Zoysia Grass – Scalp and Image Herbicide

Q: I was wondering in what order and when should I apply Image herbicide and scalp my zoysia grass.

A: I believe the label for Image herbicide says that it should not be used when grass is greening up, which is beginning now. That means you can either apply the herbicide or scalp, but not both. Zoysia should not be scalped until it is at least 50% green: it is too early now.
