Need a Stronger Nitrogen Push?

If you want faster green-up and more top growth, consider our Almighty 20-0-10. It delivers double the nitrogen of Emerald 10-0-20 with 15% ammonium sulfate for instant color and 45% polymer-coated urea for weeks of steady feeding.

Frequently Asked Questions

Can I use this on St. Augustine or Centipede lawns?
Yes. Emerald is phosphorus-free and safe for both. For Centipede lawns, alternate with a lower-nitrogen product like NutriGreen 0‑0‑4 to avoid over-fertilization.

Will it stain my concrete or patio?
It may. Fertilizer with iron can stain hard surfaces, so always sweep/blow stray granules off immediately. Do not wash it off with water.

How long does it feed the lawn?
Emerald feeds slowly and steadily for up to 8 weeks thanks to the 45% slow-release nitrogen.
