Wait until all the foliage of the plant has withered and died back before harvesting mature potatoes. After the foliage has died, dig up a potato from one or two plants and rub the skin of the potato with your fingers. The skin of a potato that is ready for harvest won’t scrub off easily.
How do you know when it’s time to dig up potatoes?
It’s time to dig up your tender, homegrown potatoes when the buds drop or the flowers that do bloom begin to fade. Another good indication is seeing unopened flower buds dropping from the plant. At this point, the leaves will still be green but some will begin fading to yellow.
What do potato plants look like when ready to harvest?
Soon after your potato plants reach maturity, they come into flower. The plants continue to grow for the next several months, and eventually the leaves and stems start to turn yellow and flop over. Mature storage potatoes are ready for harvesting a few weeks after the foliage has turned brown and died back completely.
Can you dig potatoes before they have flowered?
They are generally planted around late April and should be ready for harvesting about 10-12 weeks later. Again, and as for earlies, they will not be ready for harvesting until they have at least finished flowering. A test dig will reveal whether they are a good size and ready for lifting.
How long can potatoes stay in the ground?
Once the plant dies, the potatoes are finished growing in size. However, the skin on the potato does harden and cure to make it stronger for storage. We recommend leaving the potatoes in the ground for about 2 weeks after the plants have died off.
What month are potatoes ready to harvest?
Generally, “new” potatoes are ready approximately 60 to 90 days from planting, depending upon the weather and the potato variety. One sign that young potatoes are ready is the formation of flowers on the plants. At this stage, the potatoes are usually less than 2 inches in diameter.
Can you leave potatoes in the ground over winter?
Yes, you can actually grow potatoes from last year’s crop. If you left some tubers in the ground over the winter after last year’s harvest, however, don’t use these as seed potatoes. If they do sprout, pull them up, as they will probably result in weak plants that produce small and inferior crops.
What do potato blooms look like?
Potato flowers look very much like tomato flowers except instead of being yellow, the potato flowers can be white or lavender or pink. It depends on the type of potato as to the flower color. Most years, July and the beginning of August are hot and sometimes dry months.

When to dig up potatoes after flowering?
(See each variety for days to maturity.) The tops of the plants need to have completely died before you begin harvesting. “New potatoes,” which are potatoes that are purposefully harvested early for their smaller size and tender skin, will be ready for harvest 2 to 3 weeks after the plants stop flowering.
Can you harvest potatoes too early?
The plant could look large and healthy, but the potatoes themselves may only be small and immature. If you harvest your potatoes too early, you can miss out on a heavy crop, but if you wait too long, they could be damaged by frost. To pick the best time for digging potatoes, watch what’s happening with the foliage.
Do potatoes continue to grow after flowering?
As soon as potato plants come into flower, you know they’ve reached maturity and have begun to form their below-ground tubers. The plants will continue to grow and flower for several months, and eventually, they’ll naturally begin to die back.
Can I leave my potatoes in the ground too long?
Generally speaking, storing potatoes in the ground is not the most recommended method, especially for any long term storage. Leaving the tubers in the ground under a heavy layer of dirt that may eventually become wet will most certainly create conditions that will either rot the potato or encourage sprouting.
Can you leave potatoes in the ground after the plant dies?
For the best storage potential, mature tubers should not be harvested for at least two weeks after the foliage above ground has died. This waiting period allows the skins of the tubers to thicken, which is key to long term storage. The ideal range for harvesting storage potatoes is 13-18°C (55-65°F).
Can you eat potatoes that have been in the ground for a year?
A: If the potatoes are still firm and the skin is not green, yes, then you may certainly eat them. When you harvest them, inspect them for diseased looking tubers. Practice crop rotation and plant the potatoes in a different area than they were last year.
How long is potato season?
Growing Season Length The growing season for potatoes can range from 75 to 135 days.
What happens if you don’t dig up potatoes?
If you don’t harvest potatoes when the plant dies back, a couple things could happen. Most likely they will rot if the soil is wet, or they’ll die once the ground freezes. But if you live in a warm and dry enough climate, any tubers that survive over the winter will sprout again in the spring.
What happens to potatoes in winter?
Potatoes that you plant in autumn will start growing their roots during the winter. Plus, they will start growing above ground as soon as the soil warms up. This lets your plants get well established before pest arrive.
