Q.Drainage of a Box Garden
I plan to put my box garden within an existing flower garden that has black plastic down and then 2- to 3-inch river rock as a ground cover. Should I scrape this all away down to the existing soil or just put the box over top of the rock?

As long as your garden beds are at least 8 inches deep, it should be fine to set over the stones. I would puncture the black plastic in several places to make sure that there is drainage.
