Del Aire, California, sits in USDA hardiness zone 10b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Crops well matched to these conditions include artichoke, meyer lemon, california poppy, and cabbage — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Del Aire, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Del Aire lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Del Aire
Each reading below is measured for Del Aire itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredDel Aire sits in USDA hardiness zone 10b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Del Aire is in

What an experienced grower watches for around here
In and around Del Aire, Brownfields runs higher than the national average — 12,513 sites within ~10 miles of Del Aire. That's not a problem with your land — it's information about it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside Del Aire
Everything above resolves to Del Aire as a whole — one PHZM band and one 28°F frost record, read across 645 acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Del Aire
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals, with the labelled statewide window where none resolves; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Del Aire
Is it too late to plant in Del Aire?
No — Del Aire has no 28°F killing freeze in the 30-year station record, so the growing season is year-round and there is no last-frost date to wait for. Planting is paced by rainfall, heat and daylength instead of by frost: start heat-lovers any month, and time cool-season crops (lettuce, brassicas, peas) for the cooler, wetter half of the year or for higher ground. Succession sowing every few weeks works all year, so the limit is what you can keep watered and harvested, not the calendar.
When does frost risk typically end in Del Aire?
It doesn't — Del Aire records no 28°F killing freeze at all across the 1991–2020 station record, so there is no spring frost date to plant after. Cold still matters with elevation: the higher you garden, the cooler the nights, and a few tropical crops sulk below about 60°F even where they never freeze.
How long is the growing season in Del Aire?
Year-round — the 1991–2020 station record for Del Aire contains no 28°F killing freeze, so there is no season to measure between freezes. What paces planting instead is heat, rainfall and daylength: the hottest, wettest stretch is the hard part for cool-season crops, not winter. Elevation is the one real exception — the higher you garden, the colder the nights get.
Is the soil safe to grow vegetables in Del Aire?
The federal record around Del Aire runs heavier than most — 14,178 documented sites, mostly Brownfields entries (12,513), the nearest Brownfields record under a tenth of a mile out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Everything above is measured at Del Aire's scale — its 10b band and its no killing freeze on record. Your yard writes its own version of Del Aire's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
