homemade potting soil inquiry
I have plenty of horse manure which I can compost. When it's "well-rotted" (composted) I was considering following the instructions/ingredients on this youtube video (link included below) to make me a big batch of potting soil for containers growing flowers this spring. I'd have to buy some stuff, the perlite, the peat moss, etc. I have 12 half-barrel size containers that hold about 8 inches of dirt in each, plus a planter box on a deck that measures about 3 feet wide and 6 feet long and has a depth of about 8 inches for dirt. Seems like that might add up money-wise pretty quickly. I haven't priced peat moss but I'll bet its not cheap. Plus, what about instead of the perlite I maybe use pine bark fines if I can get them? Would that be better or not necessarily? Any comments appreciated.
