Every figure names the dataset it came from. Hard-freeze dates are this town’s own 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.
Hardiness Zone Range
Zone 8b is Stallion Springs's average, not your lot's — a low corner or a tree line moves it. Against Stallion Springs's 280-day season, see what your own ground reads.
Your town runs its own season
Stallion Springs's own 30-year record measures about 280 days between 28°F killing freezes — 39 days shorter than Kern County's ~319. Both are measured records, not estimates.
That gap is the whole reason a county average can mislead here. Plant against Stallion Springs's ~280-day season rather than the county figure — and the sun, slope and cold-air drainage on your specific lot move it again.
NOAA Regional Climate Centers ACIS (1991–2020), 30-year daily minimum record. Both figures are measured records — this town’s own and its county’s. A town with no record of its own is absent here rather than estimated.

What this means for growing in Stallion Springs
Each reading below is measured for Stallion Springs itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredStallion Springs runs about 280 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredStallion Springs 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.

The kind of country Stallion Springs is in
Stallion Springs sits in the Central California Foothills and Coastal Mountains — EPA Level III, inside the wider Mediterranean California. That is read at Stallion Springs's own centroid, and it is not what its county reads: Kern County is mostly Central California Valley. The wider page above you is answering a different question about different ground.

Is it too late to plant in Stallion Springs?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 29; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 3 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

What an experienced grower watches for around here
In and around Stallion Springs, two things run higher than the national average within ~10 miles of Stallion Springs — PFAS (5 sites) and Nitrate (28 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
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 Stallion Springs
Everything above resolves to Stallion Springs as a whole — and this is a town whose own 30-year record already runs a season its county’s does not. Your parcel sits at one point inside even that. 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 Stallion 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 Stallion Springs’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.

Common questions about Stallion Springs
When does frost risk typically end in Stallion Springs?
The last hard freeze (28°F) in Stallion Springs typically lands around Feb 26, 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 19.
When is the first frost in Stallion Springs?
The first hard freeze (28°F) in Stallion Springs typically arrives around Dec 3, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 19, so the watching starts about Nov 3 — about 280 days after the spring freeze cleared.
How long is the growing season in Stallion Springs?
Measured between 28°F hard freezes, Stallion Springs sees about 280 frost-free days — roughly Feb 26 through Dec 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 19 to Nov 19, about 245 days.
Is the soil safe to grow vegetables in Stallion Springs?
The federal record around Stallion Springs is a meaningful one — 83 documented sites, mostly Brownfields entries (38), the nearest Brownfields record about 0.5 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Stallion Springs?
From about Nov 3 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 Dec 3 (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 Dec 3. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
