---|---|---|---|
Remove Existing WeedsRemove any existing weeds, taking care to remove their roots. Preen garden products do not kill existing weeds, they prevent them. |
Mulch the AreaA three-inch layer of mulch helps retain soil moisture, keeps soil temperature even and looks nice and tidy. Mulch also has preventative properties of its own, assisting Preen in keeping weeds away. |
Apply PreenSprinkle Preen on top of mulch. Apply when the garden is dry so Preen granules won’t stick to wet plant leaves. |
Water To ActivateAfter applying Preen, water the granules to release ingredient that forms an invisible barrier that blocks weeds beneath the surface. |

Product Description
Product Description
Stop weeds before they start for up to 3 months guaranteed
From the Manufacturer
Preen Garden Weed Preventer stops weeds from germinating in flower and vegetable gardens, in ground covers and around trees and shrubs. Although Preen will not kill existing weeds, it will prevent new weeds from sprouting - eliminating the need for difficult and time-consuming hand-weeding. Without weeds, your valuable plants can grow larger and stronger. Apply Preen Garden Weed Preventer anytime during the growing season around established plants and transplants. Preen should not be used on flower seeds. It can be used after flowering plants have germinated and are 2-3 inches tall. Preen may also be incorporated into the soil when seeding vegetables or applied after mulching beds. By applying Preen as early as possible, you can eliminate the need for hand-weeding. Rain does not wash this product out of the soil. To keep beds weed-free all season long, reapply Preen Garden Weed Preventer every 9 - 12 weeks.

As the manufacturer explains, it won't kill current root structures, which is why it's safe around ornamentals. In my case I first burnt all the (then empty) beds using a propane weed torch. I then applied Preen and over the next few weeks pulled any weeds that did emerge. I expected some to come back because the weed torch, as with Preen, does not kill the plants roots but only destroys the above ground greenery. I chose this approach because I wanted to get shrubs and other plants into the beds this year, and any type of standard herbicide like Roundup could have hurt these plants also, not to mention the other highly negative effects of Roundup on wildlife, ground water, and the environment. I've been pleasantly surprised by how few weeds have come back, and even more to see that once I removed these weeds the Preen application has done its job--I have seen no perceivable weed growth in the areas I cleared with this method. The application process is easy, and an every 2-3 month ritual is still much easier than pulling weeds or reapplying mulch. If it keeps working like this, Preen will have a happy customer for life with me!
The picture I've included is a formerly weed infested bed about a month after pulling weeds and then applying Preen--weed growth is near zero, and we've have plenty of soaking rains to encourage them.
