What Grows in Pine Mountain Lake, California

The last hard freeze (28°F) in Pine Mountain Lake typically lands around Mar 12, 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 Apr 2.

The first hard freeze (28°F) in Pine Mountain Lake typically arrives around Nov 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 14, so the watching starts about Oct 29 — about 261 days after the spring freeze cleared.

Measured between 28°F hard freezes, Pine Mountain Lake sees about 261 frost-free days — roughly Mar 12 through Nov 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 2 to Nov 14, about 226 days.

The federal record around Pine Mountain Lake runs heavier than most — 72 documented sites, mostly Brownfields entries (34), the nearest Brownfields record about 0.2 miles 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.

From about Oct 29 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 Nov 28 (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 Nov 28. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
