Zone 9a includes the Deep South (Houston, New Orleans, Tampa, Phoenix lowlands, San Diego), coastal California, and southern Texas. Winter temperatures rarely fall below 20°F, and the 240–270 day growing season is long enough for year-round vegetable production. This is one of the few zones where you can grow tropical crops like citrus, avocado, and mango outdoors — and still succeed with warm-season vegetables almost year-round.
