What this means for growing in Woods Landing-Jelm
Each reading below is measured for Woods Landing-Jelm itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredWoods Landing-Jelm runs about 112 days between hard freezes — 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.

Winter hardiness
MeasuredWoods Landing-Jelm sits in USDA hardiness zone 4b.
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.

The kind of country Woods Landing-Jelm is in
Woods Landing-Jelm sits in the Southern Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Woods Landing-Jelm's own centroid, and it is not what its county reads: Albany County is mostly Wyoming Basin. The wider page above you is answering a different question about different ground.

Is it too late to plant in Woods Landing-Jelm?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Apr 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 28 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 17 — long-season crops need about 90 days of runway, quick greens only 30. Even here the calendar’s edges hold value: thirty-day greens late in the window, then garlic and a rested bed for spring.

What an experienced grower watches for around here
In and around Woods Landing-Jelm, two things run higher than the national average within ~10 miles of Woods Landing-Jelm — Mining (14 sites) and Nitrate (22 sites). That's not a problem with your land — it's information about it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Woods Landing-Jelm
Everything above resolves to Woods Landing-Jelm as a whole — one PHZM band and one 28°F frost record, read across 11K acres. 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 Woods Landing-Jelm
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 Woods Landing-Jelm’s own record; 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 Woods Landing-Jelm
When does frost risk typically end in Woods Landing-Jelm?
The last hard freeze (28°F) in Woods Landing-Jelm typically lands around May 28, 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 18.
When is the first frost in Woods Landing-Jelm?
The first hard freeze (28°F) in Woods Landing-Jelm typically arrives around Sep 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 3, so the watching starts about Aug 18 — about 112 days after the spring freeze cleared.
How long is the growing season in Woods Landing-Jelm?
Measured between 28°F hard freezes, Woods Landing-Jelm sees about 112 frost-free days — roughly May 28 through Sep 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 18 to Sep 3, about 77 days.
Is the soil safe to grow vegetables in Woods Landing-Jelm?
The federal record around Woods Landing-Jelm shows 40 documented sites, mostly Nitrate entries (22), the nearest Mining record about 0.8 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 Woods Landing-Jelm?
With about 112 frost-free days between hard freezes, Woods Landing-Jelm 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 140 to 168 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 28 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Woods Landing-Jelm's scale — its 4b band and its 112-day season. Your yard writes its own version of Woods Landing-Jelm's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
