Say i wanted to move the medical operation to the garden next to vegetables and such to save on power. The soil is on the clayish side but damn good stuff with a ton of worms. Can i just loosen the soil about a foot down and mix a bunch of store bought compost into it. Or would i need anything else? Id like to only spend money if i have to. The climate is definitely on the wet side if that matters. The compost is called black forest and it says its organic. I do not have anything to test ph with.
