Rated 5 out of 5 by from Best looking grass that I've ever had. I've been searching for years for something to make my lawn look acceptable to me. I've put many different weed killers, Crab grass control, Dandelion killer, Turf Builder with Halts you name it, I put it on the yard along with very good fertilizer that promoted grass seed growth, it was the same results every year. It seemed like a losing battle. Last year I went to Lowes and bought 2 bottles of Bayer Season Long weed control. It was less than a month after I used it that I noticed all the clover, stringy weeds growing close to the ground, Nut grass, dandelions, and other pesky weeds were gone. I went back to Lowes and bought 6 bottles for future use. I was afraid they might stop making it. Hope they dont, its the best thing on the Market.

Rated 5 out of 5 by from Dead weeds! I have a St Augustine lawn and have to be really careful what type of weed killers I use on it. I have had bad results in the past with other brands. Other brands have almost killed my St Augustine. Bayer Season long weed control has killed my weeds an not my lawn. Thank you Bayer Products!

Rated 4 out of 5 by from Easy to use. This product is easy to use, hook up to the hose & spray. My husband uses this every year a couple of times in the summer to control the weeds that would have taken over the lawn. He thinks it works very well & even uses on our daughters lawn & his brother's lawn.

Rated 4 out of 5 by from good producr Good product. I recommend setting aside a dedicated garden sprayer. Use according to directions but only use the product as a spot killer/control chemical. A little chemical goes a long way. Repeat as necessary when new weeds present themselves. Don't rinse and clean the dedicated garden sprayer since this the only product used with this sprayer. Dedicating a sprayer saves a lot of work and time in the long run.

Rated 5 out of 5 by from Works great This truly keeps the weeds away and kills the ones that are already in place. I wasn't sure how well it would work. I picked it up on a whim and was so happy to see that it lives up to the promises!

Rated 3 out of 5 by from OK Product worked well at the start but did not work as long as they say. I had weeds to deal with again in a month or so.

Rated 5 out of 5 by from Bayer Long Week ready to spray I believe this product is the best on the market; which I have tried many. I also, believe my yard is the best looking in the entire neighborhood, even in the hot (100+) days of summer. I will never use anything else on my yard.
