Try corn gluten meal on weedy garden paths.Corn gluten meal, a yellow powder or pellet, is used in livestock feed but it also is an organic “pre-emergent” weed control. You’ll find it in garden supply or agricultural supply stores. Spread it on garden paths (find inspiration for garden paths from this slide show on 16 beautiful garden paths) or beds where you do not want seeds to take root. Read label directions for correct application. Corn gluten meal stops seeds from forming roots when they are germinating. It also contains nitrogen that feeds the established plants in your garden. Apply it early in the season: If you wait until weeds have sprouted, it will be ineffective. Avoid using it on beds where you have seeded ornamentals or where you are counting on plants to self-seed from last year.
