Stressing about drainage, building bed, etc.
I have a few layers of a lasagna garden going--cardboard, leaves, kitchen scraps, newspaper, more leaves--on top of my sandy soil on a lot that tends to flood (but not in the location I selected for the garden).
Should I dig down and turn over the soil beneath the lasagna layers?
Should I drill holes into the ground and fill them with gravel?
Should I put 4" Mel's mix on top, stir it up, then add more Mel's mix (this idea came from another Garden Webber -- thanks!)?
I'm hoping to make a longer-term plan here (synthetic lumber for boxes, at least 12" of depth) to avoid having to redo everything years from now. I'm new to gardening, and even though I realize many mistakes will be made, I don't want to screw up too badly.
Any other thoughts before I construct this baby this weekend? Thanks.
