MADE IN USA Quality really matters. Osmocote 14-14-14 controlled release fertilizer is engineered to help deliver bigger, greener plants. Only one application of fertilizer is needed for the season. This fertilizer is composed of water-soluble nutrients. The granular formula is coated with a film of plastic resin. This product, when applied, has a slow release effect of 3-4 months for annuals, perennials, and short term crops. This is based upon a 70 degree temperature so it will vary some with each application.
