Great, as promissed
I treated my summer stressed lawn with 3 applications over 45 days and results were impressive. Application was easy with a backpack pump sprayer using a fan type nozzle. Directions are very easy to follow.
I'm going to use it on my lawn.
Easy to mix and apply. Results came quickly. Second buy for me.
The product was easy to mix and use. I used a backpack sprayer with a 4 gal. capacity. I cut the grass, watered it, and applied the nitrogen 24 hours later. I started to notice a difference on the 3rd day and the Greening up process is improving with each passing day. I live in the San Joaquin Valley in CA, so usually no rain after Spring until late Fall.
