|A tenant recently thatched our lawn, which is zoya (spelling?) grass and seeded it with Bermuda grass. We want to undo the damage, keeping the zoya and getting rid of Bermuda. We think the lawn was seeded about 2 months ago. How can we go about this? It's taken 20 years for the zoya to take over. Thanks for your help!|
|As you have seen, zoysia is a slow grower. So if the Bermuda grass has a chance to germinate and take hold, it could outcompete with the zoysia. Because they are both grass species, herbicides intended for use on broad leaf weeds will not work. Also, pre-emergent herbicides, that prevent weed seeds from germinating, won't be of use because the seeds have already begun growing.
This is a tough one, and I'm sorry that I can't help. You might consider contacting a local lawn care professional and see what they recommend,
