Too much water can cause rotting while too little water can affect development. It's important not to underwater or overwater young potato plants. If they receive the wrong amount of water in the early stages, the potatoes might become misshapen or not develop well.
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.
Should you water potatoes every day?
Unlike other crops that may need an opportunity to dry out some, potatoes need moist soil. They are a cool weather crop that enjoys springlike weather; this means plenty of rain showers! Ensure that the plants receive between 1 and 2 inches of water per week so that the plants always have dampened soil.
When should I stop watering my 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.
How much water is too much for potatoes?
“Potato tubers contain no less than 80 per cent water; the rule of thumb is that the potato crop needs an inch of water per week to produce a good quality crop.”
