The Growing Season refers to the number of days between the date of the last frost in the spring and the first frost in the fall. This is the part of the year when the weather conditions in a particular region, such as temperatures and rainfall, permit plant growth.
In Texas, the length of the growing season varies depending on location. The typical start date, or date of the last frost, ranges from January 1st, along the Gulf Coast, to April 15th in portions of the Texas Panhandle. The growing season ends on the date of the first frost of fall, which can occur between October 15th in the Texas High Plains and the end of December in the Coastal Plains.
