In addition to cold tolerance, plant hardiness has been observed to be linked to how much stress specific plants are undergoing into the winter, or even how fast the onset of cold weather is in a specific year. This means that often stressed plants will exhibit less cold tolerance than plants that have been well maintained.
In 2012 the USDA updated their plant hardiness map based on 1976–2005 weather data, using a longer period of data to smooth out year-to-year weather fluctuations. [7] Two new zones (12 and 13) were added to better define and improve information sharing on tropical and semitropical plants, they also appear on the maps of Hawaii and Puerto Rico.
The Northern Plains' climate is semi-arid and is prone to drought, annually receiving between 16 and 32 inches (410 and 810 mm) of precipitation, and average annual snowfall ranging between 15 and 30 inches (380 and 760 mm), with the greatest snowfall amounts occurring in the Texas panhandle and areas near the border with New Mexico.

The National Oceanic and Atmospheric Administration has forecast a mild winter for Texans, with warmer-than-usual temperatures and less precipitation. NOAA's 2024-2025 winter forecast maps: What ...
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
When you get a break in the cold weather in the next several weeks apply a broadleafed herbicide containing 2,4-D to kill developing weeds such as dandelions, clover, henbit, chickweed, plantain ...
Texas sage is nicknamed the "barometer bush" due to a commonly held belief that it can predict the rain. According to folklore, the plant goes into bloom in anticipation of upcoming rain. It appears that the plant sometimes blooms because of humidity or low atmospheric pressure, which can occur before or after rain.
