Got this for my new flower bed and I still have grass and weeds growing in there and they are not growing from the bottom they are growing from top and I put this product down soon as I planted the plants to prevent and it did nothing to stop it from growing. Very upset! This is not worth the money at all.

I started using this product a few years ago and I still use it, if you want to have a seedless garden I highly recommend this product, it does what it says, I apply this product early in the spring, just before planting my garden, and I have a weed free garden. Trust me it works

What changed?

Would Not Recommend

It used to be weed and feed together, and it worked great. But now that it is just weed preventer it doesn't seem as effective. We put this down before we mulched--like we always have, however I spent last night pulling weeds from my garden. Not impressed!!!

Prevent weeds instead of pulling them

Would Recommend

I bought this recently and used it in my flower beds. It is too early to say how well it works but I am looking forward to not pulling any more weeds.

Non toxic and effective

Would Recommend

I was skeptical at first, but this product was easy to use and prevented weeds from germinating. Probably need to apply several different times throughout the year.
