What Grows in East Malta Colony, Montana

The last hard freeze (28°F) in East Malta Colony typically lands around May 1, 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 22.

The first hard freeze (28°F) in East Malta Colony typically arrives around Oct 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 17, so the watching starts about Sep 1 — about 153 days after the spring freeze cleared.

Measured between 28°F hard freezes, East Malta Colony sees about 153 frost-free days — roughly May 1 through Oct 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 22 to Sep 17, about 118 days.

The federal record around East Malta Colony is light — 6 documented sites across the 9 federal source types we checked, mostly Nitrate entries (2), the nearest Brownfields record about 6.2 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.

From about Sep 1 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 1 (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 1. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
