Can You Leave Potatoes In The Ground Over Winter

You can leave potatoes in the ground over winter in some cases. If you live in an area with mild winters, you can cover the potato plants with a layer of mulch to protect them. In more extreme cases, you may need to dig up the potatoes and store them in a cool, dark place.

If you are planning on storing your potato harvest all winter, you will want to curing the potatoes that you are saving for around two weeks. Other varieties might not survive all winter, but most potatoes will survive for at least one or two months if stored properly. Mature potatoes are less prone to bruising during harvest compared with unripe potatoes, and they last longer when stored.

Newly harvested potatoes have very thin skins and are susceptible to breaking, leaving tubers exposed and susceptible to rot. If you fail to harvest the potatoes at all, they can germinate and grow new plants in the following spring (after the winters dormancy). If, however, you do leave a few tubers in the soil during the winter following a harvest from the previous year, do not use them as seed potatoes. The seeds could potentially be used to start new potato plants, though that is usually not done, since potatoes from those plants will not grow faithfully to the original tubers.

Well, once tubers are grown, potato plants will begin yellowing, and then they will get increasingly brown and wizened, until they completely wither. A potato plant that has clearly died, with leaves clearly brown, gray, or outright dead, is not going to keep producing tubers – at least, not ones that you want to eat. Potato plants or budding pieces that are sprouting will stay dormant if planted in too cold, too moist, or too dry soil.

Learn why you should not leave potatoes in the ground

If a fall freeze kills the above-ground potato plants, underground tubers may lie dormant until spring, when they begin sprouting to produce new plants as soil warms. If a spring frost kills the potato plant above ground, the underground parts can still send new sprouts and keep growing.

Although potatoes are a cold-weather crop, hard frosts or freezing temperatures kill plant growth above ground. Potatoes are vulnerable to damage during the cold weather due to wind chill, low humidity, and moist soil conditions. Potato lethal leaves and flowers, and tubers themselves, can turn green and poisonous if exposed to sunlight, so keeping the lethal leaves and flowers of potatoes shaded is crucial while keeping them stored in the ground. Potatoes are susceptible to several other diseases, most of which really only impact the growing tuber, which either stunts underground or becomes a disease in its own right.

Leaving the tubers in the soil beneath a heavy layer of soil, which can ultimately get moist, is sure to produce conditions that either will cause the potatoes to rot or promote sprouting. By burying tubers beneath a thick layer of soil that can get moist, you are creating an ideal environment for a potato to rot or to sprout. Allowing my potatoes to sit in the soil for an additional couple weeks allows the tubers to develop thick, tough skins, essential to storing safely so they are protected from rot or disease.

Now you know how to dig up potatoes and properly curing, you will be able to enjoy potatoes from your very own backyard long into winter. If you choose the right place, the cool potatoes from your yard last several months, allowing you to enjoy them throughout the winter. You can plant a budding potato in spring, assuming it looks healthy and was free of diseases in the prior season.

Any leftover potatoes that you find sprouting in the box at the beginning of the spring are great to plant in the garden. Potatoes are typically planted early spring, but if you live in a cold area, you may want to plant in the late fall, or even in winter. Do all of what you would normally do when planting potatoes, except plant right before the first freeze you get during fall/winter. If you live somewhere that has a mild winter, then you will likely want to plant potatoes in fall to get the benefit of a cooler season, with a winter crop.

In colder climates, you might dig up potatoes in the spring and store them in a cool place before planting season. As long as the soil is dry and temperatures are above freezing, you should not have to harvest the potatoes right away. Plan on digging your stored crop of potatoes just before the soil freezes over (if this happens in your area), but the best time is to do so on a warm, dry day after several days without any rain (if there is any rain, wait for the soil to dry out a few days longer before starting the crop). When potatoes are done growing, I like to keep my potatoes in the ground and harvest when needed, instead of digging out an entire crop immediately.

My potatoes hold up really well in-ground, but I really do harvest within a couple weeks of maturity, and definitely well before winter sets in, as I can expect ground in my area to freeze. In this image, the last little bit of my potatoes has been harvested, and my garden is now ready for tillage ahead of winter. Once I harvest all my summer garden crops, my family will be plowing through our potato patches and making our winter crops. Your crops are ready to be harvested when the plants are dead, and when the potatoes skins are toughened up, no longer prone to easily flaking.

Once your potato plants are flowering, you can pick tender (and extra delicious) new potatoes whenever you have got the craving during the growing season (which is exactly what I did with the potatoes in the bins in the first picture), but at some point, you will want to pull your remaining potato harvest from the ground before it ices over (which happens fairly early here in Wyoming). Plus, even potatoes that grow longer do not reach maturity until the winter, since they have had all spring, summer, and fall to grow. Fall planting may be the way to go, too, if you are having trouble getting potatoes out of the ground before pests blight the plants. Your potatoes will have roots growing in the offseason, then when the weather turns, your potatoes will burst out with above-ground growth.

The upshot is, very early spring (unless you live in the colder parts of the country) You will have big, robust, beautiful potatoes well before your neighbors get a chance to pick them. After the greenery has died down, potatoes may remain in the ground for days, if conditions are right. You can still keep your supplies fresh, keeping potatoes for at least several months, using this method.

What happens if I don’t harvest my potatoes?

Several things could happen if you don’t harvest potatoes as the plant dies back. They will probably decay if the soil is moist, and if the ground freezes, they will perish. However, any spring tubers that survive the winter will emerge anew if you reside in a warm and dry climate.

How long will potatoes stay good in the ground?

It is not advised to leave potatoes in the ground. The tubers, however, can remain undamaged in the soil for up to 14 days after the leaf has died. The potatoes may even survive until the late fall or early winter in colder locations without sprouting.

How do you store potatoes in the ground?

Place a trash can horizontally in the ground and bury it so that the bottom is at least 31 cm deep. Use clean straws or waste paper to fill the can with potatoes. If necessary, cover the cover with just an old blanket to block the sun and fasten it with a bungee cord.
