ScottsWeedEx Prevent with Halts, Crabgrass Preventer, Pre-Emergent Grassy Weed Killer, 5,000 sq. ft., 10.06 lbs.

This product works great if your lawn gets crabgrass. I usually treat my lawn with this product to prevent crabgrass and later use a weed and feed for the dandelions, etc. I find this combination works the best for my lawn as I have irrigation water and this is the best combination I have found for my lawn.

haven't had 100 percent success but definitely has helped with annual weeds. Repeat buyer.

I was actually surprised at how well it worked. My lawn is always rampant with weeds, but not now. It was put out early in March, about 4 weeks ago and all good so far.

Been trying to get rid of crabgrass for years. Decided to try this approach. just put down last week so too early to tell. I liked the season long longevity of this product.

Does not kill weeds, just prevent new ones. It says it on the back of the package in small print. I don’t recall reading it on here. I need something serious to kill my crab grass.

Works well on my yard. Crabgrass is a difficult weed to combat.

I was particularly concerned about coverage, because these bags are small and the product is not cheap. I've got an old Scotts Accugreen 1000 drop spreader that hasn't always given me consistent performance, but this time I got 5,000 sq ft per bag, as advertised. I first checked the calibration of the spreader's shutoff bar, as described on the Scotts web site. After doing that, I noticed something that I never had before. The "micrometer" on the handle that is used to dial in the numeric setting for each product does not reliably hold that setting on my old machine. Every time that I open and close the shutoff bar using the control lever, as in each time that I reverse direction, the "micrometer" inches a bit looser. A short piece of adhesive tape fixed that. I just happened to apply this pre-emergent weed control under nearly ideal spring conditions, so I won't know its effectiveness for months, but I am hopeful.Update: In 2022 I got good -- not excellent -- results using Scotts WeedEx Prevent with Halts. In 2023, I found what looks like a comparable product, Spectracide Weed Stop plus Crabgrass Preventer for 1/3 less than the price of the Scotts product. Spectracide is not an off-brand. Again, I was able to apply it under nearly ideal spring conditions. By summer, it was clear that Spectracide performed every bit as well as Scotts, which is to say about 85% effective. I spray broadleaf weeds that pop up during the season with Ortho Weed B Gon. I've still got a few woody-stemmed weeds like black medic that seem to resist all chemicals that I put down. I pull these up by hand, which is in itself a gratifying exercise, and I believe that after a few years of this mixed strategy I have mostly gotten ahead of them.

Good stuff works in the spring in Florida
