I don't know if it works or not, I spread it around as the directions say and no weeds have grown, so either it works, or the weed fairy is picking weeds at night while I sleep.

This stuff works great. The one thing I did not like about it was that it was impossible to spread it evenly from the dispenser. I had an empty Preen jug that I poured it into. Problem solved!

Seems to work better and longer than Preen. My weeding chores have been GREATLY reduced. I’ve been plagued with an infestation of yellow nutsedge in multiple flower beds for years. And while some still pop up now and then, it amazes me at how few there have been this year since I started using this. I never want to be without it.

I am a retired landscape contractor and have been using Preen for my home landscape beds for over 30 years. Because Round up weed killers Liquid and granular have worked so well for my commercial and personal applications that I assumed the new Weed preventer would also be a good product. WHAT A MISTAKE!!! It is nearly impossible to use more than 1 or 2 ounces as directed. Additionally, the printing on the package, the instructions and acceptable plants are so small that a magnifying glass is necessary to read them.

This is working in my flowerbeds and rocks- well worth it to me. Sprinkled and then covered with fresh mulch around rose bushes—- put everywhere in back in the xeriscape areas. Saves time pulling weeds on the w/end!ðŸ‘Texas
