I don’t think I’ve ever posted about potatoes. If I have, it has been a while. The basic spacing of 1, 4, 9, and 16 in the SFG system is excellent, but with potatoes, I learned to change that up. Potatoes are planted 5 per square, and I always make sure each seed has at least two eyes in them. I do not hill. I do not let them scab over before putting them in soil. I just bury them 7-8 inches deep, cover, and start watering. In about 5 weeks they break the surface. I’ve grown potatoes in grow bags before, but I’ve never been able to match the yield than I can when planted in the square foot gardens. The soil really makes a difference. How much can you expect? I always harvest 5-7 pounds of red pontiacs every year. And the taste.
