Montgomery County, in Alabama, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
The conditions favor cabbage, fig, california poppy, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Montgomery County lies within the Black Belt — a regional growing area with its own character.

Heat and winter chill in Montgomery County
Across a year, Montgomery County accumulates about 5,762 growing degree days above 50°F, about 478 more than the middle Alabama county — ahead of 57 of Alabama’s 67 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 944 hours below 45°F, 304 fewer than the Alabama middle of 1,248. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Montgomery County
Across Montgomery County, the ground is predominantly Inceptisols, where Sumter, Boswell, and Oktibbeha are the most extensive named soil series. The soil is generally well drained with a fine sandy loam surface. Topsoil pH runs about 5.0–6.7, moderately acidic. Rainfall drains through hydrologic group D soils.

How the ground varies across Montgomery County
The USDA soil survey maps 32% of Montgomery County as well drained — but another 67% drains differently: 27% moderately well drained, 25% somewhat poorly drained.
Sumter is the most extensive named soil at 11% of mapped acres, then Boswell (10%) and Oktibbeha (9%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Montgomery County
Each reading below is measured for Montgomery County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Montgomery County are well drained, in hydrologic group D — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Montgomery County runs about pH 5.0–6.7, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Wet ground
MeasuredAbout 15% of Montgomery County is mapped as hydric — wetland — soil.
If your lot falls in one of those pockets, a standard in-ground bed will fight waterlogging all season, and roots that need air will struggle.
Check how your own ground drains before you dig; raised beds or moisture-loving plantings turn a wet corner from a problem into a niche.
USDA NRCS SSURGO
Season length
MeasuredMontgomery County runs about 277 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.

Montgomery County sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Montgomery County
We scored all 1,086 plants against Montgomery County's own USDA zone 8b and its own 277-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Alabama profile.
Is it too late to plant in Montgomery County?
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 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 22 (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. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

What the federal record shows across Montgomery County — and how to grow with it.
We checked the federal record across Montgomery County — 1,385 documented sites across 7 of the 9 source types we track.
The most significant on record: 19 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Montgomery County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

What an experienced grower watches for around here
In and around Montgomery County, Superfund runs higher than the national average — 19 sites across Montgomery County. That's not a problem with your land — it's information about it.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Montgomery County
Everything above resolves to Montgomery County as a whole — one PHZM band and one county frost record, read across 503K 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 county 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 county average.

How we know this about Montgomery County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Montgomery County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Montgomery County
When does frost risk typically end in Montgomery County?
The last hard freeze (28°F) in Montgomery County typically lands around Feb 22, 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 15.
How long is the growing season in Montgomery County?
Measured between 28°F hard freezes, Montgomery County sees about 277 frost-free days — roughly Feb 22 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 15 to Nov 12, about 242 days.
Is the soil safe to grow vegetables in Montgomery County?
The federal record around Montgomery County is a meaningful one — 1,385 documented sites, mostly Underground Storage Tanks entries (691), the nearest Superfund record about 0.9 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.
