Stop watering potatoes after the foliage turns yellow and begins to die off. This will allow the potatoes to mature to the right stage before harvesting. If you keep watering, the potatoes may mature and then rot in the ground before you dig them up.
How do you know when to stop watering potatoes?
Stop watering your potato plants about 2-3 weeks before harvest, or when you first see the foliage on the plants starting to turn yellow. Make sure to harvest your potatoes on a dry day when the soil is dry—harvesting potatoes when wet or damp can cause the potatoes to rot more easily in storage.

Do you stop watering potatoes when they flower?
Do not stop watering your potato plants during the flowering stage. This could cause a very poor potato harvest, so it is important to time your watering cessation properly.
