I have 25+ used large black plastic nursery-style pots full of used potting soil. The soil could be refreshed with osmacote or any other favorite fertilizer. I also have 75+/- assorted sizes used empty black plastic nursery-style pots. These will need to be picked up soon in West Blocton, Bibb County. Would love to trade for a few clay-colored window boxes or 4-6" square black or clay-colored pots. Bring a truck and load 'em up
