"If you get it for free, then it's dirt. If you have to pay for it, it's soil" David McLean I'm curious about what sort of potting mixes everyone is using. Mine is very simple - 2 parts pine fines to 1 part Bushel Stop potting soil. The Bushel Stop soil is approximately: half top soil, one-quarter sand, and one-quarter crushed pine bark. I've had very good success - better than 90% - with gray wood Croton cuttings and the mistbed.
