A product lives up to its name

Before I bought and used this weed preventer, I had my suspicion whether this product would actually live up to its name and intention. After I used it, I saw a significant reduction in new weed growth which saved me considerable time to manually remove new weeds. I planted Dymondia, a ground cover with slow growth, on my front lawn. To prevent weeds from taking over the lawn, I spend numerous hours to remove them. Now my front yard looks very pretty and lives up to its name of 'silver carpet'. This product came with a handy scoop-spreader and is easy to use and help spreading the granules evenly with little effort. This purchase is my second bucket of preventer.

I always use Preen. People don't understand that you have to get ALL weeds out 1st before applying. I weed in spring, apply %26 I have little to no weeding to do the rest of the summer. Weeds will not germinate.

This does not kill Florida weeds

It didn't even kill one Florida weed I use the entire container exactly as said in I got a tiny bit left and it's junk. I will never buy that again. Complete waste of money.
