I'm expanding veggie garden I will have 2"x12"x22 boards buried about 4" in the ground . Also adding a 2nd plot about half the size. Then another location for chayote squash I'm in zone 8b Ponchatoula Louisiana. Going to try many heirloom and foreign veggies.Of course flowers for hummingbirds and butterflies and blooms for pollinaters..If the weather cooperates , I'll get to work
