I’m trying to figure out how much soil is needed to fill 12 15 gal plastic pots with potting soil. Any help would be greatly appreciated.
maybe 3 big bags, that’s what i would get
Do you really want to start off that BIG?
5 gal = 20 l 15gal = 60l 60l x12 = 720l of soil
I would buy 740-760 L just to be safe
How about roughly 25 cubic feet. That’s assuming true 15 gallon pots full and you’re not cutting with perlite or anything.
A dozen 15-gallon pots is gonna be an orchard! Go big or go home
