Zone 9 Planting Guide

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 9 has a long growing season. In general, it lasts from February to November. If you live in zone 9, we recommend starting seeds indoors before the first frost date. Knowing when to transplant these seeds will be key to having a successful harvest For more information on what plants are suitable for zone 9 and when they should be started, check out our zone 9 graph below.
