... me so long to find this product it works great.

I don't know why it took me so long to find this product it works great.

Buy it!

Have always used Preen and love it. Don't know if this will last 6 months but will test it this summer.

Five Stars

Great product; kills the unwanted weeds! ...been using this product for a few years now. Very satisfied!

A must for life in the woods

We live in the middle of the woods and our garden weeds are out of control. We find that sprinkling preen over all our garden beds in early spring helps keep the weeds at bay. It's worth another round later in the season too. Good product, good price and convenience from Amazon.

It actually works!

Does exactly what it says it does. Pulled out all weeds including their root systems, sprinkled Preen, then sprinkled water over top. 8 weeks and not a single weed has returned. I put this in an area that gets grass blown into it after cutting our grass and no grass or weeds have grown there yet. Very happy with this!

Five stars for easy of use - great shaker top dispenser

Ordered this when the weather warmed and there was no snow. Got it down despite the cold, hoping to beat off early spring weeds on a large landscaped area of the property. Five stars for easy of use - great shaker top dispenser, it goes down easily. I've used Preen before and gotten great weed control for three months - interested to see if this one really delivers 6 months weed control - will post an update in spring.

Five Stars

It really works!

Useful product

Bought this item for use in a flower bed at my daughter's elementary school. River rock had years of composted material underneath, so after removing the composted material and before replacing the rocks, I put this product down to prevent future growth. I checked on the beds just the other day, 2 months after using this product, and no growth has occurred.

This is probably one of the best purchases I’ve ever made

This is probably one of the best purchases I’ve ever made. Incredible. There’s definitely, MAGIC stuffed inside this yellow tub! Haven’t had to pull a weed in months. I’m a farm owner with lots of property and I used this on the side and front of my house. Haven’t had to even think about the landscape since. Able to move onto other projects and my animals. One HUGE PART OF MY SUMMER, THANK GOODNESS,,,,, I KNOW LONGER HAVE TO THINK ABOUT! What a blessing. Thanks SO MUCH!😌🐑🐴🐾👍🏼

Works, Follow the directions

I had issues with my flower beds and broad leaf weeds. I had been using various post emergent products to kill the weeds but in Florida it can be quite the task given stuff here grows so rapidly. I was out there killing weeds every 3 days. I bought some Preen, spread it out liberally and watered it well with the hose. I had a couple of sprouts come up right after as they were already sprouted so the preen wasn't going to do anything for a weeds already in the process of growing. After those few, I have had 0, zilch, nada weeds. Nothing. This product works, it is freaking amazing. I will be using it when needed. Absolutely in love with not having to mess with weeds anymore.
