After the greenery has died back, potatoes can stay in the ground for several days, if the conditions are right. As long as the soil is dry, and the temperature is above freezing, you don’t have to harvest potatoes immediately. But it is best to dig them up within a few days to prevent rotting.
When should you pull potatoes out of the ground?
The flowers and foliage determine when to best harvest your crop. Harvest baby potatoes (new potatoes) two to three weeks after they’ve finished flowering, and harvest potatoes for storing (mature potatoes) two to three weeks after the plant’s foliage has died back.
Can you dig up potatoes too early?
Dig potatoes too early, and you’ll harvest a measly crop of minuscule tubers. You’ll also risk stressing the plant and its precious root system, so although you could try replanting it, the plant might not thrive. Wait too long, and your potatoes may get damaged by frost, or begin to sprout, crack or rot underground.
Can you leave 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.
