Foliar fertilization

From BonsaiWIKI

Foliar fertilization is the application of fertilizer to the foliage of a plant. Some nutrients are absorbed quickly through the leaves and distributed throughout the plant. Potassium is one that is absorbed well. Zinc applications Waxy and oily leaves can resist the entry of foliar fertilizer.

Nutrients are absorbed through the stomata, openings in the leaf surface. So, for absorption to occur, the stomata must be open. So, the ideal time to apply foliar fertilizer in a fine mist, in early morning, when the temperature is below 72 degrees Fahrenheit.
