How much fertilizer to use?
I'm just starting a container garden here in Oaxaca, at 6000 ft altitude and at the end of the rainy season. My compost pile has just been started, so I have to use chemical fertilizers until I have compost. I bought a bag labeled 15-8-20 but I have no idea how much I am supposed to apply to each container (ceramic pots from 12" to 36" wide and deep, and some homemade wood containers) nor how often I should apply. Can someone give me some advise? Thanks.
