When to plant in Artesia, CA
USDA Zone 10aHere are the average frost dates, USDA hardiness zone, and a month-by-month planting calendar for Artesia, California — all computed from Artesia's nearest NOAA weather station.
Artesia's growing season is short at roughly -2 days, so succession planting is limited; lean on transplants over direct sowing for anything slow to mature. Heads up: the nearest complete-normals station is about 24 km from Artesia, so your yard's frost dates can differ — a low spot or a paved city center can shift them by a week. Zone 10a is warm enough that Artesia can grow subtropical perennials, and the short (or absent) frost period barely limits the annual calendar.
