For the last couple of years we have been planting potatoes in the summer to harvest in the fall. Those that we plant in February and harvest in May do not keep until the fall so it is nice to be able to get two crops a year. It is tricky to get them to grow in the summer as it is too hot for them. We make sure the soil is moist before we plant, then water the crop as little as possible until they emerge. Too much water and the seed potatoes rot in the ground.
