What Grows in Old Bennington, Vermont

The last hard freeze (28°F) in Old Bennington typically lands around Apr 25, 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 May 16.

The first hard freeze (28°F) in Old Bennington typically arrives around Oct 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 3, so the watching starts about Sep 17 — about 175 days after the spring freeze cleared.

Measured between 28°F hard freezes, Old Bennington sees about 175 frost-free days — roughly Apr 25 through Oct 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 16 to Oct 3, about 140 days.

The federal record around Old Bennington runs heavier than most — 344 documented sites, mostly Underground Storage Tanks entries (172), the nearest Underground Storage Tanks 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.

From about Sep 17 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 Oct 17 (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 Oct 17. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
