zoysia empire contaminated with sir walter

Question

We live in a warm climate and love our Empire zoysia turf. Problem is, as delivered, it came contaminated with some Sir Walter. So we have patches of broad leaf Sir Walter in our yard and it seems to be more invasive and is taking over. Can you recommend a method to kill off the Walter? Spray or otherwise?

Answer 1

Thanks for the response. Love the idea of using vinegar. We'll try a small test section to get the hang of it.

Answer 2

The article below will give you many natural methods on how to kill the Sir Walter grass invading your lawn. I would try these natural methods first before resorting to chemical measures. If none of these natural methods work, you could try spraying small areas of the Sir Walter with glyphosate but you run the risk of harming your zoysia turf in the process.
