Potatoes need 1 to 2 inches of water a week. Too much water right after planting and not enough as the potatoes begin to form can cause them to become misshapen. Stop watering when the foliage begins to turn yellow and die off.
How often do you water newly planted potatoes?
In the absence of sufficient rainfall, a consistent watering schedule of once every four to five days is generally ideal for a young plant. Increase the frequency to once every two to three days when tubers form, which happens about the same time the plant flowers, to encourage uniform potatoes.
When should you water potatoes?
Potato plants need 1 inch of water per week to reach their maximum potential. Without water, the potatoes will not reach full size. Additionally, they may be deformed or have a hard texture. After the blossoms appear on potato plants, increase the water supply to 1 1/2 inches of water per week.
