Kills tough weeds and grasses to the root, including dandelion, crabgrass, poison ivy, clover (red and white), spotted spurge and other broadleaf weeds. It is rainproof in as fast as 30 minutes, produces visible results in hours, and allows you to plant 1 to 30 days after application. Use in and around flower beds and perennial landscape plants, around trees and shrubs, on patios, walkways, and driveways, gravel, or mulch beds, along fences and foundations, and edging around foundations and retaining walls.
