Yard Mastery Double Dark 16-0-0 Granular Lawn Fertilizer with 6% Iron and Bio-Nite - 18lb Bag Covers 6,000 sq ft - Green Up Your Lawn Without Excess Growth - Apply Year Round

The media could not be loaded. Watch the video and be inspired. I highly recommend it. I use this product year-round here in South Florida, and I weed and feed seven days apart for the best results on my lawn.

This product recommended by a soil test company. The lawn I work with needed potassium @ iron. This product fulfilled the needs I needed to improve lawn quality.

I have a fertilizer company, and, I used this a week after their weed and feed application. Two weeks later, the yard turned dark green, almost blue! Quite a contrast from the neighbor's yard in the background! I love it!

Thanks Yard mastery with my stressed out lawn!!

As granular, it takes a wk or so to work. I probably need a second application. My son swears by the product, but as a liquid. Looking better after 10 days.

I have been using this for a little over a year. I saw someone use it on Tik Tok, and I figured that I would give it a try. I am impressed beyond measure! I keep a 45-pound bag in my garage. All of my neighbor's yards have been burned by the heat, and my grass looks so dark that you might think that it is artificial. Ironically, they are paying companies to fertilize their yards. I know that I should be ashamed for putting this on Amazon, but I feel kind of good that I have been upkeeping my yard on my own. I was ordering my tri-monthly bag and remembered that I needed to leave a review. ( i have Zorro Zoysia grass.) I hope this review helps someone else. Have a great 4th July week!

My lawn was looking okay, but I wanted to be darker green and be outstanding. Unfortunately, this product only kinda worked. It worked more like a regular fertilizer. It made my lawn grow like crazy, but the green was about the same. The extra cutting was not fun.

Don’t even consider the other guys, Yard Mastery is hands down by far the best thing you can put in your yard. I seen a random guy on tiktok talking about this so figured I’d give em a shot. Fall and spring I throw down the double dark and for the unbearable Houston summer heat, I lay the drought one. Since switching from the big guys to Yard Mastery, I’ll gladly put my grass up against anyone in my neighborhood. Coworkers now use it after seeing the magic it’s done to my grass.
