Welcome to ProLong® Professional Horticulture

We understand the importance of dependable consistent performance and quality, that’s why the ProLong® brand offers field proven recipes that have been used and trusted by growers for over 10 years. Our proprietary recipes provide the release curves demanded by today’s Horticultural growers.

The quality of our blends is based on the POLYON® technology. POLYON® controlled-release fertilizer with its trademarked green color is backed by years of research, and for decades has been the market leader in the turf and ornamental markets. The key to its performance is the Reactive Layers Coating technology which meters out nutrients via diffusion, regulated by soil temperature and coating thickness.
