Moore, Idaho, sits in USDA hardiness zone 4b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Expect cabbage, cranberry, cilantro, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Moore, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Moore lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Moore
Each reading below is measured for Moore itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredMoore runs about 123 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredMoore 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 Moore is in
Moore sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Moore's own centroid rather than borrowed from Butte County.

Is it too late to plant in Moore?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Apr 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 24 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Moore, Nitrate runs higher than the national average — 46 sites within ~10 miles of Moore. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
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 Moore
Everything above resolves to Moore as a whole — one PHZM band and one 28°F frost record, read across 182 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 city 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 Moore
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Moore’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 city grain anywhere on this page — there is no city-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 Moore
When does frost risk typically end in Moore?
The last hard freeze (28°F) in Moore typically lands around May 24, 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 14.
When is the first frost in Moore?
The first hard freeze (28°F) in Moore typically arrives around Sep 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 10, so the watching starts about Aug 25 — about 123 days after the spring freeze cleared.
How long is the growing season in Moore?
Measured between 28°F hard freezes, Moore sees about 123 frost-free days — roughly May 24 through Sep 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 14 to Sep 10, about 88 days.
Is the soil safe to grow vegetables in Moore?
The federal record around Moore shows 77 documented sites, mostly Nitrate entries (46), the nearest Nitrate record under a tenth of a mile 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 Moore?
With about 123 frost-free days between hard freezes, Moore 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 151 to 179 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 24 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Moore's scale — its 4b band and its 123-day season. Your yard writes its own version of Moore's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
