Preen Lawn Crabgrass Control 15 lb. Bag, Covers 5,000 sq. ft.

I put it in my lawn spreader and the rest was easy. I have noticed less crabgrass but still more to go as I had a lot.

I hit the lawn mixed with crabgrass, newly sprouting spurge, and chickweed with some ortho weed killer first to kill existing weeds. Speedzone southern lawn works better but all I had was some ortho. Turned most weeds yellow but did not kill all...about 50%. Put the Preen over a few weeks later and killed the rest and preventing spurge seeds from invading. Happy with product.

Good product. Has not eliminated 100% of crab grass. However, it probably reduced it by 85%

Worked well!

Preen is absolutely amazing. You must follow application instructions and it's important to apply when it tells you to (i.e. before crabgrass emerges, not after it emerges). I live in New Jersey. Every Spring, my lawn is practically free of clover and crabgrass after the first application. I have used Preen for about 4 years now and will never go back to that worthless SCOTTs product which only nourishes the weeds and crabgrass. After I use Preen Crabgrass Control in early spring, I maintain lawn with another feeding of Preen All in One around late August. June and July the grass is drying up with the harsh heat and sun, so i don't waste Preen when the grass is going dormant. With Preen, you don't need the 4 different applications that SCOTTs makes you do. So worth it. Definitely recommend Preen products.

Used as recommended but it only made the crab grass grow faster.

I will retract my original, "very disappointing" review. I have seen darkening of crabgrass in my lawn. Although it's been at least 4 weeks, and I think I will need another application. I still expected it to be better based on reviews.

For years I used the "other" brand of weed prevention granules. They worked ok. Unfortunately, i had a crab grass invasion like I've never seen before. This stuff took care of my actively growing crab grass. I tried the spray to kill the individual pieces that were popping up to no avail (plus it turns them white, and they stick out like a sore thumb). I put this down and the crab grass that was growing died and not a single new one sprouted. I'm not sure what magic they used to create this, but it works.
