Overseeding Zoysia with Creeping Red Fescue: Not Recommended

Q: Can I overseed my zoysia backyard with creeping red fescue to keep it green this winter?

A: I doubt you'll get the results you want. Creeping red fescue needs close soil contact to germinate. Dense zoysia grass will catch the seed on its leaves, preventing soil contact. If you mow zoysia low enough to expose soil, the zoysia will likely suffer substantial winter-kill. Some overseed bermudagrass with annual ryegrass, which is more successful because bermudagrass foliage is less dense. Use a pre-emergent to keep cool-season weeds out of your zoysia lawn and enjoy its brown winter color.
