Pre-emergence Herbicides

Weeds can be a gardener's worst nightmare. To help keep them in check, you can use pre-emergence herbicide products.

Pre-emergence herbicides are applied before weeds are a problem and keep weed seeds from growing and emerging from the soil.
They're commonly used in the lawn, but can also be applied to landscape beds. A two- to three-inch layer of mulch will also help keep weed problems down in your beds.

Pre-emergence herbicides can be applied in either liquid or granular form, and are often specific to particular kinds of weeds. Always read and follow directions for how and where to apply any pesticide.
