Several experienced gardeners have told me and I have put into practive
over the last year the addition of gypsum to the soil to break up the
cement like soil we have here in southern California.    My beds are now
with the addition of compost and gypsum easily turnable and less claylike.
Bags of gypsum are available in gardening stores  and instructions
regarding application has been on the bag.
