking them off the trail of the sweet-smelling vegetable they are after. Both plants enjoy the same conditions and have a similar growing season making them an almost no-brainer of a companion plant when combined with the pest-repelling benefits. Chamomile : Some herbs and onions make great garden bed-fellows. One, in particular, is chamomile. Up until now, the plants on this list have all been aided by planting onions nearby, but this situation is the other way around. Planting chamomile next to your onions will give the onions a noticeable boost and increase their flavor. Parsley : The herb parsley is akin to the vegetable carrot. The same benefits you get from planting onions with carrots will be achieved by planting onions next to your parsley. Dill : This herb instills great flavor into your onions while the onions boost dill flavor when grown together. Savory : An herb often used in soups and stews, savory is known to help make onions grow larger and more flavorful, lessening the sharpness or bite of the onion and increasing its sweetness. Planting them near each other seems like a no-brainer if you are a big fan of making soup! Marigolds : Marigolds are a great way to brighten up any day, but they are also functional as companion plants. This warm-weather flower does a great job at repelling rodents, but the biggest effect marigolds have on gardens is as a repellant to roundworms called nematodes, specifically the root-knot nematode, which specifically attacks onions and garlic. Roses : Roses are often infested by aphids, which, while usually just a nuisance, can hinder a rose plant’s flower production. Onions are known to serve as a mild aphid repellant, making them a good plant to aid in a pest management regime.

What vegetables can I plant in July UK?
Sow spring cabbage, turnips, Oriental vegetables, chicory, fennel, and autumn/winter salads. Carrots can still be sown, but beware of carrot fly when thinning existing seedlings. Last chance to sow French beans and runner beans (south of England only). Plant out leeks and brassicas for a winter supply, if not yet done.
Can I plant main crop potatoes in June UK?
Early potatoes need around 100 days, and main crops need about 120 days and so planting in May and June will give a great harvest in the late summer.
Can I grow potatoes in June UK?
Protecting from frost – Frost can damage young potato plants, so if freezing temperatures are forecast after shoots have appeared, protect them with a cloche or fleece overnight, or cover with soil. With plants in containers, keep them in a frost-free place such as a greenhouse until there’s no longer any risk of frost outdoors. Harvesting potatoes is the really fun part – carefully lifting your plants to discover the size of your underground treasure is a thrill that never fades, however many years you’ve been growing potatoes. But it can be difficult to judge when to harvest, as the crop isn’t visible. So before you dig up your first plant, gently scoup away some of the soil to check on the size of the tubers. Cover them again if you decide they’re not yet big enough. Early potatoes and maincrop potatoes mature at different times over the summer. Harvest times can also vary across the UK and from year to year, depending on the weather. But as a general guide:
First early varieties should be ready to lift in June and July Second earlies in July and August Maincrop varieties from late August through to October
With earlies, wait until the flowers open or the buds drop. The tubers should be the size of hens’ eggs. With maincrops, start lifting them in late summer for immediate use. You can leave them in the ground until needed, and they will keep growing larger, but the longer they’re in the soil, the more likely they are to get damaged by slugs. Dig up potatoes carefully, inserting your fork at least 30cm (1ft) away from the base of the plant to avoid spearing the tubers. Discard any potatoes that are green, as they’re potentially poisonous. If you only want a few potatoes at a time, try digging down carefully beside a plant with a trowel – you should be able to remove a few individual potatoes without disturbing the plant’s roots, so it can continue growing. Potatoes grown in containers are really easy to harvest, without the risk of accidentally damaging them – gently tip out the contents and pick out your buried treasure. If you want to store maincrop potatoes, delay harvesting until the leaves turn yellow, then cut off and remove all the top growth. Wait for 10 days, then dig up the tubers and leave them in the sun for a few hours to dry, then brush off the soil. Early potatoes are best cooked and eaten as soon as possible after harvesting. Maincrops can either be used fresh or stored for several months and eaten gradually when needed through the winter. Store maincrop potatoes in a dry, cool, frost-free place, such as a garage, in paper or hessian sacks, or on slatted trays in the dark (to prevent sprouting). Only store perfect, undamaged potatoes that are fully dry, and brush off any remaining soil. Check them every few weeks for signs of rotting, and enjoy regularly through the winter months. Aim to finish them before early spring, as they’ll start to sprout and shrivel. Potatoes are easy to grow and usually produce a large, reliable crop. However, they can be affected by several pests and diseases. The main ones to look out for include:
Slugs – can eat the tubers, especially maincrop varieties that are left in the ground during damp autumn weather Potato blight – this fungal disease causes brown patches on the stems that spread and eventually kill the plants. It’s more prevalent in damp weather from mid-summer onwards, so early varieties are rarely affected. Grow resistant varieties in future years and see our guide to beating potato blight Scab – forms rough patches on the skin, but can easily be removed when peeling them and doesn’t affect their flavour. There are several resistant varieties To avoid the build-up of potato pests and diseases in the soil, grow potatoes in a new position each year – see our guide to crop rotation.
Can you grow potatoes all year round in a greenhouse UK?
Out-of-Season Potatoes! In Your Greenhouse Potato Masquerade Growing potatoes in your greenhouse may not seem very exciting or even particularly worthwhile. After all, you can buy a bag of spuds for a few dollars. But imagine growing high-value fingerlings such as Russian Banana, Rose Finn, or Blossom.
These can be hard to find in a grocery store, especially during winter. And they make very tasty salads. Growing potatoes in your greenhouse will provide your favorite varieties all year long, and you don’t need much space to do it. I grow mine in one-gallon or three-gallon plastic bags (available at a local hydroponics store), which I fill with screened garden soil and compost.
Using flexible bags makes it easy for the potatoes to grow freely without the walls of a pot distorting their shape. Your crop can be easily started from seed potatoes. Inspect these carefully and cut away any signs of rot. Larger tubers can be cut in half as long as there is an eye on each piece.
But be sure to allow at least 24 hours for any cut surfaces to harden before planting, or the tubers may rot in damp soil. Some growers also allow the tubers to sprout before planting. As for the planting method, simply put three inches of soil mixed with compost into each bag and bury the tubers about an inch down in it.
Plant one tuber in a one-gallon bag and two or three in a five-gallon one. Then set the bags in a warm part of the greenhouse and water the contents well, but don’t saturate it. As soon as green shoots have reached three or four inches high, add more soil and compost, leaving an inch or so of sprout showing.
For cleaner potatoes, you can add aged, damp straw or shredded leaves instead. Continue this process as the sprouts grow, until the surface of the planting medium is about an inch below the bag’s top. Also, be sure to feed your plants with a high-phosphorus fertilizer, such as 5-20-0, which root crops prefer.
After the plants come into flower, you can early-harvest some “new” potatoes by carefully removing a few from around the edges of a plant. Eventually, the plant tops will die back, and the entire crop can be harvested. To do this, simply upend the contents of each bag into a container and pick out the potatoes.
