Zoysia Sod – Watering Schedule

Q: We had zoysia sod installed recently. Can you recommend a watering schedule for our irrigation system this summer?

A: The correct answer is to water when the grass needs it. This may not be a predictable schedule. In other words, irrigating once per week this spring would have been a waste of water and a detriment to your lawn. We had plenty of rain for all lawns then, but our weather has been dry since early May. One way to schedule appropriate watering is to hire an irrigation contractor to install a soil moisture sensor, which will tell your irrigation controller when the grass needs water. I’m familiar with two brands of moisture sensors: UgMO  and the Rain Bird SMRT-Y system.
