What this means for growing in New Kingman-Butler
Each reading below is measured for New Kingman-Butler itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredNew Kingman-Butler runs about 272 days between hard freezes — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredNew Kingman-Butler sits in USDA hardiness zone 8b.
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 New Kingman-Butler?
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 Jan 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What an experienced grower watches for around here
In and around New Kingman-Butler, Mining runs higher than the national average — 121 sites within ~10 miles of New Kingman-Butler. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside New Kingman-Butler
Everything above resolves to New Kingman-Butler as a whole — one PHZM band and one 28°F frost record, read across 3K 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 New Kingman-Butler
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 New Kingman-Butler’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 New Kingman-Butler
When does frost risk typically end in New Kingman-Butler?
The last hard freeze (28°F) in New Kingman-Butler typically lands around Feb 27, 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 Mar 20.
When is the first frost in New Kingman-Butler?
The first hard freeze (28°F) in New Kingman-Butler typically arrives around Nov 26, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 12, so the watching starts about Oct 27 — about 272 days after the spring freeze cleared.
How long is the growing season in New Kingman-Butler?
Measured between 28°F hard freezes, New Kingman-Butler sees about 272 frost-free days — roughly Feb 27 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 20 to Nov 12, about 237 days.
Is the soil safe to grow vegetables in New Kingman-Butler?
The federal record around New Kingman-Butler runs heavier than most — 393 documented sites, mostly Underground Storage Tanks entries (168), the nearest Underground Storage Tanks record about 0.7 miles 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.
How do I protect my plants from frost in New Kingman-Butler?
From about Oct 27 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 Nov 26 (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 Nov 26. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
