Liquid and Foliar Fertilizer

Here is a number of liquid and foliar fertilizers to use as an alternative to our own range of liquid products. Foliar fertilizers are sprayed onto the leaves of plants early in the morning or late at night when the temperature is at its lowest to be absorbed by the plants through the stomata. This method is very popular to fix temporary deficiencies in plants due to the immediate availability of the plant food, and also to boost an already healthy plants performance. Liquid fertilizers are also used in irrigation systems and hydroponic growing systems. Please read the labels to see which purpose each fertilizer is used for, not all liquid fertilizers are suitable for the same things.
