New to raised bed gardening, worried about chemicals in the soil
I am planning on constructing a raised bed in my backyard for some summer vegetables. I have done a raised bed before, but it was not under soil that had previously been treated by a chem lawn service. Of course, I am planning on adding organic soil to the bed, but am worried about drainage from other areas in the yard and chemicals that are currently in the soil where I would be placing the raised bed. Has anyone else dealt with this problem?
