Default Re: How often should I fertilize???

I'm in zone 9b/10a. I fertilize once per month during the active growing season. Here are the rates I'm using:

Very Young Plants, TC's: 1/4 teaspoon per gallon of water every watering.
Young Plant in 2 gallon pot: 2 tablespoons per month.
Plant (not juvenile) in 10 to 20 gallon pot: 1/4 cup per month.
Plant in ground with significant root space: 3/4 cup per month.

Here I'm referring to the blueish crystals with one of these formulas: 15-5-30, 15-10-30 Urea Free, and 20-5-30.

When fertilizing, only use enough water to get to the roots -- you don't want to have a portion of your fertilizer to run out the bottom of the pot.
