Myrtlewood, Alabama, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Well-matched crops include cabbage, fig, california poppy, and collard greens, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Myrtlewood, 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 Myrtlewood 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 Myrtlewood
Each reading below is measured for Myrtlewood itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsMyrtlewood runs about 274 days between hard freezes (read from Marengo County, the closest normal to Myrtlewood) — 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
MeasuredMyrtlewood 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 Myrtlewood is in
Myrtlewood sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Myrtlewood's own centroid rather than borrowed from Marengo County.

Is it too late to plant in Myrtlewood?
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 28; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 25 (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. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

A note from Gnorman
What an experienced grower watches for around here
In and around Myrtlewood, Underground Storage Tanks runs higher than the national average — 42 sites within ~10 miles of Myrtlewood. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Myrtlewood
Everything above resolves to Myrtlewood as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Marengo 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 Myrtlewood
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 Marengo 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 Myrtlewood
When does frost risk typically end in Myrtlewood?
The last hard freeze (28°F) in Myrtlewood typically lands around Feb 25, 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 18.
When is the first frost in Myrtlewood?
The first hard freeze (28°F) in Myrtlewood 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 274 days after the spring freeze cleared.
How long is the growing season in Myrtlewood?
Measured between 28°F hard freezes, Myrtlewood sees about 274 frost-free days — roughly Feb 25 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 18 to Nov 12, about 239 days.
Is the soil safe to grow vegetables in Myrtlewood?
The federal record around Myrtlewood is light — 49 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (42), the nearest Underground Storage Tanks record about 0.1 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Myrtlewood?
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.
