Promix and Controlled release fertilizers, help please
I know this has been addressed in another thread to some extent, but just to clarify, if I use the Promix, would I still add some Controlled release ferts at the time of planting? I'm still not sure if I'll be making the 5-1--1 mix or the Promix. It's going to be determined by energy required and if the pine bark mulch I ordered is what ii need for Al's mix. I know Promix has everything in it, but just wondered about the CRF's, understanding that I don't use organics in containers. I also use a weak water soluble fertilizer when watering.
