Question: how do u know when your potatoes are ready to harvest?
Answer: When to Harvest Potatoes For mature potatoes, wait 2 to 3 weeks after the plant's foliage has died back. The tops of the plants need to have completely died before you begin harvesting. Cut browning foliage to the ground and wait 10 to 14 days before harvesting to allow the potatoes to develop a thick enough skin.
