where to buy sand?
Can anybody tell me where I can buy sand to add to soil? I live in Montgomery County, MD. I have seen the sand I want called, variously, sharp, silica, or mason's sand. All I could find at Home Depot was playground sand, and when I asked a staffer at a plant store if they carried sand to add to clay soil, she just gave me a strange, bewildered look. I have a site that gets a brutally large amount of sun and is mostly sheltered from rain, but all the drought-tolerant plants I want to put in there (herbs, etc.) need good drainage. I know I'm probably going to need to add a lot of sand, but it's a very small patch of ground.
