I have a cotton bush that came up self sown three years ago. The frost cuts it off every winter and it re-shoots again in the spring. It is never watered or treated for pests. It has never had any of the heliothis caterpillers attack it although they attack my tomatoes at times. I picked 16 bowls from it a day or so ago. It has still got some unriped bowls as well. Everyyear it has been growing it produces cotton.
