Buffalo grass can be quite good at outcompeting many weed types. However, once a buffalo lawn begins to lose some of its health and vigour, then many weed types can invade the turf very quickly and very abundantly. In this buffalo weeds article we'll cover some of the best and most effective means of killing buffalo lawn weeds as quickly possible. While tackling all weed types in proper order.
Fertilise The Lawn First
Before beginning weed treatments, we want to fertilise the lawn first. This will achieve 2 different desired results for us. First it will increase the success rate of the weed killers by a large degree, and second is it promotes the health and vigour of the turf to help bring it back to full health faster, thus allowing the turf to naturally outcompete weeds on its own.
Fertilise the lawn 3 to 7 days before beginning weed treatments.
Kill Majority Of Weeds First
The biggest family of weeds are called broadleaf weeds. The term "broadleaf weeds" refers to characteristics which many weed types have in common. Many different weeds can fall into this category such as Bindii, Clover, Catsear, Dandelion and many many others.
Because so many weed types fall into the category of broadleaf weeds, these are the weeds we will want to target first with a broadleaf weed killer designed for safe use on buffalo grass.
Using a buffalo broadleaf herbicide, which will cost around $15.00, the solution is diluted in water in a large spray bottle with a wand attachment for spraying. The weed spray is then applied to the buffalo lawn as per manufacturers guidelines, being careful not to apply too much, nor too little… so be sure to measure the lawn before mixing the required herbicide.
TIP: Yates Buffalo Pro is a high quality buffalo safe weed killer.
Second Application Of Broadleaf Herbicide
Within 2 to 3 weeks we'll begin to see our weeds dying off. But we can't rest on our achievements just yet. A closer look at the turf will reveal some younger weeds emerging, and some weed types that were sprayed - are still not dying.
This is normal.
Broadleaf weeds such as Oxalis can require 3 to 4 treatments to control.
We want to apply a second application of buffalo safe herbicide 2 to 3 weeks after the first. This will give a double hit for those harder to kill weeds which improves the chances of killing them, plus it will kill off those younger weeds very quickly as well.
If we have winter grass in the buffalo lawn, then once we've allowed our buffalo lawn to rest for a at least a few weeks from the last weed treatment, its time to treat and kill the winter grass.
Wintergrass weed killer should be mixed in a watering can as per manufacturers recommendations, and applied to the lawn. The herbicide is then watered into the lawn where it interacts with the roots of wintergrass to kill the weed.
Wintergrass can only be treated pre-emergent in May, or otherwise in June or July, once past these months the plant will become too mature and too strong and will easily resist all treatment methods
More Difficult Weeds
Once we have the majority of weeds under control, its time to tackle some of the more difficult weed types which may require specialist weed sprays or other treatments.
Weeds such as Nutgrass can now be treated, being very careful to allow the lawn to rest and recover between different weed treatments.
Kikuyu Grass In Buffalo
Kikuyu invasions in buffalo grass can be treated any time throughout this entire process. This is because we do not use a weed spray on the Kikuyu which would otherwise go into the soil or onto the rest of the buffalo turf.
Instead Kikuyu will need to be carefully hand painted with Glyphosate weed killer. We do this by mixing the Glyphosate in a sturdy and safe container, wearing rubber gloves and dipping our gloved hand into the weed killer and gently wiping over the Kikuyu… alternatively we can use a small paint brush to carefull paint the roots and stems of the Kikuyu grass... being very careful not to spill any Glyphosate onto the lawn!. Because Glyphosate will kill any plant or lawn it comes into contact with.

Bring The Buffalo Lawn Back To Health
These weed treatments will effectively kill the majority of weeds in heavily infested buffalo lawns. We just need to be careful to space out the treatments to allow the turf enough time to recover between these poisons being applied to it.
While undertaking these weed treatments, we should also be actively trying to bring the lawn back to full health, which simply involves following good lawn care practices.
Because a strong healthy buffalo lawn will naturally fight off many weed types on its own.
We began by fertilising the turf. Be sure to follow up this fertilising every 2 months afterwards using a good quality lawn fertiliser with trace elements.
Mow the lawn regularly, as this promotes green leaf growth, and removes many seeds from many weed types before they have an opportunity to reinfect our lawns.
Check watering, that the lawn is receiving enough water, as well as not too much water. Aiming to water the lawn deeply and less often. An application of wetting agents will also help the lawn soil distribute water throughout its profile far more effectively too.
Finally, check and rectify any other factors which may be leading to poor buffalo lawn health. Reduce cars or other foot traffic to the turf if necessary, remove excess shade, and check and rectify water logging or other issues, and we'll soon bring our buffalo lawn back to full health once again and naturally fighting off weeds all on its own.
