This blend of lawn fertilizer is ideal for all lawn types. It is also a great stress blend during the summer months for all lawn types. It contains slow-release nitrogen which also will prevent nitrogen burn.
Once your application is applied and watered in, expect 7-14 days to notice a difference. As the nutrients begin to work, you will notice the lawn growing and darkening up in color.
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.
Fertilizer with iron can stain hard surfaces, so always sweep/blow stray granules off immediately. Do not wash it off with water.
Emerald feeds slowly and steadily for up to 6-8 weeks thanks to the 45% slow-release nitrogen. We recommend re-applying fertilizer at 6 weeks to allow some overlap.

"Very happy with the usage of Emerald 10-0-20 fertilizer. We have had near drought conditions but our municipality has allowed sprinkler usage. Some burned out spots due to lack of water, but overall the lawn continues to look great!"
"I ordered this fertilizer to keep up with nutrients for my small yard. I didn't over water the grass, followed the instructions but it seems it slightly burnt the yard in certain areas. To be honest the yard looked better before the fertilizer was spread. Nothing i can do now to correct it. Little disappointed in the product."
"Amazing products. Will never use any other product on the market."
