Yes — Strong Match
loblolly pine (zones 6-9) covers every zone Mississippi contains (7b-9b), so hardiness is not what limits it anywhere in the state.

Mississippi is not one climate
Mississippi’s winter-low ladder runs across 82 counties, from zone 7.5 in Benton County to zone 9 in Wilkinson County. That is 15°F between the two counties’ average coldest night — the difference between loblolly pine overwintering in the ground and coming under cover.
The middle half of 82 counties runs 8–8.5 zones, with a median of 8.5 zones — a 1.5-zone span end to end.

When to Plant Loblolly Pine in Mississippi
The frost window
Across Mississippi, the last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 263-day window you can count on — up to 286 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Mississippi runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for loblolly pine, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether loblolly pine is a permanent planting or a replant-every-spring crop for you turns on your own zone within Mississippi; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says loblolly pine survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Loblolly Pine wants 300+ frost-free days; a typical Mississippi site sees ~273 (NOAA Regional Climate Centers ACIS, 1991-2020) — 27 days short of what it needs. A typical Mississippi season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Chill hours
Loblolly Pine requires ~200 chill hours (32-45°F dormancy window). Mississippi typically banks ~1160 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Loblolly Pine likes near-neutral soil (pH 4-6.5). That's the common-ground band across Mississippi's loess and alluvial clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 4.5 and 5.5 — worth knowing before you decide whether a Mississippi soil test result is a problem or just a number. Drainage matters: this plant wants poorly (saturated >50% of year), well (dry spells). If your Mississippi site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Loblolly Pine in Mississippi
Zone compatibility tells you about winter cold survival — but Mississippi growers also need to think about:
Extreme summer heat and humidity
Heavy alluvial clay in the Delta region
Frequent severe storms and flooding
What to actually do about these — and the constraints that apply to every Mississippi grower, not just loblolly pine — is covered on the Mississippi growing guide.
Timing shifts within Mississippi
Loblolly Pine needs about 300 days of frost-free season to complete its cycle. 2 of Mississippi’s 82 counties give it that outright. The tightest that does is Hancock County at 304 frost-free days — 4 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Mississippi’s 82 counties the frost-free season runs from 232 days in Tishomingo County to 309 days in Harrison County — a spread of 77 days, which is why a single statewide planting date misleads. The median Mississippi county sees 273 frost-free days, which is 27 days short of what loblolly pine needs — so on a typical Mississippi parcel this is a transplant-or-protect crop, not a direct-sow one.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Loblolly Pine's 300-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

For Mississippi-specific cultivar recommendations, planting calendars, and pest pressure for loblolly pine, the canonical source is Mississippi State University Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Loblolly Pine native to Mississippi?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Loblolly Pine as native to Mississippi. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Loblolly Pine in Mississippi
When can I plant Loblolly Pine in Mississippi?
Mississippi's last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Loblolly Pine, so this page does not state whether it overwinters in Mississippi and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Loblolly Pine grown in across Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Loblolly Pine carries a range of zones 6-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Mississippi site have?
A typical Mississippi site sees ~273 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Loblolly Pine needs 300+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Loblolly Pine native to Mississippi?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Loblolly Pine as native to Mississippi. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Loblolly Pine in Mississippi?
Loblolly Pine prefers pH 4-6.5 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Mississippi soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
