From Stephen K.
“HI Alex, I have a zoysia lawn in Northern Georgia and last season I started to get some tall fescue growing in different areas of the lawn thanks to my neighbor’s overseeding. I heard that using Atrazine could be a good product to use as I don’t want to hurt the Zoysia but still get rid of the fescue. Should I use Atrazine or something else?”
Hi Stephen, thanks for writing in. I don’t recommend you use Atrazine or a product that has Atrazine as the active ingredient since it will not be labeled as safe to use on Zoysia.
I like a product with Sulfosulfuron as the active ingredient such as a product called Certainty. This is labeled as a post-emergent and will kill off tall fescue as its growing, so apply it once you see it. It should work well in the winter (above 50 degrees) as well if you are wanting to keep fescue out of the dormant Zoysia.
This is also a good product to control Nutgrass as that is persistent in your area in spring.

Hi, Alex Kuritz here. Growing up I remember that my family had one of the best lawns in the neighborhood. Richly green and lush. I did a lot as I grew up in terms of caring and tending for not only my family’s lawn but also my neighbors. I can say I have years of experience, and I am here to share it with you.
