What this means for growing in Old Stine
Each reading below is measured for Old Stine itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsOld Stine runs about 319 days between hard freezes (read from Kern County, the closest normal to Old Stine) — 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
MeasuredOld Stine sits in USDA hardiness zone 9b.
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 Old Stine is in
Old Stine sits in the Central California Valley — EPA Level III, inside the wider Mediterranean California. That is read at Old Stine's own centroid rather than borrowed from Kern County.

Is it too late to plant in Old Stine?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 8 — 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 Old Stine, Brownfields runs higher than the national average — 2,703 sites within ~10 miles of Old Stine. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside Old Stine
Everything above resolves to Old Stine as a whole — one PHZM band, read across 395 acres, with hard-freeze dates borrowed from Kern County’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 Old Stine
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 Kern County’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 Old Stine
When does frost risk typically end in Old Stine?
The last hard freeze (28°F) in Old Stine typically lands around Jan 23, 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 Feb 13.
When is the first frost in Old Stine?
The first hard freeze (28°F) in Old Stine typically arrives around Dec 8, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 24, so the watching starts about Nov 8 — about 319 days after the spring freeze cleared.
How long is the growing season in Old Stine?
Measured between 28°F hard freezes, Old Stine sees about 319 frost-free days — roughly Jan 23 through Dec 8, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 13 to Nov 24, about 284 days.
Is the soil safe to grow vegetables in Old Stine?
The federal record around Old Stine is a meaningful one — 3,213 documented sites, mostly Brownfields entries (2,703), the nearest Brownfields record about 0.1 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 Old Stine?
From about Nov 8 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 8 (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 8. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
