How to Control Bermudagrass

Overview

Bermudagrass (Cynodon dactylon) is a common warm weather perennial turf grass grown throughout the southern United States. It is also often used as a livestock forage crop. The grass was brought into America from Africa in 1751. The grass, which spreads by underground rhizomes, readily grows along roadsides, in orchards and forest settings. It is often considered to be a very invasive weed by homeowners and landowners.

Step 1

Abstain from watering any area that contains Bermudagrass. Bermudagrass needs water to grow during the hot summer season. If the grass is not watered it will quickly begin to dry out. Till the soil up two or three times during the summer. Pull all the stolons and rhizomes off of the grass and dispose of them.

Step 2

Lay down black recycled plastic mulch in flowerbeds or areas that are plagued by Bermudagrass growth. Cover the grass area with 3 to 4 inches of mulch to withhold light from the Bermudagrass.

Step 3

Plant trees and shrubs in areas that are plagued by Bermudagrass. The grass requires abundant sunlight to thrive. When Bermudagrass is shaded the grass's growth becomes weak and sparse. Remove weak growth using a hoe, rake and garden trowel. Dispose of the Bermudagrass to prevent regrowth.

Step 4

Apply a post-emergent herbicide in spring and summer. Follow the directions on the label for application. Remember that herbicides can damage other plants and grasses, too. A grass-selective herbicide will kill most plants that belong to the grass family. Non-selective herbicides will kill almost all plant life including the Bermudagrass. Different varieties of post-emergent herbicides and non-selective herbicides are available from garden supply centers.
