“Organic gardeners use fertilizers like seasonings. They add the finishing touch that brings out the very best in plants”  – Rodale’s all new Encylcopedia of Organic Gardening


Chemical fertilizers feed the plant and not the soil.  In time the soil becomes more and more stripped of organic matter requiring more and more chemical fertilizers. Organic fertilizers feed the soil as well as the plant providing a food source for soil micororganisms and earth worms that condition the soil bringing in oxygen and other needed nutrients. When buying organic fertilizers, don’t always trust that it doesn’t contain chemical fertilizers.  Read the labels. Be wary of products labeled organic that have an NPK ratio that adds up to more than 15.  NPK stands for Nitrogen, Phosphorus, and Potassium.
