Zone 9 Planting Calendar

USDA zone 9 has hot summers and mild, nearly frost-free winters, with an average annual minimum of 20-30°F and a growing season well over nine months. The limiting factor is summer heat, not cold, which inverts the calendar so cool-season crops flourish fall through spring while only heat-lovers persist in midsummer.

Last Spring Frost: Feb 28 First Fall Frost: Dec 5 280-Day Growing Season

States & regions in Zone 9: Central & coastal California, Gulf Coast (Houston, New Orleans area), Central & North Florida, Southern Texas, Southern Louisiana, Coastal Georgia & South Carolina (Lowcountry), Southern Arizona (low desert valleys)

What to Plant by Season in Zone 9

The right crops and methods for each season, based on zone 9's climate and frost timing.

What to Plant in Spring

Spring in zone 9 is a fast, productive window between the late-February frost and the brutal heat that arrives by June, so warm-season crops should go in early and the last cool-season greens are squeezed in before they bolt. Get heat-lovers transplanted by mid-March to set fruit before summer night temperatures shut down pollination.

What to Plant in Summer

Zone 9 summers are dominated by oppressive heat and humidity (or desert intensity) that halts most planting and stresses fruit set, so the season is mostly about maintaining spring-planted heat-lovers and growing only the toughest tropical crops. Use shade cloth, deep mulch, and consistent water; many gardeners take a partial break in July-August.
