Fred, In your raised beds, do you put your soil mix in there or, do you put your plants in pots? Are these your display beds or where you "line out" your plants to sale?
I'm having a terrible time with tree roots getting into my pots. I raise all of mine in pots. I'm seriously considering building some raised beds like yours. Do you put plywood down for the bottom? I'd guess whatever goes on the bottom is treated?? Thanks Mona
