What Customers Are Saying
The Scotts WeedEx Prevent with Halts product appears to be an effective pre-emergent for controlling crabgrass and other weeds in lawns. Many customers reported it successfully prevented weed growth, leading to a healthier, greener lawn. The product was easy to apply, and worked well when applied in early spring and fall. However, some customers had mixed results, with certain weeds like annual bluegrass still growing. Adjusting the spreader settings higher than recommended was also needed by some to achieve adequate coverage. Overall, the majority of customers were satisfied with the product's performance as a preventative measure when used as directed.

Would Not RecommendGiven its on the title, I thought Scotts would work. I was completely wrong. My crabgrass is back better than ever. Didnt even slow it down.
Carefully check products delivered to car!
Would Not RecommendThe Lowes employee carefully carried a small bag of crabgrass killer and slowly placed it in the trunk of my car. I wondered why he was being so careful- it looked fine. After arriving home, I removed the bag from the care and noted with disgust that back of the bag was badly cut and poorly repaired with wide shipping tape; the crabgrass killer spilled out on my driveway and shoes. It will be exceedingly difficult to empty the bag without a major spill.

Hmmm...
Would Not RecommendIt works but not all the time! Maybe my grass is becoming immune to it - I've been using this product for the past 8 years. I placed it on my grass 2 weeks ago, and as of today I still have weeds. I might have to spray a competitor's product on my grass instead... also, I followed the instructions on the bag, using a broadcast spreader, and I ran out of product; my property is slightly less than 5000 sq ft. If I decide to use this again next year, I'll have to get 2 bags.

You sent the wrong item this is such nonsense.
Would Not RecommendYou sent the wrong item now I have to go to the store to return it. This is such nonsense. The whole reason I ordered it online is so I wouldn’t have to go to the store because there’s not any store near me —so unfair —your pickers need to know the difference between Halts and weed X.

Works
Would RecommendI don't like when they package fertilizer with crab grass preventer since its too early to feed my grass. This product is just crabgrass control and it works well.
