How To Kill Kikuyu In Buffalo Grass
By Todd Layt
Winter is the best time to kill Kikuyu in Buffalo grass. Kikuyu is still active in many parts of Australia, whilst the other grass types almost stop growing. Kikuyu can quickly overtake a lawn if not kept in check. If you have even a trace of Kikuyu, you will need to do one of the steps below for the next couple of winters until the Kikuyu is eradicated. If the Kikuyu gets too thick in Buffalo, the only way to get rid of it is to kill the whole lawn and start again, so it is worth taking the following advice.
Painting Kikuyu with a Round Up.

In Buffalo, the only answer is spot killing Kikuyu with Round Up. That means you can only get the Round Up on the plant you want to kill and must not get any on the lawn you want to keep. There are 3 ways to do this:
- Spray the spot where the Kikuyu is, knowing the patch that gets the Round Up on it will die. This will kill the Kikuyu, but also some of the Buffalo grass around it. The disadvantage to this is you will have large dead spots until the lawn regrows, and that can take some time in winter. It is probably better to wait until early spring to do this.
- In winter, after letting the Kikuyu grow taller for three weeks with no mowing, a better solution is to paint the Kikuyu with a paint brush, making sure you get none on the grass underneath. The best way is to get a piece of cardboard, put it under the Kikuyu and paint the Kikuyu with Round Up. The cardboard will stop the Round Up getting on any of the Buffalo lawn. You may need to do this again in 3 weeks, as some Kikuyu may be missed.
- Again, after letting the Kikuyu get taller than the rest of the lawn for 3 to 4 weeks, grab the runner in your hand and inject Round Up with a needle into the runner of the Kikuyu. Make sure you DO NOT stab or inject yourself. Inject each runner in a few spots. You may need to do this again in 3 weeks, as some Kikuyu may be missed. The advantage of this is that you absolutely get none on any of the desired lawn.
If there is too much Kikuyu, the whole Buffalo
lawn may need to be killed and new turf laid.
