Too Expensive!
I've always used Preen in the past. However, it seems the manufacturer has gotten greedy. The price for this product has gone through the roof! There are other products out there that can do the job.

Doesn't work
I have been using Preen for years and have been very satisfied. New extended product sounded great. Bought 3 large containers. Spread in May, it is now June and we are over run with weeds. Used one container, 2 large containers ready for our rubbish pickup.

It Works, Depending On Application
Preen Extended Control works, but maybe not as directed. I used it a year ago according to application and I got weeds, this past year, I used it again, and this time I put a very heavy application down and it worked, virtually no weeds. So my recomendation is good but if they put down a heavy application.

Extremely Disappointed
I have been using the regular Preen for many years and always had good results. When I discovered the Preen Extended Control, I was expecting to have good results and saving myself the time to not have to put the product down two times per growing season. I put the Preen Extended Control down in March and followed application instructions as per usual. We live in MD, zone 7a. We have over 2 acres of property and several large flower gardens. My flower gardens have always been beautiful in the past, but this year the weeds are overwhelming! Attached is a photo of just one small area.

Dissatisfied User
I did the same to my garden this year as I’ve done years before starting with the weeding. For the most part my gardens were pretty good controlled from weeds. This year is an exception. I weeded as usual, Then as a preventer, I put on your product. Unfortunately it made my gardens worse. I have never had this many weeds before using this product. And that is just my opinion. I will never use it again.

Got rid of the weeds
[This review was collected as part of a promotion.] I used this in my front yard in a couple of areas where weeds had started to take over the grass. There has been hardly any new weed growth since then and my lawn looks amazing. Great product with great results. I'm very pleased. What more can I say?

Not satisfied
I cleaned my flower beds as I have done in the past before applying the regular preen. This time I used the extended preen and the weeds are growing like crazy. Never had this problem with the regular preen. So, I wasted my money on the extended preen.

We are very sorry to hear that our new Preen Extended Control Weed Preventer (stronger than Preen Garden Weed Preventer) did not work as you had expected. There could be various reasons why you are seeing weeds after an application of this product, such as weeds that are not listed that Preen controls, or due to invasive roots or runners such as thistle, grass, etc. Another reason could be that weed seeds already had germinated at the time of application and were not visible for you to remove. Also, this product does not kill any existing weeds but rather creates an invisible barrier that prevents the listed weed seeds from germinating. We do stand behind our products so please email us at customerservice@lebsea.com so we may further assist. Thank-you!

Average Weed & Grass Killer
[This review was collected as part of a promotion.] I found it’s no better (or worse) than any other weed & grass killer. I do like the cap and how easily you can sprinkle it wherever you want. Another + is that there’s literally no mess to clean up when you’re done nor any mixing needed prior to use.

We are glad that you like the application cap. Please note that this product when applied as directed helps to prevent (it does not kill existing weeds) its listed weed seeds from germinating up to six months per application. Thank-you!

Easy to use
[This review was collected as part of a promotion.] We have had this weed preventer for a couple months now, and so far so good. Hope it stays true to the 6 month guarantee on the back. The instructions were easy to follow and it is easy to use. I really like the pour spout on the top that provides even distribution of the granular.

Easy to use
[This review was collected as part of a promotion.] I used this product in the flower beds around the front of my house. I applied in early spring although we didnt have much of a spring this year. We struggle with various types of weeds but mainly breakthrough large grasses. The product is easy to use and the canister is very easy to pour out of. We have a lot of other plants in the flower bed so I like that this is safe to use around them. When it was first applied, I could tell the weeds were reduced but after a few months, they were back again. I'm not sure that this is really effective for as long as it says it is or if I didnt apply it exactly right.

Thank you for your review! Our Preen Extended Control Weed Preventer is to be applied to a weed free area around the label listed flowers, plants, trees and shrubs listed on the label. Watered in to activate. There could be various reasons why you are seeing weeds after an application of this product, such as weeds that are not listed that Preen controls, due to invasive roots or runners such as thistle, grass, etc. Another reason could be that weed seeds already had germinated at the time of application and were not visible for you to remove. Also, If heavy rains were received the product may need to be reapplied sooner than the recommended 6 months. We do stand behind our products and you may feel free to contact us at customerservice@lebsea.com

Great product
[This review was collected as part of a promotion.] I received this about a month ago and my husband put it on our front lawn and we tell tell a difference. We have way less weeds and they aren’t growing as fast as they were before we used this product. I would reccomend.

So far so good!
[This review was collected as part of a promotion.] We put the Preen Extended Control Weed Preventer on our bermuda grass after painstakingly removing all the weeds that popped up this spring. So far we've had a few weeds pop up here and there, but only a handful at a time. Seems to have done the trick! My low back thanks you!

Seems to be working
[This review was collected as part of a promotion.] I haven't had it long enough to say whether it truly does work for 6 months, but so far it has been 2 months and there has been no new weed growth. It's made gardening much easier. The shaker top makes it super easy to apply. I think it is a great product and I am loving my weed-free Spring!

works great on my yard
[This review was collected as part of a promotion.] I bought this about a month ago and I am so happy that I did because it actually helped me with my garden and controlling weeds and I have never been so excited that I haven't had to pull weeds and my vegetables and herbs are flourishing because of the product and I haven't had to pull a weed yet!

Super simple to use
[This review was collected as part of a promotion.] Now that the weather is nice we finally were able to pull the weeds up out of our patio. We sprinkled and spread pot the Preen weed control, which was super simple thanks to the easy pour spout. So far so good, we haven't seen any growth in between the patio stones so far.

Keeps weeds down
[This review was collected as part of a promotion.] I used Preen Extended Control Weed Preventer in my flower beds. We've had a week of rain and I noticed there weren't as many new weeds popping up compared to other places it was not used. I received the product in exchange for an unbiased review, but it has only been used for a month, so I can't tell you how long it works. I'm happy so far.

Soooo AMAZING
[This review was collected as part of a promotion.] Works great!! I used this around my flowers, where I was afraid to cut with the weed eater and it worked wonders. Very easy to use too. I am also glad it did not have a harsh smell as a lot of weed killers do, this one was not over powering.
