What this means for growing in Manley Hot Springs
Each reading below is measured for Manley Hot Springs itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsManley Hot Springs runs about 118 days between hard freezes (read from Yukon-Koyukuk Census Area, the closest normal to Manley Hot Springs) — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredManley Hot Springs sits in USDA hardiness zone 2b.
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.

Is it too late to plant in Manley Hot Springs?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Apr 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 15 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 10 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

Your land is one point inside Manley Hot Springs
Everything above resolves to Manley Hot Springs as a whole — one PHZM band, read across 35K acres, with hard-freeze dates borrowed from Yukon-Koyukuk Census Area’s record because no 30-year normal resolves at this town’s own centroid. 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 Manley Hot Springs
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 at Yukon-Koyukuk Census Area’s record, because none resolves here; 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 Manley Hot Springs
When does frost risk typically end in Manley Hot Springs?
The last hard freeze (28°F) in Manley Hot Springs typically lands around May 15, 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 Jun 5.
When is the first frost in Manley Hot Springs?
The first hard freeze (28°F) in Manley Hot Springs typically arrives around Sep 10, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 27, so the watching starts about Aug 11 — about 118 days after the spring freeze cleared.
How long is the growing season in Manley Hot Springs?
Measured between 28°F hard freezes, Manley Hot Springs sees about 118 frost-free days — roughly May 15 through Sep 10, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 5 to Aug 27, about 83 days.
Is the soil safe to grow vegetables in Manley Hot Springs?
The federal record around Manley Hot Springs shows 16 documented sites, mostly Mining entries (9), the nearest Underground Storage Tanks record about 1.1 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do gardeners stretch the season in Manley Hot Springs?
With about 118 frost-free days between hard freezes, Manley Hot Springs rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 146 to 174 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 15 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Manley Hot Springs's scale — its 2b band and its 118-day season. Your yard writes its own version of Manley Hot Springs's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
