Avon, Alabama, sits in USDA hardiness zone 9a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Crops well matched to these conditions include artichoke, fig, california poppy, and cabbage — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Avon, no two yards are alike.

What this means for growing in Avon
Each reading below is measured for Avon itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsAvon runs about 296 days between hard freezes (read from Houston County, the closest normal to Avon) — 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
MeasuredAvon sits in USDA hardiness zone 9a.
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.
USDA PHZM 2023
The kind of country Avon is in
Avon sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Avon's own centroid rather than borrowed from Houston County.

Is it too late to plant in Avon?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 13; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 10 (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 Avon, two things run higher than the national average within ~10 miles of Avon — CAFO (5 sites) and Underground Storage Tanks (296 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Avon
Everything above resolves to Avon as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Houston 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 Avon
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 Houston 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 Avon
When does frost risk typically end in Avon?
The last hard freeze (28°F) in Avon typically lands around Feb 10, 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 3.
When is the first frost in Avon?
The first hard freeze (28°F) in Avon 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 296 days after the spring freeze cleared.
How long is the growing season in Avon?
Measured between 28°F hard freezes, Avon sees about 296 frost-free days — roughly Feb 10 through Dec 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 3 to Nov 19, about 261 days.
Is the soil safe to grow vegetables in Avon?
The federal record around Avon is a meaningful one — 447 documented sites, mostly Underground Storage Tanks entries (296), the nearest Underground Storage Tanks record about 0.7 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 Avon?
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.
