Feeding chart & mixing calculator
Our official feeding program — the same chart we hand out at the store in Nevada City, CA 95959. All rates are per gallon of water. 15 ml = 1 tbsp · 5 ml = 1 tsp.
How to read these minimum application rate suggestions
The low end of each range is our minimum application rate suggestion — enough to feed your plants well. Move up within the range for heavy feeders, hungry soil, or peak season. Section A alone gives you excellent results; add Section B when you want to push further.
All rates are per gallon of water. 15 ml = 1 tbsp · 5 ml = 1 tsp.
