Not worth it. I was so determined that I wasn't going to have rust stains on my concrete that I used a blower to blow everything off and then went over it all with a push broom. Then I used a high pressure hose to spray off the sidewalk while hoping that any fertilizer that I might have missed would be washed away before causing stains. Nope! Wrong!!! My beautiful concrete is ruined. It's like the fertilizer immediately bonded to the concrete. Again, it didn't do much good to blow off the dry concrete and then sweep it. I tried Goof Off Rust and Stain Remover that didn't do anything to the rust but left nice white spots are to highlight the rust. I will NEVER use this fertilizer again. If you want green grass without all the problems of rust stains then look into using epsom salt. Cheaper and no rust. I will use other Scotts fertilizers, just not this one.

Went to apply Green Max several weeks ago. AFter filling the spreader and doing the front lawn I noticed that no very little fertilizer was being applied. It looks like Green Max absorbed moisture as soon as exposed to air and ended up clogging the spreader. I do not recommend this product!!!! Ended up disposing the remainder of Green Max.

[This review was collected as part of a promotion.] This product has made a total change in my lawn. I used it on my lawn but some parts i didn't put none on so i could see if i could see a difference an to my surprise you can see a big difference.its green where i put it on my lawn an less green where i didn't put it. This product is awesome an i would definitely purchase it again an i highly recommend this product.thank you scotts for this wonderful product.

I should have read earlier reviews. Any granules left unswept on the driveway or walks will leave horrible RUST stains. The only thing that will take them out is a special concrete-rust removal powder that can only be found on the internet. By the time I'm done, I'll have wasted over $50 (if I don't run out) and a weekend scrubbing all of the rust away. Yes, it did make the grass a nice shade of green, but the time and effort to remove the stains negates all of that. This was one of my worst purchases ever.

I recently purchased a bag of Green Max fertiliaer and have been delighted with the results. In only a couple of days my grass was a vibrant green and really lush. This is the first fertilizer I have found that can do this in the heat of Texas summers. We have the best looking grass in the neighborhood. THANKS SCOTTS!!

Now in my 36th gardening season and have always had burning problems with the second lawn fertilization because of high ambient temperatures. So I decided to try Green Max for the first time despite the price. There was no burning/browning issue and my lawn is not only green but also LUSH. Wow!

[This review was collected as part of a promotion.] I was given this product to try and report on. I used and was very happy with the results. It seemed to show results in about three days. It seemed to be greener on my lawn than the neighbors. I recommend it.

This is stuff has my lawn beautiful. No clumping in the bag and I live in Louisiana where humidity is high. But I dropped the bag on the ground a couple of times just in case. Now everyone in the neighborhood has been stopping to see what I use on my lawn. I have Bermuda grass so don't be afraid to try it!! Try not to get any on sidewalks or drive way because it will stain!!!

Spread some Greenmax using spreader. Used broom & blower to sweep off concrete and deck, but a hard rainstorm washed some into pool and on other concrete surfaces. Now I have multiple stains and blotches. I see from the reviews I'm not alone. Like the others, I'm out money and time, plus worrying whether the stains are ever going to come up.

Although the instructions say the grass can be wet or dry, there is nothing mentioned about the horrible rust staining that this product causes to wet surfaces other than grass. I spread Green Max during a light rain. I tried to sweep off the driveway and such but the damage was done. I have horrible rust stains on my driveway, sidewalk, landscape rocks, house siding, and pool deck. I have spent several hours and dollars trying different methods to remove the stains. The stains have not faded at all. Not the smallest bit. Even if my lawn were to turn into the greenest green, nobody would notice it due to the ugly rust stains covering everything. The rust stains even cover the street and gutters from where the rain washed it away. It's a good, permanent reminder of where the runoff goes.
