Why are foliar sprays used?
Foliar sprays are nutrient solutions that are highly diluted and lightly sprayed on the plants. Plants are able to take in these nutrients through the leaves. Foliar feeding of plants is the frosting on the High Brix gardens’ cake. Well made foliar sprays can have a tremendous impact in raising brix readings in plants. Foliar sprays are also used to direct a plant in which way it should grow. Plants can be told to grow vegetatively or to grow reproductively. A foliar spray that makes vegetative growth (new leaves) is great for spinach but entirely unsuited for tomatoes.
