Organic raised garden bed on top of pre-emergent?
I bought a 4'x4' composite raised bed to grow an organic vegetable garden in our backyard. But it just occurred to me that I previously treated our whole backyard with Scott's TurfBuilder with Halts Crabgrass Control in late March. Will this interfere with the veggies? The area where we are setting up the bed is pretty much a bare patch without grass anyway - dry clay soil. Would I need to put landscape fabric down or anything for protection under the added soil/mulch mixture?
