After harvesting, potatoes must be cured. Let them sit in temperatures of 45 to 60 degrees Fahrenheit for about two weeks. This will give the skins time to harden and minor injuries to seal. After the potatoes have been dug, brush the soil off. Do not wash potatoes until you’re ready to use them.
How do you harvest baby potatoes?
You can harvest “new” potatoes once the canopy flowers have bloomed, which is usually about six to eight weeks after the potato plants begin to grow. These baby potatoes range from one- to two-inches in diameter. Excavate lightly next to the plants and gently dig out a few tubers from each plant.
What happens if you harvest potatoes too late?

How long after potatoes flower are they ready to harvest?
Most early potato varieties will produce flowers in June, quite pretty ones too. Many are white, but they come in purple and pink too.

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.
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.
When should I stop watering before harvesting?
Stop Watering 1-3 Days Before Harvest – After flushing, in the final days of harvest, you can further stress your plants by stopping watering. You want to allow the plant to start to wilt just a small amount, because then the plant “thinks” it is dying and as a last-ditch effort, it will increase resin development.
Can you dig potatoes before they have flowered?

How many potatoes do you get from a plant?
A healthy potato plant can produce between 5 – 10 potatoes. A rough gauge of potato plant yield is generally 10 pounds of potatoes harvested per 1 – 2 pounds of seed potatoes planted. However, per-plant yield will depend on the variety and growing conditions.
Can you dig potatoes before they have flowered?
