I was wondering if I’m getting this wrong with my technique and soil mix? I till the area I want to plant in first breaking up the ground and removing some dirt. I think mix in compost, pine bark much and soil conditioner into the area with the natural soil. Then dig the hole to size then putting a little more compost, soil conditioner in mix then plant the maple. Basically I’m trying to prepare the area around my potting hole too. Can I just mix pine bark mulch, soil conditioner, compost and then using store bought potting soil for planting maples in pots? It just has to drain right?
