A memorable winter storm hit the South and Southeast during holiday season. Our region avoided much of the Midwest and Northeast snowfall. Wind and freezing weather harmed our electricity grids and landscapes over time.
1
We start 2023 with many queries concerning grass and landscape damage and future moves. Before taking action, let's review previous events and understand how to restore plants after an unexpected freeze.
2
From December 22 to 23, much of the South experienced a 40°F drop in temperature. Many experienced severe winds and temperatures below 15°F for at least 32 hours during this quick decline.
3
Temperatures rarely exceeded 32°F for more than 80 hours in most regions. These factors caused major issues. Ice formation in plants punctures cell walls, causing freeze damage, and the region's temperatures were severe enough for this.
4
The quick decline made plants less able to internalize low-temperature stress defenses. Desiccation (drying) by wind can harm plants.
5
This cold weather causes widespread damage. Most warm-season turf grasses, like zoysia and Bermuda grass, had already entered winter dormancy, so damage won't show until spring.
