Fertilizers & Amendments
Fertilizer injectors and a selection of New England-made fertilizers for nourishing seedlings. Our selection of fertilizers includes OMRI-listed organic fertilizers. Nutrient percentage profiles are listed in the order N-P-K: nitrogen (N) is associated with vegetative growth; phosphorus (P) with reproductive (flower, fruit, seed), and root growth; and potassium (K) with disease resistance, root, tuber and stem growth, and protein synthesis. In addition, many other minerals and microorganisms present in these fertilizers make an important contribution to plant health and the nutritional value of your crops.
