My neighbor and I are in a bit competitive with our lawns; we water and cut the grass equally. During the extreme heat our lawns showed the distress. I applied Green Max and within days my lawn greened up while his stayed brown.

This product is hazardous to your concrete, tile, sidewalk, actually all none grass surfaces and should be used by professionals. Use at your own risk (.)

[This review was collected as part of a promotion.] Yes, this product works as advertised. My lawn was noticeably greener after just first day and a beautiful deep green after 5 days!

The GreenMax worked great. It greened my lawn up in just a few days and lasted approx. 7 weeks. I had to mow 2 times a week. I will use it again..Just be careful to sweep it off the concrete before it gets wet or it will leave an iron stain.

This product is fantastic. The extra iron gives you an extremely dark green color that will leave your neighbors wondering what they are doing wrong. This product will not disappoint. The attached picture is worth 1,000 words!!!

[This review was collected as part of a promotion.] Used the product last year and my lawn exploded with green very quickly. Just bought 2 more bags and will apply next week.

My yard was a show stopper last year. It was the envy of the neighborhood. I got so many compliments about how green my grass was. I just applied Max again this year and I know what results I will get again. So beautiful!

if you want the greenest lawn in the neighborhood, this is the product you want. Seems to last about 6 weeks so you'll need another dose or two during the summer

Very nice product with lots of iron. Be sure to quickly sweep/blow product off surfaces you don't want rust forming before water touches it. My yard is noticeably much greener even with way too much flooding rains after application.

I applied this product in early Spring and it was not affective against preventing Crabgrass as of today I have Crabgrass all over my front and backyards.
