California spans USDA Plant Hardiness Zones 5a through 11b, covering a wide range of climates—from cold mountain regions to warm coastal and desert areas. Most of the state falls within Zones 7–10, while the warmest southern and coastal areas reach Zones 11a and 11b. Understanding USDA Plant Hardiness Zone 9 Zone 9 offers a favorable climate, with average annual minimum temperatures between 20°F and 30°F, and includes regions such as California, Texas, Florida, and the Gulf Coast.What Are California Planting Zones? California spans several USDA hardiness zones, ranging from Zone 5 in high mountain regions to Zone 11, with average minimum temperatures varying from -20°F to 45°F (-28. C to 7. C), depending on the region.The warmest zone in the 48 contiguous states is the Florida Keys (11b) and the coldest is in north-central Minnesota (2b). A couple of locations on the northern coast of Puerto Rico have the warmest hardiness zone in the United States at 13b.The gardening zones in zone 9 are zone 9a and 9b. Plants in zone 9a will tolerate minimum temperatures of no lower than 20 to 25 degrees Fahrenheit. In 9b, the lowest temperature for flowers or plants should be 25 to 30 degrees Fahrenheit.Each USDA hardiness zone has 10 degrees of minimum average temperature difference and is divided into two sections, a and b. Zones 7a and 7b both have a medium-length growing season. Zone 7a’s minimum average temperature is 0 to 5 degrees, and Zone 7b’s minimum average temperature is 5 to 10 degrees.

When to plant bulbs in zone 9b in California?
Average planting times for spring bulbs: September to October — Zones 4 and 5. October to early November — Zones 6 and 7. November to early December — Zones 8 and 9.

Zone 3 is 10 degrees F colder than Zone 4, etc. In addition, each zone is split in half. For example, sites in Zone 4a reach an average low temperature of -30 to -25 F, while sites in Zone 4b reach an average winter low temperature of -25 to -20 F.
