I had given up on late plantings of summer squash due to pickle worms. Of course I usually planted around the first of August. This year some the vines ran over into the corn patch and a few matured there. Turned them down just before Labor day. Volunteers came up and with no care at all have developed squash. The pickle worms have gone back to Florida so they are pretty nice squash. So next late August/ early September guess what I am planting. These are volunteers (F2) of the cultivar Horn of Plenty.
