Where to buy pine bark fines
I went to the local Home Depot and they have what looks like pine bark fines, but consisting of 50% bark and 50% compost. Is that good enough? It was a Nature's Helper bag. Also, is there any way to incorporate enough fertilizer into the 5:1:1 or gritty mixes that can be taken up directly by the plant roots? Watering with a weak fertilizer every day will take too much time and is infeasible with a hose. Can I just put blood and bone meal and greensand into the mix for the nutrients, along with the lime/gypsum/trace fertilizers?
