Killing weeds in Buffalo grass has always been a major concern for homeowners. While quite safe for many lawn types, the active ingredient in many lawn weed killers was often Dicamba, which would damage or even kill the grass when it was used on a Buffalo lawn.
These days we have many more choices which are readily available to effectively kill weeds in Buffalo grass lawns. We simply need to be aware that we need to purchase a product which is clearly labelled as safe for use on Buffalo grass.
If the product is not clearly labelled as safe for Buffalo grass, then we can do a simple check on the label for the active ingredient in the herbicide:
- MCPA and Bromoxynil based herbicides are generally safe for use on Buffalo grass.
- Dicamba based herbicides are never safe for use on Buffalo grass.
Yates Lush Weed Killer
Yates Lush is our preferred weed killer for use on Buffalo grass. It uses the safe active ingredients of MCPA and Bromoxynil to effectively kill many weed types safely in Buffalo grass, and the product is manufactured by a highly respected herbicide company which manufactures products for home use.
Yates Lush will effectively control bindii, clover, jo-jo, catsear, cudweed, dandelion, plantains, thistles, creeping oxalis, capeweed, creeping buttercup and Canadian fleabane in Buffalo grass.
Applying Buffalo Grass Weed Killer
Yates Lush weed killer is a concentrated herbicide which will need to be diluted in a handy sprayer with water. Dilution and application ratios are printed clearly on the packaging.
Warning - do not apply more herbicide or mix the herbicide any stronger than manufacturers recommendations, too much herbicide can still damage any lawn type, not just Buffalo grass.
Repeat Applications of Lawn Herbicide
Some weeds can be quite robust, and therefore difficult to eradicate in a single spray, other weed types will have masses of seeds already in the soil, and therefore will continue to produce more weeds, even though the last lot were killed.
If weeds re-emerge after spraying, or some weeds still remain alive, repeat the weed spraying again in another 2 weeks.
Do Not Spray Weeds After Lawn Mowing
As with all weed killers, never spray any herbicide on a lawn within a week of it's last lawn mowing. The open wounds created from mowing will quickly absorb any herbicide, and will quickly damage or kill any lawn type, not just Buffalo.
It's also a great idea to never mow the lawn until one week after mowing, this allows ample time for the weeds to take up the herbicide before it is removed with lawn mowing.
Professional Buffalo Weed Spraying
Some weed types can be extremely difficult to eradicate in a Buffalo grass lawn. If you're experiencing ongoing weed control problems in your Buffalo lawn, then it may be wise to hire a professional and licensed weed spraying contractor.
A professional weed spraying contractor will have expert knowledge and access to chemicals to treat weeds that the homeowner cannot access by law. In these cases, we highly recommend the homeowner hire a professional spraying contractor, and one who guarantees his work!
