INDOOR FEEDING: 1/4 teaspoon of fertilizer per gallon of water with every watering or 1/2 teaspoon of fertilizer per gallon of water every other week. In high light conditions, you can double the above rates, which will create vigorous growth.

OUTDOOR FEEDING: Annuals, perennials, vegetables, and roses can be fed at a rate of 1 tablespoon of fertilizer per gallon of water; applied every 7-10 days. They key is to saturate the root zone with each fertilizer application, as most nutrients are absorbed through the roots for the plant to use.
