Title: Soil amendments
Those of us who grow cacti and succulents need something to loosen up the soil and won’t break down over time (like peat or coir).  Those in the western states use pumice (not too many volcanoes here in Wisconsin – the only thing erupting is our state capitol!).  Other people use fired ceramic products like Oil-Dry, Stall-Dry or similar, but the consistency of those products seems to vary.  The chicken grit I obtain here (have to travel a ways from the city to the local Farm/Fleet store) is crushed granite (I’d stay away from products sometimes called “decomposed granite”), about the size of cat litter and works fine for me, although I only use it for potted plants.

Sand and gravel can be used, but again, the grain size is very important.  Use beach or play box sand (both smooth, round particle size) in our clay soil and you get cement!  Better to use a product variously known as builders sand, sharp sand or torpedo sand because of it’s sharp or angular particle size.

I've heard of chicken grit used to lighten heavy soils...how do you use it? Do you get it from feed stores? Does it degrade over time?
