I use in my flower beds this past summer and it worked great. I started getting my flower beds ready this spring and not many weeds to talk about. It does a great job. Very impressed.

I put down an extra heavy application and it still only worked at about an 50% level. Still looking for a great weed killer that you can put next to plants.

Preen is amazing! I have a hillside that was basically weeds when I first started using Preen. Now it gets an occasional weed. I put it around plants in flower beds and weeds stay at a minimum. You do have to use it twice a year to be effective.

5 stars ! Works like a charm on burweed!
I had a large infestation of burweed, very thick. I cleaned up as much as I could, but the burrs were all over, deep in the rocks so I couldn't get them out. I applied this as directed in October. Over the past few months we have received plenty of rain (So Cal) but I don't have any weeds in the areas where I applied this! I am super happy, will use again as needed.

    Easy to spread with my hand spreader. I wish the store had a larger bag available. I'll truly find out in 3-6 months when I'm looking for weeds to pull.

    Preen Extended Control is not a weed killer. It helps prevent new weeds from sprouting. You do need to reapply it every 6 months.

    As long as I get it spread before a rain, it keeps my weeds to a minimum.
