Q
I have Buffalo grass growing in my Couch lawn, is there anyway I can kill the Buffalo grass and keep the Couch?A
Buffalo grass is highly intolerant of broadleaf weed killers with the active ingredient called Dicamba, and as a result of it's application - the Buffalo grass most often dies. However, Dicamba is perfectly safe for Couch lawns.
Purchase some broadleaf weed killer which is often marketed as Bindii and Clover killer, and mix it and apply it to the entire lawn by following manufacturers recommendations. Be sure to choose a herbicide which is Dicamba based. The packaging should have a warning that the weed killer should never be used on Buffalo grass.
Monitor the results of the weed spraying, and within a week or two the Buffalo grass should be dead, along with many weeds in the lawn too.
If the Buffalo survives, then simply apply a repeat application of herbicide at a timeframe recommended on the product packaging. This will usually be between 1-2 weeks.
Alternatively, the Buffalo grass can be spot treated by very carefully applying Glyphosate herbicide directly onto the leaves of the Buffalo. just be extremely careful not to spill any Glyphosate onto any other areas of lawn, as this herbicide will kill almost any plant it comes into contact with. A small paintbrush is usually a very good applicator.
