We just had our first frost last week and I dug up my potatoes grown in a tire stack. I was disappointed to find only 6 potatoes. I planted 3 seed potatoes in the initial tire, and partially covered the greens, as they appeared to a final height of 5 tires. Any suggestions as to what went wrong. It would be helpful for next years attempt. Thanks.
I don't know about growing potatoes in the tires, but I do know that certain kinds of fertilizer encourage a lot of top growth on your potatoes, and so they do not grow as many potatoes. Perhaps this is what happened to your potatoes. Also, sometimes potatoes just do this -- produce a couple of really big potatoes, and not a whole bunch. It may have to do with the kind of potato you planted as well. Have a talk with other gardeners in S'toon, and see what is a good type of potato. I suspect, since you didn't have an abundance of little potatoes, that it was the amount of fertilizer or type of potting soil.
