Getting Rid Of Bluegrass In Our Zoysia
Q: Can you please recommend a product and process for tackling clumps of bluegrass weed in our zoysia sod?
A: It’s almost impossible to selectively kill an undesirable grassy weed that’s growing in a desirable grass at this time of year. I’d carefully spot spray the bluegrass clumps with glyphosate and fertilize the zoysia twice this summer, in mid-May and in late July. Apply your preemergent in September.
