Good product
This is a better product than the regular Preen. It helps me a lot to manage the weeds in my rock gardens although it says six months it has to be applied at least twice per weed season and I live in the northeast so we only weed growth 4 to 5 months a year. I do recommend this product.

So far so good!
Would RecommendI purchased this to lay prior to pouring gravel onto our landscaping. I used this plus fabric and no weeds after 4 months so far. I like to lay this down around bushes and shrubs since it’s safe!
