Potatoes can chit in a cool greenhouse environment, providing numerous benefits. Chitting is an easy process that encourages the potatoes to start sprouting before planting them in the greenhouse. It can be started from late January or February, with a view to planting about six potatoes. Potatoes can be planted undercover, allowing for chitting to be started even earlier. Growing potatoes in containers can be started as early as mid-winter in a heated greenhouse to provide a better growing environment.
Chitting seed potatoes should be placed in a light, dry room, porch, on a windowsill, or in a greenhouse if you have one. The ideal temperature for chitting seed potatoes is cool but not near freezing, as they can get damaged. Avoid high temperatures, such as those in a heated room, as this can cause the seed potatoes to shrivel.
Seed potatoes can be found in garden centers or mail order companies from January. Place the seed potatoes in a light, dry room, porch, on a windowsill, or in a greenhouse if you have one. The ideal temperature for chitting seed potatoes is cool but not near freezing, as they can get damaged. If direct sun isn’t available, a porch or greenhouse could be suitable. In the south, a polytunnel may be frost-free.
Chitting potatoes is beneficial, as it allows short shoots to grow and give them a good start when planted out later. Egg boxes or empty seed modules can be used for chitting, but indoors is recommended due to potential damage from frost and excessive light.

It’s time to start chitting your potatoes. It’s very easy to do, but very important. Here’s how I chit mine.
Can potatoes be too chitted?
Chitting potatoes involves restricting the number of shoots to increase the number of large potatoes that form. The theory is that leaving all chits on a potato results in a mixed-sized harvest, while restricting to two chits yields fewer tubers but larger ones. Too many shoots may result in lots of little potatoes, but this is ideal for planting first earlies. If a chit is knocked off, it will grow a new set. To properly chit potatoes, place them with the eyes facing up.
Do potatoes do well in a greenhouse?
Squash and potatoes can be grown year-round in a home greenhouse, with the latter being ideal for winter or early spring. Squash can be started in March or April, with consecutive plantings through May to prevent ripening all at once. Squash is easy to grow but requires a lot of garden or greenhouse space. To start seedlings, plant squash seeds about an inch deep in a seedling-starting mix, which can be purchased from local retailers or mixed with potting soil, medium sand, perlite, and compost.
Peat pots are ideal for starting seedlings, as they decompose into the soil. Most squash varieties require soil at least 65 degrees Fahrenheit for germination, so a heat mat may be necessary. To prevent failure, keep the soil moist and avoid allowing seeds to dry out.
What is the best way to chit potatoes?
To sprout seed potatoes, arrange them in egg boxes or seed trays in a cool, frost-free room with eyes up. Label each variety and start indoors in February. Early varieties should be planted in February, followed by planting in April. Maincrop varieties should be planted in early April after sprouting indoors. Seed potatoes, egg boxes, and plant labels are needed. The sprouts should be ready for planting when they reach 2cm in length, which takes 4-6 weeks. Planting maincrop varieties in early April after sprouting indoors is recommended.
Can you store potatoes in a greenhouse?
After lifting potatoes, they need to be sorted and dried before they can be stored. If it’s sunny, lay a tarp on the ground, otherwise, place them in a shed, greenhouse, or garage. Sort through the potatoes, brushing off excess dirt. Do not wash them as they won’t store well. Look for damaged potatoes, such as holes or holes, and discard them. Soft and squishy potatoes should be thrown away. Small potatoes can be disposed of, but compost them. All healthy potatoes should be laid out on a tarp for a couple of days to dry. If necessary, they may need to be dried inside. Once dried, they can be stored.
Can I chit potatoes in a greenhouse?
It is recommended that chit seed potatoes be placed in a cool, dry environment, such as a room, porch, windowsill, or greenhouse. The optimal temperature range is 7-12 degrees Celsius, with the plant receiving indirect light throughout the day. It is advisable to avoid high temperatures, as they have the potential to cause the plant to shrivel. The optimal appearance of sprouts is characterized by a short, stunted growth pattern, a deep green coloration, and a hue that approaches purple. Should the shoots require removal, it is recommended that only the larger ones be discarded.
What temperature is too hot for potatoes?
Potato plants are susceptible to hard frost and withering when temperatures are consistently over 100 degrees. They also fail to set many tubers when nighttime temperatures remain over 55 degrees. Most potato varieties require 80 to 110-degree days for full size development, which is not often available in the spring. To grow “new potatoes”, choose seed potatoes from a local nursery or garden catalog with shorter harvest days, such as red, white, yellow, or blue potatoes.
What happens if you don’t chit potatoes?
Potatoes are a staple vegetable crop that can be grown from seed potatoes, which are small tubers typically planted in spring. Early varieties can be chitted to encourage sprouting before planting, allowing for an earlier crop. As the plants grow, soil can be gradually piled up around the stems, known as earthing up, to bury the developing tubers. If space is limited, you can grow a few potatoes in a small bed or large container. You can also grow a winter harvest by planting in a large tub in late summer and protecting the plants from frost in a greenhouse or sunny porch.
This guide will help you with each step in successfully growing potatoes. Enjoy the thrill of digging up your first new potatoes of the season, steamed and served with butter or mint, as a highlight of early summer.
How to store potatoes in a hot climate?
Potatoes and sweet potatoes thrive in dry conditions, particularly in a cool, dry basement with temperatures ranging from 50 to 60° F (10 to 15° C). They need protection from light and can be stored in various ways, such as bins and boxes under the bed, half-bushel baskets, small bins with loose-fitting lids, cardboard boxes, an old dresser with partially opened drawers, or plastic or wooden crates.
- Place cured potatoes in a burlap bag, tucking them into a plastic storage bin left open a wee bit.
- Line plastic laundry baskets with newspapers, with potatoes arranged in layers between more newspapers. Place the packed, covered baskets in an unheated garage.
- Make short towers of potatoes by stacking them between layers of open egg cartons. Cover the towers with cloth to protect the potatoes from light.
- Place sorted potatoes in small cloth shopping bags lined with plastic bags and store in a cold space under the stairs.
- Use an old dresser in a cool room or basement for winter storage, leaving the drawers partially open for ventilation.
- Place potatoes in a shady spot outdoors, covered with straw, a second tarp, and a 10-inch blanket of leaves or straw.
- Bury a garbage can horizontally, place potatoes in the can with shredded paper or clean straw, secure the lid with a bungee cord, and cover with an old blanket if needed to shade out the sun.
Can potato plants get too much sun?
Potato plants require adequate sunlight for optimal growth and tuber development. However, excessive sunlight can cause issues like leaf scorch, while insufficient light can lead to spindly plants and poor tuber development. The intensity and duration of sunlight exposure are crucial for a potato plant’s success. Full sun, at least 6 hours of direct sunlight, is ideal for robust growth and optimal tuber production. Light quality also plays a significant role in potato health, with blue and red wavelengths being particularly important for healthy growth.
Can potatoes be chitted in a greenhouse?
It is recommended that chit seed potatoes be placed in a cool, dry environment, such as a room, porch, windowsill, or greenhouse. The optimal temperature range is 7-12 degrees Celsius, with the plant receiving indirect light throughout the day. It is advisable to avoid high temperatures, as they have the potential to cause the plant to shrivel. The optimal sprout should be relatively short, stunted, and green with a purple hue. Should the shoots require removal, it is recommended that only the larger ones be discarded.
What is the fastest way to get potatoes to sprout?
Chit potatoes by placing them upright in an egg box in a light, airy, frost-free place, such as an unheated room. If heated, the process will speed up, but avoid leaving potatoes in warm and dark conditions. Choose your potatoes based on their production time, with first earlies ready from June to July, second earlies from July to August, early maincrops in August, and late maincrops from September onwards. Plant chitted potatoes in early to mid-spring, as soon as the soil has warmed up to about 6°C.
The longer the potatoes can grow, the higher the yields. Potatoes prefer rich, deep soils in open sites, but are not fussy about soil types. If you can dig in manure or compost the autumn before planting, the better. Excessively heavy or wet soils can affect the potatoes’ skin, encourage rust spots, blight, and attract slugs.
📹 Sprouting Potatoes – Everything You’ll Want to Know!
Sprouting potatoes sounds a simple task, but only if you have done it before. Over the years I have had so many questions based …
Just on the point on rubbing off long, white shoots from potatoes that have sprouted in the dark, I did a small-scale experiment last year. Basically, all my homesaved seed potatoes that I had overwintered in the garage had sprouted by the time that I unwrapped them from the newspaper that I had put them in and had long, white spindly shoot. On half of them I snapped off the shoots. On the other half, I just left them on. I put both halves onto windowsills to ‘chit” between late Jan and early Mar. The tubers that I had snapped the shoots off all generated new chits that were short and stumpy. The tubers that I had left the spindly white shoots on didn’t grow new chits but all the spindly white shoots darkened up nicely. When it came to harvesting, I got approximately 10% higher yield from the tubers that I had NOT snapped the spindly white shoots off. Only a small experiment (3 tubs of each) but interesting result.
Last year was my first year planting potatoes. They were ones from my cupbord and they all had long spindley sprouts. Planted them all and got nice big potatoes from them. Granted there weren’t a lot of them, but I also inadvertently planted them in an area of my yard that had a concrete slab buried about 1 foot under the soil. I only top planted with straw over the tops so I was happy with the amount I ended up getting (roughly 30 to 40), so you can actually plant the long spindley sprouts.
I grew up in Jersey, website Islands and my relatives were potato farmers. They always had sheds full of potatoes stood together in boxes, which were put there to sprout. So I was surprised when you said farmers don’t do it. But Jersey farms are much smaller than UK farms, and the soil they plant in is always warmer because it’s on a hillside facing south.
Here in Sweden we have to wait a little longer. I get my seed potatoes delivered tomorrow and will plant them out late april or first week of may, weather permitting. Hope to have some new potatoes around June 26 as it’s tradition to eat new potatoes & pickled herring on Midsommer Eve. I will be growing Rocket. Orla. Nicola. Jazzy & Sarpo Mira. Hope you will have a great spring and summer! Thank you for sharing all your knowledge!
I selected my seed potatoes from the Piggly wiggly and my favorite Aldi’s. Make sure u get the organic potatoes because the others are sprayed to not sprout even though some do im planting the first week in March in Wisconsin this year they already planted potatoes in Canada 😅 happy gardening 😅⚒️⚒️⚒️⚒️⚒️👍👍👍
Thanks for the great information. As usual- lots of valuable tips! I have been growing sprouted supermarket potatoes in greenhouse pots for about a decade. Generally- each gardening year, it is an alchemist situation where old sprouted (free) potatoes transform into tender small new potatoes. I do it in a completely lazy way- so my resulting crops are the same amount as planted but transform into my preferred tender small potatoes. My growing space is limited- so the pots go wherever they can fit in the “walking aisles” (layered cardboard and wood mulch) of my small raised bed gardens.
That’s interesting about removing the other eyes from a potato and leaving just the sprouts at the top. I’ll try that with some of my potatoes this year, for sure! I’ll use your advice to pick out the egg-sized tubers at my garden center, too, rather than going for the big ones or small ones. You pack in a lot of potato knowledge in your articles! Have a great growing season! 😀
Having been brought up on a farm growing commercially back in the 50s then my grandfather always chitted his seed potatoes and they would be planted by local women by hand. I still do that today with my earlies which I only grow because a few early spuds grown by myself always seem to taste much better lifyed that morning. I grow mine in plastic drums good mix of farmyard muck and compost. Good info from this gent.
I’m in North Carolina in the US and I’ve been perusal you for my second year now. I checked out several podcasts and have settled on your’s for my container potatoes. Last year was my first year attempting all container crops and did okay because I was still very new. I saved 3 dozen of the 4 varieties of potatoes and this year payed close attention to your suggestions for starting. Chose my egg sized potatoes and put them in egg cartens in the window until the chits were about 1 to 2 cm tall. I put them in 10 gallon (40ish liter ) bags on April 7th. I placed them on a pallet and used the tractor to move them in barn at night and into the sun during the day. At this point, they’ve grown enough through the straw to add more soil and straw and all I’m doing now is watering and giving them bone meal every 2 to 3 weeks. Will only add straw from here on and expect to be able to harvest mid to late July. Did a second sprouting and planting today 5/11 og the indeterminate type and removed all but one or two chits as you suggested (the April planting were all 1st and second earlies). Just wanted to thank you for all your wisdom and I’ll let you know how it turned out.
Do you know, if you had said to me start doing some gardening 4 years ago I would have said, It happens too slow and I have not got time. How ignorant was I? And I am the first to admit it now. I retired and started doing a bit. Now? I’m absolutely loving it. Wish I had started years and years ago. I have even invested in a 10 x 12 greenhouse…..lol perusal your articles makes me more keen to try stuff I would not have dreamed of. Brilliant website…… Totally inspiring to me. All are well set out and your explanation of things is just right. A lot of articles on youtube you stop after the first 30 seconds or fall asleep before that. Thank you for all the info you give. I dont usually post comments, but I feel here credit where credit is due. Well done!
Hi Tony, Fantastic article. I live in France and got my charlotte spuds from my local nursery. Everything you mentioned in your article I experienced. It was like de ja vue. As you said, growers are less inclined to supply seed potatoes the size of eggs. I had a bag of 110 and I reckon they were half the size of a standard egg. I put mine in one of my cellars 14°C and covered them up and removed the light (first year of growing my own) and the outcome exactly as you described. They are now de-chitted, standing the right way up in eggboxes in my greenhouse – thanks a million. Power to your elbow my friend!!!!
I learned a lot from this article! I didn’t know the ideal potato size to sprout is large egg sized or the ideal temp. Very helpful! I ordered my seed potatoes and they will be delivered about 6 weeks before my last frost date so I will ensure I start the sprouting process in a south facing frost free environment asap. Thanks for the tips!
Great article Tony. I’m chitting some purchased first earlies, as usual, this time of the year. Growing up, we only ever planted maincrop potatoes purchased from the supermarket, though. A lot of Americans do the same, and the typical planting style there is to cut the spuds in half and then throw them into the ground to grow. They’re pretty resilient tubers, and I don’t think rot very often from a cut if planted once the soil is warm.
I have grown them from healthy sprouts like you do slips, but it isn’t easy. You can plant them with long sprouts if you let them turn green or color up in the light. There is also the issue of hardening them off. The sprouts are not used to the dry sun. I have also planted them in the previous fall. They seemed to come up about the same time when I planted the ones I sprouted. The only advantage to that is not having to store them, or sprout them. You do have to plant them deeper, mulch them.
I have begun my journey on potato farming in raised beds with lots of lovely stumpy sprouts and heaps of compost mixed in to my soil. I’ve learned so much from you, very excited to see my little buddies grow in beautiful grean plants. Thanks a million for the expertise you give out. 2 Q’s please: harvest when flowering plus a week/2wks? Should I always add hard wood ash to soil or only if PH is below 6? Cheers!
I have to share with you that my interest in growing potatoes resulted from a pot that was left under my house that had a potato in it that I don’t remember planting I suppose… But in early spring, I saw some green growth coming out of the pot so I said the pot aside Low and behold a month later I had this beautiful growing plant, but I was waiting to see what it was… And what’s down in the soil but four small tiny red potatoes and a large yellow potato… Just under the surface! And that defies all processes in growing potatoes because somehow it survived under my house, all winter in the Chicagoland area!so now I’m going to officially grow potatoes following your guides. Thank you.
You never sprout potatoes. Don’t harvest everything that you grow. Leaves some potatoes at the same spot. They will root in the fall and come back next year at the right time. Even if some may be killed by frost, they will still be able to come back later. This way your potatoes will have a head start and grow really quickly once the temperature rises. No sprouting is needed. LOL
Thanks for the tip of reducing the amount of sprouts, makes perfect sense! I’ll have to disagree on dark sprouted potatoes though. I really don’t have a choice, because I can’t set them safely until the 20th of May (coastal arctic Norway), but my cellar begins warming up and sprouting them in the last week of April. But the results are excellent, better than anyone in my village. My reasoning is that it’s no different from setting unsprouted potatoes, they will blanch in the dark soil. On the contrary, I suspect bright sprouts waste energy chlorofylling their sprouts and then changing their mind about it. Farmers in my region set potatoes semi-automatically, with labourers riding on the machine and hand feeding the setting cups. So that is gentle enough for sturdy light-sprouted potatoes, but not for spindly dark-sprouts. And so I think that is why all the hobbyists also light-sprout here.
What a wonderfully thorough article, Tony!! You’ve left nothing out! Thank you for clearing up the indeterminate/determinate question! We don’t call potatoes early, first early, main crop here.. just go by indeterminate/determinate. Now it all makes more sense! Had a great giggle at the “thumbs down n’ frown” on the white shoot!😆 Have a great weekend, my friend!!💚
