How often do potatoes need watering?
Potato plants need 1 to 2 inches of water weekly between rainfall and irrigation. Water the plants every few days when you don't receive enough rainfall to meet those requirements.
Can you overwater potatoes?
Depending on the growing stage, overwatering can have different effects. Watering too much after planting and not enough while the new tubers are forming can lead to misshapen potatoes. Overwatering after the plants die back can cause the underground potatoes to rot.
Do you keep 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.
