Features & Benefits
Won’t Harm Desirable Plants

Won’t Harm Desirable Plants

With Roundup Landscape Weed Preventer, you can be confident that you’ll be preventing weeds but not damaging the plants you love. It’s safe to use in annual flower beds, around established trees and shrubs, near perennials, in ground cover, and between ornamental grasses and bulbs.

Convenient

Convenient

Creating a barrier against weeds is easy thanks to the built-in applicator which helps provide even coverage to protect just those areas you want to target. Additionally, the in-bag handle makes holding either size - the 5.4 lbs. bag or the larger 13 lbs. size, a breeze. After applying, you can leave it on the soil surface or rake it into the top inch of soil, then just water to activate. It’s never been easier to outsmart weeds.

Prevention

Prevention

Wouldn’t it be nice, for once, to enjoy a weed-free season? Roundup Landscape Weed Preventer won’t kill existing weeds (try Roundup Weed & Grass Killer III for that), but will prevent weeds from growing for up to 6 months.
