Square foot gardening: potatoes

The normal spacing of 1,4, 9, 16 is a little different for potatoes. I’ve been asked how much to expect from a single square of potatoes. This is what I got when I harvested last week. Eight pounds! For the past 3 years I’ve tried without much success to plant these in grow bags. Much has been written about how to do this, and some have reported much success. I’ve never been able to do it. I have, however, always been able to grow potatoes in my SFG soil. Because they take 3-1/2 months from seed to harvest, I thought switching to grow bags would give me the same yield and save room in the SFG beds. It didn’t. I don’t even hill the potato seed. I simply put them in the soil about 6 inches deep, cover with soil, and start watering. Red pontiac’s. They are so good. I’m going to attempt growing some right now in the hope that I can have baby new potatoes for the winter. 

Potatoes in the square foot garden

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.
