Fertilome Weed Free Zone is used to treat weeds that are actively emerging in a lawn and will not prevent new weeds from emerging. Monterey Vegetable and Ornamental Weeder is a pre-emergent herbicide that helps to control grasses and broadleaf weeds. This is one of the only products that is safe to use in vegetable gardens, and can also be used in flowers, trees, shrubs, groundcovers, and rock gardens. Vegetable and Ornamental Weeder will provide weed control for five months; simply apply to soil surface and water in.
