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 honeylocust 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.

Where in Mississippi Fits Best
Honeylocust is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Against Mississippi’s 82 counties that band holds in 31 of them, and the line runs at Benton County (zone 7b), the coldest county still inside it.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Mississippi's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for honeylocust (USDA PHZM 2023):

When to Plant Honeylocust 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 honeylocust, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether honeylocust 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 honeylocust survives winter in part of Mississippi, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Chill hours
Honeylocust requires ~800 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
Honeylocust tolerates a wide pH range (pH 4.5-9) — 4.5 units, acid ground through alkaline — so soil acidity is rarely what limits it in Mississippi. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 8 — worth knowing before you decide whether a Mississippi soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Mississippi site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

What Else to Consider for Honeylocust 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 honeylocust — is covered on the Mississippi growing guide.
Where in Mississippi Honeylocust Is Zone-Hardy
Honeylocust is rated for USDA zones 3–8. 31 of Mississippi’s 82 counties fall inside that band. The coldest that does is Benton County at zone 7b. 51 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Mississippi decides this one.
Across those 82 counties Mississippi’s winter-low ladder runs from zone 7b in Benton County to zone 9a in Wilkinson County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Tishomingo County holds its last hard freeze (28°F) until about Mar 23, while Harrison County is clear by Feb 4 — 47 days apart. Set honeylocust out on your county’s date, not the state’s.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost".

Pollinator + Wildlife Value
Honeylocust draws honeybees and native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, honeylocust can only work that bloom inside Mississippi's frost window — roughly 273 days, opening after the last 28°F freeze (Feb 17 - Mar 3) and closing at the first (Nov 21 - Nov 30), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Is Honeylocust native to Mississippi?
The USDA PLANTS Database (accessed 2026-10-19) lists Honeylocust as native to the Lower 48 and records it growing in Mississippi, but it does not say whether those Mississippi plants are native or introduced. Your state's native plant society or Cooperative Extension can tell you whether it is part of the local flora.

Common Questions About Growing Honeylocust in Mississippi
When can I plant Honeylocust 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 Honeylocust, 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 Honeylocust grown in across Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Honeylocust carries a range of zones 3-8, 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). Honeylocust needs 180+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Honeylocust native to Mississippi?
The USDA PLANTS Database (accessed 2026-10-19) lists Honeylocust as native to the Lower 48 and records it growing in Mississippi, but it does not say whether those Mississippi plants are native or introduced. Your state's native plant society or Cooperative Extension can tell you whether it is part of the local flora.
How should I amend the soil for Honeylocust in Mississippi?
Honeylocust tolerates pH 4.5-9 and well (dry spells) drainage (FAO ECOCROP). That is a 4.5-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Mississippi site — amend for drainage and organic matter first.
Will Honeylocust actually grow on my specific land in Mississippi?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores honeylocust against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
