Preen One Lawncare - 9 lb. Bag - Covers 2,500 sq. ft.

Did a lot of research before buying this product. It rated at the top of multiple reviews. Our lawn sees dry summers and harsh winters in New York. Weeds were taking over but we didn't want to hire lawn service because we diy everything. We followed the directions like the reviews advised for timing, temps, watering, application. It's been a few weeks now and the grass is strong and healthy and really green! Certain weeds have died completely. Was afraid we'd have bald spots because the weeds were so stubborn and prevalent. So far only a couple of little bare spots, which is exciting because It will be ready to fill in with grass seed in the spring. We'll do it again in the Spring when it's optimal for weed n feed anyway, and see how it does on the dandelions. Noticed there's still a lot of clover, but of all the weeds in our yard clover isn't that annoying and expect that the next application will take care of that.

Couldn’t have flower beds without preen

loved the results of stopping the dandelions! However, not so great at stopping other weeds.

Huge disappointment. Not a weed killed. Applied after a rain so the grass was damp and the product stuck to the leaves. It just doesn't work. Garbage.

This product actually killed 90% of the weeds I wanted. It turns the weeds brown. So you will have patches. But at least you know it is working. I just reseed those areas.

It did not do its job of weeds and didn't really notice a difference in Greener grass

Preen is good. Our grass is much better. It's not instantaneous, but after a few applications, you will see results.

My yard was full of weeds and it was looking pitiful but after a few weeks my grass is green and plush with no weeds.
