Polyon® is a controlled-release turf fertilizer. The key to the consistent, gradual release of a Polyon® fertilizer is in the exclusive polymer membrane that coats each granule. Nitrogen is released gradually and consistently via temperature-controlled diffusion and it is not affected by moisture. The controlled release of nutrients helps to achieve a green, healthy lawn for up to seven months. And, because nutrients are released gradually throughout the growth cycle, there is less nutrient loss to the environment.


  • Lasts 12 to 14 weeks.
  • Abundant rainfall or watering will not affect the effectiveness of the fertilizer.
  • Diffusion of the product is temperature-controlled (soil and climate).
  • Does not scorch grass or plants.
