Killing Bermuda in Fescue: Guide
If your yard has a small infestation of Bermuda grass, you can dig this out rather than use a chemical herbicide. Weed kills should only be applied to your lawn as a last resort. Herbicides can be a health hazard to humans, pets, and wildlife, so they are best avoided if possible.
If Bermuda grass is taking over your lawn, use herbicides as spot treatments. It’s best to attempt to kill Bermuda grass, either by digging it up or using herbicides during the growing season. Herbicides can be applied in early spring. The best time of year to plant fescue is in early fall.
You can try to kill Bermuda grass in Fescue in the winter, but it’s not recommended. When Bermuda grass is dormant, it won’t absorb much herbicide and will be harder to get rid of.
Using a Weed Killer to Kill Bermuda Grass
There are many herbicides available that can effectively kill Bermuda grass and control the weeds in your lawn. However, it would help if you were careful when using herbicides as they can also kill your Fescue grass and other plants.
If you decide to use a herbicide, you’ll need to choose one that’s safe for your lawn. There are two different types of herbicides available: selective or non-selective herbicides.
Non-selective herbicides are sometimes referred to as broad-spectrum products; they are a great way to kill Bermuda grass in a fescue lawn. These generally contain glyphosate, which penetrates the roots of the plant to kill them. The problem with non-selective herbicides is that they will also destroy your fescue grass and other nearby plants.
It’s best to use a selective herbicide to target the grasses or weeds you are trying to kill. If you decide to use a herbicide, you can apply it to the whole area that’s affected by Bermuda grass grows. Once the soil absorbs the herbicide, it will be turned into carbon dioxide, phosphate, and nitrogen which are toxic to Bermuda grass.
