Q: How can I stop the infestation of Mexican primrose into my Bermuda lawn?Β Not knowing how invasive this plant can be, I placed several on a slope next to a grass area. Plants have now started growing in the grass.
A:Β Since Mexican primrose is a broadleaf plant, you can either pull it up as you see it or you can use a broadleaf herbicide to keep it out of your lawn area by spot treating where you see it coming up.
There are many broadleaf herbicides available and some are packaged with nonselective chemicals that also kill grass, like glyphosate.
It is important to read the label to make sure you are not also getting something that will kill your lawn and to make sure you understand the safety precautions for applying it.
