Collection: fertilizers for Foliar Feeding

What is Foliar Feeding?

Foliar feeding addresses the immediate needs of a growing plant by spraying water-soluble fertilizers onto the leaf surface of the plants. Plants take up nutrients through their leaves and stems, using stomata–little openings similar to the pores of our skin, absorbing foliar sprays 20 x faster than soil-applied nutrients. Foliar feeding can also be timed to encourage and/or enhance critical points in the plant’s growth cycle, such as rapid growth phases or flowering, fruiting and seed formation.

Tips for Foliar Feeding

Foliar feeding should not be done in the heat of the day. Leaf stomata close at temperatures above 85°F.
Best done in the early hours of the day, because spraying in the evening may encourage powdery mildew.
If using a micronized fertilizer, be sure that it is fully dissolved before spraying. Less soluble powders may also need frequent mixing during spraying.
