Crabgrass be gone!
Little did I know most mainstream weed preventatives don't take care of the pesky crabgrass. After using another brand of Weed and Feed last year my yard was overgrown with weeds and crabgrass last year worse than ever! I got help through Scott's Help Center via phone and emailed them photos of the unidentified weeds in my yard. Due to the "off brand" Weed and Feed I used last year they made some recommendations for Scott's Bonus S Weed & Feed and some Halts Crabgrass Preventer and I'm seeing a huge difference this year! My grass is much thicker and the weeds are almost gone! Looking forward to Spring!!

Great Product
This is a great product to control both kinds of obnoxious crabgrass. Just make sure you apply in the seasonal time period as the product specifies for your region. This product is for serious control of crabgrass and with consistent usage you should no longer have problems. Another note, I used Round-Up Concentrate the first year ...then followed with Halts. I have not had to use Round-Up in the last 2 years, I apply Halts yearly.

Poa annua
Last year my yard had a ton of that nasty poa annua grass
I tried Scotts Halts and this year- - - NO POA ANNUA
Did put it down in Oct and again in April. Well worth the cost
I hated those light green patches that poa annua causes in my
nice yard

This product really works!
We used this product among other Scotts products . We had so much crab grass last summer that we thought we would try this. This year we have had a very small amount of crab grass compared to last year. I would recommend this product very highly!!

Scotts Halts works!
The Poa annua was out of control in my yard and got worse each year. I'd spend hours and hours trying to pull it out; regular weed killer has no affect on it. My sister told me about Halts and said to apply it in March, June, Sept. and December. The first year I did it, I noticed a tremendous improvement the following year. That was 3 years ago. I do it every year during those times now, have a great looking yard, and have passed the word around to my neighbors!

Works well
I've used Halts for years. It's been quite effective stopping the spread of the listed grass weeds. I definitely recommend it.

Yes it does matter what you use for crabgrass and nothing works as well as Scott Halts.

Great for early spring crabgrass control and fertilizing
Crabgrass was always a problem. With Halts, I no longer have a crabgrass issue.

Good Product
We've had issues with crabgrass in the past, so this was a good product to try out. Was easy to spread, no issues at all with application. Used in addition to our already purchased seed & fertilizer. Everything looks good so far, and we're looking forward to a healthy lawn moving into summertime.

Working well so far.
I spread the this on my lawn in the late evening to give it a chance to work its way in with the morning dew a few weeks ago. It appears that it is working well as the amount of crabgrass and weeds are less than what I first experienced this season.

Stop in the name of crabgrass
Applying the product with a spreader is easy. It has been a few weeks since I applied the product and I have seen less crabgrass but the dandelions are still there. I would use a different preventer that calls out dandelion for use, if that is the main weed/unwanted plant that you want to suppress for the season.

Effective
Living in the south, with clay soil I tend to grow everything but grass. Literally. I know I can always count on Scotts products to help.
This turf builder halts crabgrass is easy to spread and you get a good amount. Works very quickly at controlling crabgrass and helped to start some healthy regrowth.

East to spread and goes a long ways!
This is the first time I have used the Scott’s Crabgrass and grassy weed preventer. I live in Northern Indiana and applied this product mainly for crabgrass prevention. It seems to be doing the trick.

Giving it a try
We applied this crabgrass preventer 4 weeks ago to try and help with the crabgrass in our yard and my neighbors yard but we haven’t seen much changed. I’m hoping with continued applications and consistency it will make a difference. Easy to apply and minimal smell

Scotts Halts Crabgrass @ Grassy Weed Preventer
The Scotts Halts Crabgrass @ Grassy Weed Preventer so far has done ok with the current weeds present. I still see some in the yard in spots so hopefully once I spray them with some weed killer they will not longer be there!

Easy to apply
Just had the product shipped to me and applied it today. Instructions were clear and easy to follow. I hope that it is not too late for the spring application to work. I will follow through and apply on fall as well.

Helps with weeds but still see some crabgrass
Helps with weeds but I still see some crabgrass. I didn’t think this was shipped early enough since this is more of a preventative (pre-emergent), so we will have to see how it looks once it has a little more time to work.

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.
