liquid soil aerator? clay amendments, etc
I'm looking for a way to help out some of my beds. All this month's rain has really reminded me of how dense my soil is... it is so sticky that it ends up clinging to me and all my tools.... and dries so hard that I have to take a hammer to get it off my tools. I'm making a new bed and also fixing some areas that I'd like to have more "plantability"... and wondering if any of y'all have tried "liquid aerators". What are they?
I also read here about expanded shale... does anyone know where you can get this stuff in Austin?
I add compost and stuff, but I like the idea of more long-term help so I don't have to bucket in loads of compost every year.
