Mountain Pine, Arkansas, sits in USDA hardiness zone 8a — 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.
Even in Mountain Pine, no two yards are alike.

What this means for growing in Mountain Pine
Each reading below is measured for Mountain Pine itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredMountain Pine runs about 247 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredMountain Pine sits in USDA hardiness zone 8a.
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 Mountain Pine is in
Mountain Pine sits in the Ouachita Mountains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Mountain Pine's own centroid rather than borrowed from Garland County.

Is it too late to plant in Mountain Pine?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 15 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 17 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

What an experienced grower watches for around here
In and around Mountain Pine, Underground Storage Tanks runs higher than the national average — 233 sites within ~10 miles of Mountain Pine. That's not a problem with your land — it's information about it.
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 Mountain Pine
Everything above resolves to Mountain Pine as a whole — one PHZM band and one 28°F frost record, read across 1K 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 city 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 Mountain Pine
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Mountain Pine’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 city grain anywhere on this page — there is no city-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 Mountain Pine
When does frost risk typically end in Mountain Pine?
The last hard freeze (28°F) in Mountain Pine typically lands around Mar 15, 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 Apr 5.
When is the first frost in Mountain Pine?
The first hard freeze (28°F) in Mountain Pine typically arrives around Nov 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 3, so the watching starts about Oct 18 — about 247 days after the spring freeze cleared.
How long is the growing season in Mountain Pine?
Measured between 28°F hard freezes, Mountain Pine sees about 247 frost-free days — roughly Mar 15 through Nov 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 5 to Nov 3, about 212 days.
Is the soil safe to grow vegetables in Mountain Pine?
The federal record around Mountain Pine is a meaningful one — 329 documented sites, mostly Underground Storage Tanks entries (233), the nearest Toxics Release Inventory record about 0.3 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 Mountain Pine?
From about Oct 18 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 17 (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 17. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
