Getting rid of Bermuda grass can be a big challenge, especially if you live in an area that is warm, or at least rarely gets below freezing. This warm-season grass is often a choice of turfgrass for some homeowners, but not everyone likes it. If your neighbor is one who does, then you may quickly find it searching for a home in your lawn as well, as the grass can spread up to six feet a year. Further, it is a very competitive grass in the summer and may be able to overpower many other types of grasses, making it even more formidable.
Determine the extent of the Bermuda grass growth and till that area with a rototiller or hand tiller. The hand tiller is by far the harder method, but it can be used by those who do not have a rototiller.
Allow the treated area sit for a two to three weeks. During this time, do no other treatment on the area at all.
Return to the area and till it again after this period of time using the same method and vigor you did the first time. This should be done as soon as you begin to notice new growth in the grass.
Repeat this process one or two more times. It may take a while to put the grass under enough stress that it dies, but it eventually this should kill Bermuda grass.
Choose a herbicide that has glyphosate in it. This is often a common ingredient in week killers so there should not be much of a problem finding it.
Apply the weed kill killer according to the label directions. It may take several applications but this should be done very carefully, as this is not a selective product and will kill grass of many types.
Watch the area and reapply again as necessary. Bermuda grass grows from seed and through runners, so it may be a new generation that you are seeing when it comes back.
Use a pre-emergent herbicide, after using the glyphosate, if you are sure the problem is seeding grass and not invasion from other areas. This should take care of the problem of the grass reappearing after you have treated it.
Wait 30 days after applying glyphosate before you introduce your desired species. The area should receive several rain events during this time or be watered at least several times to help get rid of the herbicide.
