What Grows in Paradise Park, California

The last hard freeze (28°F) in Paradise Park typically lands around Jan 17, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 7.

The first hard freeze (28°F) in Paradise Park typically arrives around Dec 16, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 2, so the watching starts about Nov 16 — about 333 days after the spring freeze cleared.

Measured between 28°F hard freezes, Paradise Park sees about 333 frost-free days — roughly Jan 17 through Dec 16, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 7 to Dec 2, about 298 days.

The federal record around Paradise Park is a meaningful one — 949 documented sites, mostly Brownfields entries (804), the nearest Brownfields record about 0.5 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.

From about Nov 16 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 16 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 16. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
