Zone 8 Planting Guide

September

2020

Joel Grant

When to Start Planting According to Your Hardiness Zone

The United States is broken into 13 hardiness zones. Each zone has specific requirements for when certain plants should be started. The zones were created based on the area’s lowest average temperature. Zone 8 has a long growing season. In general, it lasts from April to December. Most vegetable varieties will be able to mature before the first frost date. For more information on what plants are suitable for zone 8 and when they should be started, check out our zone 8 graph below.
