Scotts Halts Crabgrass preventer
We use Scotts lawn products every year including this Scotts Halts Crabgrass preventer. We don’t have any crabgrass growing in our yard. It’s easy to apply to your lawn with a spreader. It works and we definitely recommend it.

Crabgrass Preventer
I was glad to see this product available on-line. Our local hardware stores and even the big box stores did not have this in stock when I needed to apply the weed preventer. I'm hoping this will make an impact on the crabgrass this year.

All Scott’s products for my yard.
I’ve been using this product for three years now and love the results. I also use other Scott’s products and My grown children call my yard, Little Augusta! I have 1.5 acres and after letting 2 different companies try for 5 years, (1 a national brand the other a local service), I had to take it back over myself. 31 years in my house and it just keeps getting better!

What I needed!
In Missouri, applied in August for henbit and oxalis, and again in April for crabgrass with a Classic Drop spreader on a Zoysia lawn with some bermuda invading. I finally realized I had been cutting my grass too short with a new mower and that was the reason why I was seeing more weeds every season. Both neighbors let their grass grow very tall and then mow it down really short. Problem is, their lawns are full of crabgrass by late summer and so all those seeds end up everywhere, especially along yard margins and traffic areas. This product substantially reduced the amount of crabgrass and henbit in my lawn, to the point where I could just pull out, by hand, what few there were. The oxalis does not seem to be getting any worse, and, after adjusting the mower, appears to be getting mostly choked out by the desired grass plants. Make sure to apply just before rain is forecast and make sure to overlap passes as recommended on the packaging and remember that aerating, dethatching, or anything else that disturbs the soil, will definitely reduce the effectiveness of the product. I had previously had large rafts of crabgrass by late summers, that would choke out the bermuda, and then die off in winter to leave patches of bare soil, but no more since using this product.

Halts has never failed me
Have used Halts for over 6 years now. Always applied in early spring once grass is out. My neighbor had crabgrass so started applying it to his yard. Since then, haven't seen any in our yards. Never watered it in and would apply when a good rain was coming in 4 to 5 days.

Awesome pre-emergent
Fired worthless TruGreen (3 yrs ago) after 22 years and startes doing my own lawn. Scotts grassy weed preventer stops 99% of Poa annua grass (and others) when used in Fall and again in Spring. This treatment along with Scotts Weed and Feed keep my bermuda lawn looking like Augusta National Golf Course.

It works great if used routinely
Ive been using this product 4yrs plus. I used to have a POA Annua infestation every year prior to that until I found this pre-emergent. Its not a miracle preemergent, but with routine use and manually pulling the poa that does manage to sprout, I reduced the infestation at least 99%. Now I can count on my hand the number of POA that sprout every year, its very minimal. I think it does a great job if used on a regular basis and given time to work.
