raised garden-concrete staining?
I'm planning to put two 2x12 ft. raised beds on my large conrete slab in the backyard. I noticed a post from someone that mentioned a raised bed will stain the concrete. I live in military housing and I have to leave the place in the same condition that I received it (no 12 ft. concrete stains). Has anyone removed a raised bed off of concrete and had trouble removing the stains? Thanks!
