What Customers Are Saying
The product provides mixed results in controlling various weed types. Some customers report excellent weed prevention, particularly against dandelions and crabgrass, while others find it ineffective, especially on Creeping Charlie and Bahia grass. Many praise the ease of use and long-lasting weed control, but a significant number are disappointed, noting the need for multiple applications to see results. The effectiveness appears to depend on the specific weeds present and proper application according to the instructions.

Would Not RecommendI applied 50-pounds of Preen Lawn Weed Control, following the instructions on the bag. After more than 3 weeks, there still aren't any weeds dead. None are even wilted.

Waste of Money
Would Not RecommendI bought this product because preen has a good reputation and the lawn care person at Lowes suggested it. I have never used preen products before. I followed the instructions exactly as written on the bag. It did not kill the weeds, in fact it's more like it made more grow

Very hard to find in stores
Would RecommendPreen we control is without doubt the very best weed killer I have ever experienced in my yard. I just wish it was available in stores.

Sorry
Would Not RecommendI purchase this product and put it down according to the instructions and five weeks later, the weeds keep coming. Not a very effective weed preventer.

Wasted our Money
Would Not RecommendWe applied Preen at the beginning of summer, and it did not kill any weeds. We followed all instructions, but we noticed no difference in our lawn at all. It is very frustrating because we spent $57 on bags of Preen and then found out that the local weed killing company who comes out to the house to spray only charges $40. We will not be using this product again.

Waste of money
Would Not RecommendBought 3 bags of this product. Taking 2-3/4 bags back to Lowes. Killed everything except the weeds. Now I have a lawn to replace. Contacted customer service, as a courtesy, to advise them that their product killed my entire lawn. Customer Service experience was a joke. Terrible product and terrible organization.

Preen Lawn Weed Control
Would Recommend[This review was collected as part of a promotion.] I've never been unhappy with any Preen product I've used and this one doesn't disappoint either. We live in the country and back up to an empty lot with a lot of weeds. We spread this on that side of the yard to help keep those weeds out.

Green weeds are bad
Would Recommend[This review was collected as part of a promotion.] If it was green - it was okay for me. Not so much anymore! After digging out my dandelions by hand, I switched to Preen. Great product!

Works like a charm!
Would Recommend[This review was collected as part of a promotion.] I have used this product for several years, and it does a great job at controlling most weeds in my yard. I even put some on my neighbors yard to prevent all the dandelions from coming back. Great product, does not destroy your lawn.

Another Preen product to add to my must have list!
Would Recommend[This review was collected as part of a promotion.] I've never been unhappy with any Preen product I've used and this is another product to add to my list of organic products. We live in the country so we never have a neat tidy lawn but this helps keep the yard looking good. I feel good knowing I'm not going to harm any of the wildlife or pets.

Beautiful weed free lawn
Would Recommend[This review was collected as part of a promotion.] Been buying Preen for years, easy to use...Just drop it according to directions and enjoy a weed free lawn for months after, Only issue i had was years ago when i applied it before a full week of heavy daily rain. Of course the heavy rain water diluted the product so i had to reapply after a month...great product

IT WORKS!!!!!!!!
Would Recommend[This review was collected as part of a promotion.] Used it on my front garden which mainly has shrubs. The shrubs are surrounded with river rock. Last year, I almost lost my mind picking weeds from between the rocks, but this year I used Preen and I haven't seen a weed yet!!!
