Thanks Eric! That is actually some of my topsoil that I set aside from some building projects - pretty high clay content, but also a fair bit of rottted wood in there as well from roots/stumps. Good eye!
Probably fairly acidic, so maybe I should have raked in some lime. Will mulch with some compost - that might help.
Planted out with onions, Brussels, cabbage, broccoli, and cauliflower.
