Every hardiness zone has its fans, but it’s easy to believe that Zone 8 isn’t one of the best for gardening. The growing season is quite long, long enough that you don’t have to worry about your crops maturing between the last spring frost date of April 1 and the first autumn frost date of December 1. While the exact dates vary a bit year to year, that is unquestionably a long growing season. But you should check for the exact dates before planting since they can vary each year by up to two weeks.

How cold is cold in USDA Zone 8? The average lowest winter temperatures range from 10 degrees F to 20 degrees F. Summers are warm to hot. Lots of trees, shrubs and vegetables grow happily in this zone. Here’s when to plant them.

January

January is a no-gardening month. That gives you the time to recover from the holidays and relax before starting to plant in February.

Let’s get started planting! In Zone 8, February is the month to start many vegetables. This is also a good time to do some tool maintenance before the growing season begins in earnest. Sharpen your pruners with the Corona sharpener, set up your seed starting kit with a Vivosun heat mat and Barrina grow lights, all available from Amazon.
