Vegetable Gardens

Preen Vegetable Garden Organic Weed Preventer offers completely organic weed prevention and is safe for use around children and pets. Made with 100 percent corn gluten, this natural pre-emergent herbicide not only keeps weeds out of the vegetable garden, it also is effective in beds of annuals and perennials and around trees and shrubs.

Snap beans, corn, tomatoes and other desirable plants are deprived of water and nutrients when weeds, such as lambs quarters and clover, are present. When applied monthly, Preen Vegetable Garden Weed Preventer keeps broadleaf and grassy weeds from growing naturally. That reduces weeding duties and saves you time and work.

Preen Vegetable Garden Organic Weed Preventer is safe for use around established vegetables, herbs, fruits, annuals, perennials and other plants.
