Leave time between tillage and planting to allow green matter to break down; weeks is a good time frame. Consider waking up your potatoes in mid-February by green-sprouting them for several weeks before planting.
Be careful when handling them to avoid breaking off sprouted eyes. Seed over 2 oz. You can cut the potato any which-way to achieve this. Avoid cutting eyes if you can when making your cuts. Some folks like to let seed pieces dry before planting. You may wish to lay drip tape into the trench next to your seed potatoes to conserve water and to ensure that any water you put out gets to your crop and not your weeds.
Cover seed and drip tape, if used with several inches of soil and tamp lightly…. In the southeast, potatoes are grown from March to May-July, depending on varietal days to maturity.
Hilling uproots weeds as you pull the soil up around the potato plants. If potatoes are exposed to sunlight, they will start to photosynthesize and produce a green pigment under the skin.
With that in mind, if you see any potatoes at the soil line, be sure to cover them promptly to prevent greening. Depending on the weather and your soil type, we can provide the potato plants with better drainage by periodically pulling up soil around the growing stems. Heavy rains will run off into the aisles and away from the potatoes. Potatoes form two types of stems; one for above-ground growth, on which we see leaves; one for below-ground growth, on which we find tubers.
By covering growing leaf shoots with soil, we are creating more below-ground stem. Once a portion of the stem is buried with soil, it will produce the tuber-forming stems that will then form potatoes. Cool, huh? A bit sneaky on our part, but fascinating to observe. This is also why you may notice different sized potatoes on your plants at harvest; the longer the underground stem was under the ground translates to larger potato size and your preceding hilling activites.
Just loosen surrounding soil in the bed and pull up around the leaves and stems. Try to hill before the stems grow too long and start to flop over. Potatoes need different amounts of water at different times in order to produce to the best of their ability.
Generally, potatoes need between inches of water per week; this could be provided by rain events or you to make up the difference. Count the days from planting to figure out target harvest dates per potato variety. You can always dig around a bit to see how things are coming along. Generally, new potatoes will be present by day 60; they will be small and fragile.
Most varieties will have good-sized tubers that are ready to harvest by 90 days. In the Southeast, soils get too hot in the summer to grow great potatoes. Varieties with DTM beyond days is not advisable. Shoot to have all your taters up by the end of July at the latest for best quality. If you are growing on a small-scale, nothing is more rewarding than digging up your potato crop by hand. A digging fork or a broad fork work very well. Freshly cut seed potatoes can become dehydrated, fail to heal properly or develop disease, preventing growth.
Freshly cut potatoes need oxygen, high humidity and soil temperatures between 50 and 65 F to heal properly, if the soil does not offer these conditions, cure the seed potatoes before planting. If the soil does meet these conditions, plant seed potatoes immediately after cutting.
Curing protects potatoes by allowing them to form a protective covering on exposed cut surfaces. To cure cut seed potatoes, allow them to sit in a room with a temperature of about 40 F for six to 10 days. Make sure the seed potatoes receive good air circulation and relative humidity of 85 to 95 percent to promote healing and prevent dehydration.
After curing, move the seed potatoes to a warmer room at about 70 F and allow them to sprout before planting. Based in Indiana, Molly Allman holds a B.

Sincerely, Katrina.
Please remember that tires are full of chemicals that will leach into your potatoes. Please reconsider this idea! Your health depends on it! Hi Katrina: You can grow poatotoes in tires or garbage cans. Basically this is a way to contain the potato plant—to grow potatoes in limited space.
This method of growing is very similar to growing potatoes in hills. To plant in a hill, you mound soil to about 3 feet across and a half foot high and then plant your seed potatoes in the hill about 6 inches apart from the center of the hill. Bury the seed potatoes under 4 to 5 inches of soil; soon the leafy vine will appear. When the vine gains some height, hill up to the top most leaves keeping the developing tubers covered; continue hilling and growing more and more tubers. Using tires, turn the soil where you intend to plant to about 6 inches deep; add compost to the soil.
Set the tire on that spot and fill it with soil and compost. Add 3 seed potatoes and cover them with soil as above. How do I tell if my potatoes are an early, mid or late variety? Early-season, mid-season, and late-season when it comes to potatoes refers to the number of days from planting to harvest at maturity.
Early potatoes take 90 to days; mid-season take to days, and late-season take to days. To know for certain if a potato is early, mid, or late, you would need to know the variety. There are many, many varieties of potatoes—some are easily identified by their size and look. You could take one of each type growing in your yard to a nearby farmers market and get a potato growers identification, or to the county extension office.
You may have several varieties growing in your yard. If you live in a warm region where potatoes do not die back and live on as perennials, you could next season, count the days from flowering to harvest and know relatively certain if you are growing earlies, mids or lates. You will know your potatoes are mature and ready for harvest when the vines yellow and die. Aim to complete your harvest before the rainy and cold season.
Early, mid or late matters not. Usually for storage potatoes are dug when the top foliage die off. But one can dig any time after the flowers have appeared.
Leaving longer in the ground only allows the tubers to get larger. If you have plenty dig when you feel the spuds are large enough for your purpose. Here are a series of pictures on growing potatoes in a box. Clearly there is no advantage in carrying out excessive hilling when growing potatoes. The purpose of hlling is to insure the tubers are covered. For comparison one Pontiac Red was dug in the same row, which was almost identical to the test box potato in appearance.
I have read over and over NOT to use super market potatoes as seed. This past fall, I bought bags of taters very cheaply at an outlet store. What we had not used up by early spring began to sprout in the box where they were stored in our cellar. They quickly grew into plants! I just harvested about 50 lbs from my garden of varying sizes of beautiful red spuds.
Truly you have a bountiful harvest! The advice not to plant potatoes you buy from the grocery store comes from the practice of some growers and grocery chains to chemically spray potatoes to prevent the eyes from sprouting.
This allows the potatoes to stay longer in storage or in the produce bin. But if the produce person is buying fresh and turning his potato inventory quickly, there is no need to chemically treat potatoes.
Seed potatoes can be planted whole or cut into pieces with 2 to 3 eyes. They are very tender and cannot tolerate frost. Potatoes can tolerate cool soil but can rot in excessively cold or wet conditions. About 50 to 60 days after planting you can begin to reach down into the soil to check for new potatoes. Thanks for an informative page.
As mine are in containers, would it be advantageous to move them into a spot with only morning sun once the temps get up to the eighties? Also, I was considering layering with pet bedding supposedly non-cedar and sterile or straw-what do you think? Thank you for your time. Try moving the plants into morning only sun and straw mulch—especially if you expect extended temperatures in the 80s. You might also look for heat-tolerant varieties for next year. Do you agree? Any advice? Removing flowers from the potato or other vegetables will direct energy to tuber or fruit development.
However, when you remove a flower you are also reducing your potential crop—so pinching away blossoms should be reserved for mid- to end- of season when you want the plant to concentrate on developing the already existing tubers. Potatoes require lots of water for full tuber development—so you must keep the soil evenly moist when tubers are developing, or you will get small tubers.
Small potatoes are often found in gourmet groceries—so take heart, you are gourmet gardener. Potatoes should be ready to harvest about 10 weeks after planting. Potatoes can be harvested as soon as they begin forming new potatoes or as they mature. Determine the size of the tubers by digging into the side of the hills.
Where temperatures are warmer than the mid 30sF, potatoes will not store long. They will send out shoots and want to start growing. Find the coolest location you can to store the potatoes.
You will likely need to eat these sooner rather than later.
