Bermuda grass reproduces by rhizomes (beneath ground shoots), stolons (vine-like shoots), and by seed (above ground). Seeds of Bermuda grass remain viable in the ground for a couple of years, and this makes it very difficult to get rid of even with several applications of potent herbicides.

Bermuda grass is often used to control erosion, grown in high traffic areas, and athletic fields. That is because of its vigor and great tolerance of heat, drought, and heavy foot traffic.

Bermuda grass can be gotten rid of chemically or mechanically. The chemical method is highly preferred when they are either growing on their own, alone or in lawns—that way, no flower or edible vegetable is poisoned or damaged by toxic herbicides.

Another means of getting rid of Bermuda grass when it is not in flower beds is by solarization with black plastic or constant rototilling.

Solarization involves using the sun to get rid of Bermuda grass to its roots. This process is time-intensive and usually takes up to 30 to 45 days to yield positive results.

Solarization or use of solar power is done by covering the Bermuda grass with clear plastic mulching or with black polyethylene for two months during either mid to late summers in warmer climates or during the warmest part of summer respectively.

Now, if Bermuda grass has grown or is growing in your flower beds and you wish to keep it out of the flower beds, you need to get rid of it mechanically. This mechanical process involves hand pulling of the grass from its roots.

If the seeds have set in already, you might experience a re-growth of the Bermuda grass two years after you manually pulled the grass out by its runners.

Step 3

Dig up any underground rhizome. Do not leave any rhizome behind, no matter the size. Even the tiniest rhizome is capable of growing into Bermuda grass if you leave it behind in the soil.

Step 4

Apply grass specific herbicides. Grass specific herbicides such as Over the top, Vantage, Ornamec, and Grass B-gone are applied only when the grass runners are so deep into the soil and cannot be pulled out. These herbicides kill the grass and should be repeated if any new shoot crops up.

Step 5

Isolate your lawn from your flower beds and garden. A good barrier should be first put up between the flower beds and the lawn.

A barrier could be made of a polyethylene bag or a plastic edging. Use the black polythene bag as a barrier over the Bermuda grass and then use plastic edging around the flower bed.

The plastic hedging should be installed at least 6 inches into the soil to prevent the Bermuda grass from spreading into the flower bed and competing with the flowers and other useful plants therein.

Leave the polythene bag over the grass for a period of six to eight weeks during the regular growth season of Bermuda grass, which is usually during warm periods of summer. Ensure to trim back your lawn at the edge so that stolons don’t encroach over it.

Additionally, to keep Bermuda grass at bay from your flower bed, you should much your plant and flower bed. Mulching helps reduce the rate of Bermuda grass invasion.

You can also spot treat the Bermuda grass. You do this by using non-selective herbicides such as Glyphosate.

Glyphosate is an active ingredient in non-selective herbicides that kill all forms of vegetation it comes in contact with, so you might want to cover your other plants and flowers with cardboard to protect them from the herbicide.
