Got Questions?
Frequently Asked.
Everything you need to know before you start your daily routine.
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.

Reviews
Very happy with the usage
"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!"
Damaged grass
"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."

Q&A
- Does the Emerald contain any weed killer qualities? I have some clover, not much but would like to know if I will have to apply weed killer separately?
- The 20-0-10 Almighty Fertilizer does not contain weed control. Post emergent weed control products would need to be used separately.
- my lawn in the summer gets sun all day long will this work on my lawn?
- This is a great fertilizer choice to use of cool season grass types over the summer season.
- Does it work on zenith zoysia grass
- 10-0-20 is a great product to use on Zoysia sod as a winterizer fertilizer. During the summer growing season, I would recommend using the 20-0-10 Almighty for zoysia grass.
- How long before / after mowing should Emerald be applied?
- Emerald can be applied right after mowing. If you are planning to apply before mowing, make sure the product is watered in very well first and then mow once the lawn is dry.
- Hello, Does this product burn the grass?
- This product can burn the grass if it is over applied. We recommend applying this product at 4-5 lbs. per 1000 sq. ft. Space out all fertilizer applications by 6-8 weeks.
