The primary factor in Bermuda and Zoysia spring green-up is the soil temperature. Bermuda and Zoysia thrive in hot summer temperatures. When soil temperatures at 4" reach 75-80 degrees, it creates optimum root growth. When the soil temperature reaches 80-90 degrees, we have optimum shoot growth. Why do soil temperatures matter?Current daily average soil temperatures are in the upper 20s and lower 30s for most of Nebraska, at the 4-inch depth. Even though air temperatures set record lows this week, the abundant snowpack and soil moisture (for most), kept soil temperatures warmer than one might expect. This may benefit over-wintering crops, but also pest survival.
