Once® Season-Long Plant Food (15-9-12)

Our special 15-9-12 NPK formula promotes vigorous flowering and overall plant health for up to 6 months—indoors or out. With Once, your plants receive an ideal balance of nitrogen (N) for leaf growth, phosphorus (P) for root and flower development, and potassium (K) for overall plant performance. Each 3 lb package feeds 32 flowering plants or 200 sq ft, and each granule is coated with a unique resin that controls nutrient release evenly throughout the season. Cannot be shipped to CA.
