My son and his grandfather built this for me. It came towards the end of summer, so I didn't plant anything in it this year, but I'm itching to do so in the spring! I want to make this last as long as I can...it's made with treated wood, but I still want to protect those boxes somehow. I know I could put pots in them, but I would much rather plant within the boxes, I just think it would look nicer (round pot in a square hole? Nah...)
Is there anything I can coat the inside with? My hubby wondered about tar (like we've used to seal water tanks with...roofing tar...but would need to drill drainage holes) or I also wondered about that spray-in bedliner stuff for trucks. Or just leave it...or add a second wall of plywood...I don't know.
Hoped someone here would have some suggestions! I love this thing, and want to take care of it, but still USE it!
