Rated 3 out of 5 by from Will it Workd I just bought a Scott's Elite Rotary Spreader and Halts® Crabgrass & Grassy Weed Preventer. The bag says, and website says, set it at 2 1/4. I've done that, very little product seems to be emerging. It's not clumpy and the spinners are spinning, but I'm skeptical. I watched a video for this exact product and in the video, it seems to broadcast copiously

Rated 3 out of 5 by from My accidental experiment I used this product and it didn't seem to work. However, I had an interesting incident with it. While using my spreader on a hill, it tipped briefly and spilled a decent chunk of material on the lawn. I scraped up what I could, but over time, what was left washed down the hill. Where the bulk of the product fell, the grass died. I wasn't surprised at that. But the picture shows what happened with the product that washed down the hill. The grass is green and weed free. Beautiful. The first pic is from about 8 weeks ago, second pic is today. What I conclude is, though applied according to directions, the application was not heavy enough. That's Scott's fault. My concern is that the directions "stretch" the application area beyond what is realistic to make the price seem more favorable? I'll use again next year, but at heavier rates.

Rated 3 out of 5 by from Hope this works Just finished application. Couldn't see too much coming out of my spreader. Setting was set at 2 1/4, just like the instructions said. Mabey this is pretty powerful? Any input is welcome!

Rated 3 out of 5 by from The product works ok Some of my crab grass and weeds have died off but not all. May have to try using it again.

Rated 3 out of 5 by from Decent on Moss I received this product to late in the year to test out its effectiveness on Crabgrass, so I gave it a shot on moss. I had some limited success with some of the moss turning brown but it didn’t destroy all of it. It could have been that I didn’t apply enough too.

Rated 3 out of 5 by from Can't See a Difference Yet I've been dealing with some medical problems, so my neighbor distributed the weed preventer. Since my injury, I have not been able to do much walking, but the backyard is small and I did do that area, over a few days. As of the weather now, it's too gosh darn cold to go out. I will update this IF I see a difference, but so far that is not the case.

Rated 3 out of 5 by from Crabgrass preventer I like this product for spring, before crabgrass can take root. In the fall it works well, but doesn't kill the grass.
Date published: 2017-12-15
Rated 3 out of 5 by from Wont know till the Spring! I only gave it 3 stars because I don't know yet if it really works. I put down the Scotts crabgrass preventer earlier this Fall and will wait to see how it does in containing and preventing the spread of the pesky crabgrass. I will follow up my review in the Spring of 2018.

Rated 3 out of 5 by from my weeds I applied this product yet have not seen any improvement in weed control. I realize that it may take time for this product to work but I was hoping to have seen improvements within a reasonable amount of time. I will keep waiting and hoping for improvement.

Rated 3 out of 5 by from So far so good 1st time using Halts. Have noticed the crab grass seems to be subsiding a bit. It is nov-dec in ALABAMA and the grass has gone dormant. Anyhow my hopes are high!
Date published: 2017-12-03
Rated 3 out of 5 by from It works, but could be better I apply this every year according to the directions. It helps but I still get crabgrass throughout the lawn. I know this product helps with the crabgrass since one year I went with a company to apply organic fertilizer for me and my lawn was overtaken by crabgrass by August. I went back to this product ever since to help control the crabgrass. I wish it was more effective where it was applied.

Rated 2 out of 5 by from This product wasn't it for my yard I bought this product because it's name is supposed to be the best. I bought 3 bags to cover front and back yard. I applied and I thought it worked my whole yatd was brown,but to my surprise I got even more weeds after 2 good rains of different weeds from before. I don't understand followed the directions on the bag. I choose this because I researched each weed I saw in my yard and they were on the back of the bag.

Rated 2 out of 5 by from Not effective. Third year of using this product. It has not eliminated or reduced the crabgrass

Rated 2 out of 5 by from Didn’t work for Poannua. Used this product for the last two years applying on Bermuda in South Carolina in November and February trying to eliminate Poaannua and it was completely ineffective and there is no crabgrass but the poannua is worse than ever. Won’t buy again.

Rated 2 out of 5 by from It works a little. Its not that effective or strong. Slows some growth.
Date published: 2022-04-04
Rated 2 out of 5 by from Not the best I live in phoenix, so Spring comes earlier some years. Bermuda lawn, not overseeded. Non-hybrid Bermuda grows when soil hits 65 degrees. For this reason, When it was forecasted to be in the upper 80's, lows around 50, I applied this product. Then, it cooled down, so I applied it again 4 weeks later, same temperature range. Although the crabgrass was prevented to some degree, I find myself pulling random spots out daily. I do not remember the brand of pre-emergent I used last year, but wish I could as it was 100% effective. It was not a household name. I had two problem spots in my yard in previous years, and made sure to cover them this year before soil temperature reached 58 degrees with Scotts. There are better products, but supply chain issues limited my options. The product isn't perfect. Also, i don't think it did anything to prevent clovers or sedge, but I have no way of knowing if I would have had more trouble had I not applied this product.

Rated 2 out of 5 by from Hope it works on crabgrass, failed on winter weeds I actually was on the ball in getting the Halts down as a pre-emergent in the fall. I was pleased I could finally stop the Chickweed, Henbit and Poa Anna that have plagued me for many seasons. Well that was an epic fail. I think my yard it worse this year and yes I got it down in time in the fall. I just reapplied 2 weeks ago for crabgrass and I swear the Rest of the weeds grew taller over night just to spite me... LOL! So fingers crossed this at least works for crab grass, cause so far I have flushed 2 bags down the to use it as a pre-emergence for winter weeds. If this site allows updates I will update regarding its crabgrass fighting abilities when I see later this spring.

Rated 2 out of 5 by from Killed my grass I dont recommed for Kentucky blue grass. It killed everything in the area I put it down in except the crab grass:-(

Rated 2 out of 5 by from Sub par product I bought this product early March and applied the second week of March in New England so well before crabgrass germinates. I followed all the directions and this weekend I have crabgrass sprouting up and other grass like weeds that I have never had before. There is definitely less crabgrass then I had last year but still much more then I had expected
Date published: 2020-05-04
Rated 2 out of 5 by from How to use I would be nice to have a more thorough explanation of how to apply. Not just on dry no watering. We have rain almost daily and would be nice to know if I put it on when the lawn is dry but it rains an hour later am I ok. Will just have to take my chances

Rated 2 out of 5 by from Short Life Customer service advised the product effectiveness is only 4 - 6 weeks.
Date published: 2016-05-29
Rated 2 out of 5 by from disappointing results Despite fall and spring applications as recommend I had significant new grassy weeds in my Bermuda grass lawn before the lawn began to vigorously grow. Also, I could only find 5,000 sq. ft. bags for my 50,000 sq. ft. of lawn requiring excessive cost investment for mediocre results.
Date published: 2016-05-27
Rated 2 out of 5 by from Average product I used Halt last season and still had a considerable problem with Crabgrass. Product was easy to use, but results were less than effective.

Rated 1 out of 5 by from Wasted time and money I have purchased this product for the last two years and followed the instructions….. we have more crab grass than ever before!
Date published: 2024-07-10
Rated 1 out of 5 by from Very dissapointed Bought and applied in Mid-April 2024 in Minnesota. Looked up application charts, and followed the weather to see when was the ideal time, and applied according to directions. Crabgrass is the worse I have seen and taking over lawn. Thought by buying brand name product and spending more I would get better results.
Date published: 2024-05-23
Rated 1 out of 5 by from No results Had no affect on my weeds at all. I usually use a cheaper brand, but thought I'd see if this was better. After a couple of weeks, I used what I normally do, and my weeds are wilting after just 1 day.
Date published: 2024-04-01
Rated 1 out of 5 by from Made my weeds worse! I put down 2 bags on 8,000 sq ft of Bermuda and St. Augustine in September, and have more POA, chickweed, and crabgrass now (March) than I’ve ever had before. It’s almost like it contained seeds for the weeds.
