Is it time to introduce the use of gypsum in conjunction with clay? I have known several people who were gardeners that swore by it. Especially it's application on clay over a period of years. I have used it off and on, but truthfully I was unable to notice that it altered the clay to a more malleable state. However, my use has been sporadic. It probably has never been over a long enough time frame where it's supposed to effect things.
