Why Zoysiagrass Greens Up Late

Zoysia may stay brown until June due to:

• Early scalping (wait for 60 °F soil)
• Early nitrogen (wait for 65 °F soil)
• Thick thatch insulating soil
• Large Patch disease
• Previous fertilizer/herbicide misapplication
• Erratic winter/spring temperature swings
• Off-type ‘Emerald’ sod (e.g., ‘BK-7’) that greens slower

Dr. Clint Waltz’s research explains the genetic off-type issue. Patience and proper timing usually resolve it.
