Average Date Of Last Freeze
There’s a lot riding on the date of the last killing freeze or frost in any garden. Unfortunately, few of us can read the future, so we rely on averages to determine the dates. Mind you, if you plant a cold-sensitive plant on the precise date of the average last killing freeze, you have a 50 percent chance of losing it. Plant it 10 days earlier, and you increase those odds to probably 90 percent. Plant it 10 days later than the average date, and you probably improve your chances to 90 percent likelihood of success.
This is the map we included inside the back cover of this year’s Texas Gardening Calendar. We hope you find it useful.
