Worked well!

this product works very well. I have noticed a significant reduction in weeds using it

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.

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.

Works great. I have used it twice and have had good results both times.

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

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.
