One thing I'm loving about the trench method ... there's so much clay in my top soil that the heat is forming a crude Terracotta (see the orange in my pic). I've already tested that orange stuff; it is stable in water and holds its shape as a loose gravel which helps the porosity in my dense clay topsoil. I had been hauling in play sand to amend my potting soil. No need for that anymore, YAY!
