Plant fruit trees about a month before the first killing frost in the fall, or a month after the last killing frost of the winter. Killing temperatures range from 15 to 31 degrees Fahrenheit, depending on the species of fruit tree. Frost tolerance decreases as the flowers and fruit develop.
Using freezing temperatures of 29 to 32 F (minus 2 to 0 degrees Celsius), the average first date for frost in the city of Victoria is November 5, and the average last date is April 19.
There's a 50 percent chance of frost after the last average frost date and before the first average frost date. Check the average frost date for your area, and the frost tolerance of the fruit tree species. Plan on frost protection methods, such as covering trees, irrigation, light bulbs, and antitranspirants, for unexpected frosts.
