Potatoes are typically ready for harvest approximately 10 weeks after seed potatoes are first planted. It is best to harvest potatoes during dry weather conditions. It is important to harvest the entire crop by the time the potato vines die to prevent underground rotting.
Potatoes grow best in moist loose soil. It is important for growers to keep the plant bases lightly covered with soil at all times, as this will prevent parching of the potatoes. The best time to plant seed potatoes is within 2 weeks following the final spring frost. Planting the vegetables in acidic soil helps to prevent potato scabs and damage that can occur from soils with high PH balances.
