Gardening in California: What the Season Actually Allows
Late August in California means something different depending on whether you’re standing in a Eureka backyard fog bank or a Palm Springs patio hitting…
Home & garden, state by state
Everything we have worked out for California: what to plant and when, which varieties finish in time, the pests that actually turn up here, and the jobs that pay off month by month. We also cover the rest of the property, from lawns and soil to home care and energy, because a garden rarely stops at the vegetable bed.
The numbers first, because everything else follows from them. Measured at the weather station in Los Angeles, the last spring freeze falls around no freeze occurs in an average year and the first fall freeze falls around no freeze occurs in an average year, USDA zones 5a-11a, 4,719 growing degree days in the year.
Garlic is the awkward one: only 0 weeks below 40 °F, where it needs six to split into cloves. Chill the cloves before planting, or grow a softneck type.
Elsewhere on the property in California: the pests that turn up here.
Figures from NOAA's 1991-2020 climate normals. A state is not one climate: elevation, a large lake or the coast can move these dates by two weeks either way, so check your own county with the extension service before you spend money.
