I grew outdoors O. Haze and one of my Peak19 crosses with only the following slow release food. Had 7' trees with excellent yields. 3 gal. pots, custom potting soil, one 2 gph emitter to each pot run for 2 hours off my drip irrigation system. With the exception of the gusty winds I had no maintenance or problems.
I buy Polyon in a 25 lb. bag for about $53. Unlike Osmocote, its release is controlled not only by moisture but temps. Higher the soil temps, faster the release which is in perfect sync with the life cycle of the plant.
BTW, don't feed the troll.
