Crabgrass, a thing of the past
Just laid this down, will expect results soon. Like all Scotts products I've tried I'm sure it will do just fine. Crabgrass preventer and feed has always worked for me, takes time but has always done the job.

Good but not organic
Really great for the yard we replanted. Do wish this was more organic for kids and pets but overall happy with how my lawn looks so far this spring!
Will reapply in the fall for max benefit! Can’t wait

Unwanted Grasses
If you have Kentucky Bluegrass this product is not the best for that species. Otherwise it certainly works well on unwanted grasses.

Effective results
As a preventative product, I have been very pleased with its performance. However, this year, I plan to reapply again once the growing season (St Augustine grass) gets going. I noticed las year that towards the end of the summer crabgrass started to appear.

Liquid Crabgrass control
I have been using Scots Crabgrass control for years, this is the first time I changed and used the liquid style. Much easier and Quicker. Results were great my late summer early fall lawn is clear of any crabgrass( except for 2 spots I missed Oops) Definitely will use from now on

Decent spread for specific weeds
I still had a lot of weeds after using this but it is geared mainly toward a few specific weeds and I don't see any of those in my yard so it appears to have done it's job as far as I can tell. I think, overall though, I'd prefer something like Weed & Feed unless I was having an issue with just one of these weeds.

Does kill
I will say I did see some quick results, but then we had a flooding type rain storm that killed a lot if grass. So unfortunately I cannot vouch for long term.

This product worked quite well!
This product was very easy to apply with the spreader. There was no dust flying when applying either. I gave it plenty of time to work and it has. Unfortunately the cold weather set in and now I cannot see how well it completely worked.

Crabgrass preventer
It appears very easy to use, and I’ve always had great experience with scots products. Instructions are to use in early spring, so I haven’t been able to apply it to my lawn

Great Product for Beginning the Season
We created a lawn care plan on Scotts and it recommended this product for our first treatment (centipede sod planted in 2009). Started working within a week. Great product and does what it says. Helped get our yard off to a good start. Highly recommended. We also recommend getting a lawn care plan.

Over promoted for performance-when it comes to Crabgrass
Crabgrass is the first WORD on the product. However; it comes in last on performance. I have used all the products that concern crab grass.
At best a minimal effect on crabgrass but does seem to kill and prevent henbit and other cold weather emergent weeks. To give this product a better review it would need to act faster. I have to admit CRABGRASS is near impossible to deal with. So I also, spot kill individual mature CG with Pure Vinegar.
I still recommend it. I use a scotts drop spreader which gives me the precise amount to use. Cut your yard as short as possible if heavily infested, then spread it early morning when DEW has formed or the night before. This seems to activate on the small leaf stems and absorbe the Halts. AAA+++ no ODOR. Be safe with Kids walking recently treated areas without shoes.

Best to use twice
We have a friend who work for a University lawn research facility and he told me use this product once early in the year (FEB) and then again in 6-8 weeks. He said don't use the weed & feed as your second treatment, but use it 6-8 weeks after the second treatment of Halts. Now this recommendation may only be applicable in the Virginia area as that is where he does research. So far it is working - not one sign of crabgrass yet this year. I have used this product for many years and like it very much. Now that we know the trade secret, it may be even more effective and I will like it even more! Highly recommended.

Please don't stop manufacturing this product!
I've been using Scott's Halts for 12 years on my N. Florida lawn, where we have a year-round growing season. It is a constant battle to fight off the weeds from my neighbors weed-choked yards. This product is excellent on crab grass as I only occasionally find any in the yard, which is over an acre. It helps somewhat with winter weeds, which are a huge problem; henbit, in particular. I also spray broadleaf winter weeds, especially oxalis, so this granular product is not the only product in my arsenal, but it is essential. My lawn is a mix of Emerald Zoysia and centipede. The Zoysia can typically withstand liquid broadleaf herbicide, but centipede can't take the strength needed to have any effect on the weeds. I do not want, and will not buy, a weed & feed as I use organic matter to fertilize my lawn. Additionally, you should not be fertilizing and putting down herbicide at the same time. This is a marketing tool for people trying to save time, but the optimal application timing for each are not the same. Both Home Depot and Lowes have stopped carrying this product over the years, and I am lucky to still be able to buy online. I have a feeling, though, that Scotts will stop selling Halts at some point, and will only offer it through its weed & feed products. I don't know what I will do at that time, but it is going to be a big problem.

It Helped
While I still had crabgrass, it was much less and in one or two more years I should be rid of it. I have four acres and cannot use Halts on all four acres but it definitely helped the part I consider the lawn.

Hit or miss
The products works- sometimes. While there is a several month window over which the product can be used, it seems to me that it works best when used earlier as opposed to later in the application cycle. The product is also expensive. When used as part of four step annual application, it gets really expensive.

My crabgrass stays prevented until mid summer in the St Louis area, then it needs a reapplication.

Great preventative product if used properly
I purchased this product early in the year and applied it to my yard just as the grass began to green-up. I noticed I had crab grass in my yard in select areas. After applying the product it not only killed what was there, it also kept it from coming back all year with just 1 application!

Does the job
My neighbor's lawn is overrun with crabgrass. I have been diligent about keeping halts on my lawn (bermuda) per recommended schedule and don't have a problem at all.

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

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.
