5 Ways to Permanently Rid Your Lawn of Bermuda Grass Weed
Bermuda grass is a tough grass to kill in your garden due to its vigorous growth rate and high-stress tolerance level. Nevertheless, with perseverance and the right tools, you can remove the troublesome weed from your yard once and for all.
First, what is solarization?
This is the use of heat from the sun as Bermuda grass killer. Now, this may sound odd since we’ve already established Bermuda grass is heat resistant.
Bermuda grass is only resistant to moderate heat. When the heat is ramped up, they die. In the solarization method, a plastic tarp is placed over the Bermuda grass weed with the edges held down with stones.
The heat from the sun will pass through the tarp and burn everything on the ground, including the stolon under the soil. The plastic tarp works by magnifying the solar heat rays on the soil under the tarp.
This method is highly effective and only requires minimal labor.
Note: the solarization method will kill everything under the tarp, including cultivated plants. Also, this method is only effective during the hot summer months.
Mulching is the covering of the ground surface to reduce the loss of essential nutrients through evaporation. Mulching can also help in eradicating weeds like Bermuda grass.
You can make use of a plastic ground cover or cardboard to cover the ground. You need to form holes in the groundcover where your cultivated plants can poke out from leaving the Bermuda grass weed under the cover.
Pour wood chippings on the fabric to hold it down and provide nutrients.
Bermuda grass loves sunlight; that is why the summer months are its most active growth season. When this light is taken away from it by mulching, it begins to dry out. It also experiences a choking effect, and after some weeks, it’ll be dead.
3. Vinegar as Bermuda grass killer
Vinegar is an effective method of permanently removing Bermuda grass weed from your garden. Spray a 10% vinegar solution directly on the weed to kill it.
The downside of using vinegar is that you have no control over what it kills. It’ll kill every plant it touches. Use vinegar only when there are no cultivated plants around.
4. Manually Removing Bermuda Grass Weed
When Bermuda grass weed only affects a small area, you can manually remove the weed with a shovel.
Bermuda grass weeds do not grow deep into the soil; they instead spread vertically under the earth. This makes it easy to remove them from the ground.
The best time to do this is when the plant is still tender right after rainfall or after irrigation when the soil is still soft.
Force your shovel some inches under the ground and remove the grass alongside its root. Bag the grass and dispose of them.
5. Systemic Herbicides
Systemic herbicides like round-up are absorbed through the foliage and go through all the parts of the weed killing everything, including its root. This is especially important for weeds like Bermuda grass that can regrow when a small portion of its stolon is left in the ground.
The active ingredient in systemic herbicides is glyphosate.
Ways to Prevent a Recurrence of Bermuda Weed in Your Lawn
