Zoysia has been a very poor performer in North Florida. It has been touted as drought resistant which may be true… It can recover from drought stress. However in order to keep it green requires a lot of water. As you increase the water you also increase the opportunity for fungus so in our area we have seen lots of fungus problems turf turning brown then trying to be recovered From fungus because the clients water so much to recover it. It is also succeptible to mole crickets and billbugs. Zoysia also goes through ebbs and flows… It looks great and then it looks bad it looks great again and then it looks bad again. We tell our clients to avoid it.
As a sports turf construction company in Florida we’ve had experience with this quite a bit. We’ve had a lot of companies switch to other types of grass or artificial turf for exactly the reasons you had mentioned above. Let me know if you have any questions
