Apply in the fall (August-October) to prevent moss (except in California), or to prevent the germination of Poa annua, henbit, corn speedwell, and chickweed.

  • Works great in my yard!
Makes my grass so green!

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

  • accurate @ 5,000 sq ft
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. ... show more

  • Great Product
Third time ordering! I tried this product last year and it really made a difference in my front yard. I have already applied it this year to the front yard. Now I will apply to the back yard. I would recommend this product if you don’t crab grass.

Followed the directions as best as possible, and I still have tons of crabgrass growing.
