Preen
Stop weeds* before they start for up to six months, guaranteed. Preen Extended Control Weed Preventer can be used around 600 plants in perennial flower beds; around groundcovers, trees and shrubs; and in arid landscapes and rock gardens.
Preen Extended Control Weed Preventer can be applied up to two times per year around established plants and transplants. A first application can be made any time throughout the growing season — spring, summer, or fall. For ongoing weed protection, a second seasonal application can be made two to six months after the first application.
When planting or transplanting into an area treated within the past 12 months, use fresh soil to fill in planting holes around plant roots, or injury may occur. Disturbing the soil surface after activation may result in erratic weed control.
