grit in the U.S.?
Hello, every time I ask for grit at nursery centers I get blank stares, even when I describe it as bigger than sand, smaller than pea gravel. Is there another name for what I am looking for here in the U.S.? And/or, suggestions for what to use to lighten up my very heavy New England clay soil that is not perlite or vermiculite? I add lots of organic matter, of course, but I don't produce enough kitchen waste to have a good source of compost. Many thanks for any ideas!
