Potato advice that I've read says to not harvest all of the potatoes at once and that they would keep well in the ground for awhile. I went to dig up a few more potatoes and discovered that the fire ants were eating them, so I had to dig up most of them before they were all destroyed. Several of the plants are not ready, as evidenced by the tiny potatoes about the size of marbles. I thought ants were pretty harmless in the garden; other than biting me, I thought they pretty much left the plants alone, but I guess I was wrong. I had to throw several potatoes into the compost pile because there were little holes drilled all over them and ants coming and going. Grrr.
