Unlikely — Zone Mismatch
live oak (zones 7-10) does not overlap with South Dakota's zone range (4a-5b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Live Oak is hardy to zone 7, and the warmest ground in South Dakota is zone 5 — 2 zones short. Planted in open ground it will not survive a South Dakota winter. To grow it here, grow live oak in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

South Dakota is not one climate
South Dakota’s winter-low ladder runs across 66 counties, from zone 4 in Brown County to zone 5.5 in Custer County. That is 15°F between the two counties’ average coldest night — the difference between live oak overwintering in the ground and coming under cover.
The middle half of 66 counties runs 4.5–5 zones, with a median of 4.5 zones — a 1.5-zone span end to end.
Measured across 66 South Dakota counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Live Oak Stands in South Dakota
Live Oak is rated for zones 7–10 — a cold floor USDA puts at 0 to 10°F. No South Dakota county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about South Dakota winters, not about live oak.

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.

When to Plant Live Oak in South Dakota
The frost window
Across South Dakota, the last spring hard freeze (28°F) clears between Apr 22 and Apr 29, and the first fall hard freeze lands between Oct 9 and Oct 15 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 163-day window you can count on — up to 176 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
South Dakota runs as cold as USDA zone 4, and no sourced winter-hardiness floor is on record for live oak, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether live oak is a permanent planting or a replant-every-spring crop for you turns on your own zone within South Dakota; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Lawrence County, not the statewide average.
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 live oak does not survive a South Dakota winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on South Dakota under protection.
Frost-free days
Live Oak wants 150+ frost-free days; a typical South Dakota site sees ~168 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a tight window — use transplants and pick early-maturing cultivars.
Chill hours
Live Oak requires ~100 chill hours (32-45°F dormancy window). South Dakota typically banks ~2500 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
Live Oak likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across South Dakota's prairie loam and clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a South Dakota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells), excessive (dry/moderately dry). If your South Dakota site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
South Dakota's soils run mostly loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Live Oak needs about 19 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how live oak performs.

What Else to Consider for Live Oak in South Dakota
Zone compatibility tells you about winter cold survival — but South Dakota growers also need to think about:
Extreme cold and short growing season
Low rainfall in western SD
Wind exposure on the open prairie
Growing live oak here specifically
Live Oak needs pH 5.5–7.5; South Dakota's dominant loam soils may or may not deliver that, so your parcel's SSURGO map unit is the real test.
Start with a soil test on your own ground and adjust pH and texture to fit live oak's 5.5–7.5 range. How to handle it →
What to actually do about these — and the constraints that apply to every South Dakota grower, not just live oak — is covered on the South Dakota growing guide.
Timing shifts within South Dakota
South Dakota isn't one climate. In Lawrence County, the last hard freeze (28°F) holds until about May 12 — roughly 17 days later than the recorded state median — so plant live oak to your county's window, not the statewide date.
Live Oak needs about 150 days of frost-free season to complete its cycle. 65 of South Dakota’s 66 counties give it that outright. The tightest that does is Harding County at 152 frost-free days — 2 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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"). Live Oak's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Is Live Oak native to South Dakota?
Live Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in South Dakota. It can still earn a place in a South Dakota garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Live Oak in South Dakota
When can I plant Live Oak in South Dakota?
South Dakota's last spring hard freeze (28°F) clears between Apr 22 and Apr 29, and the first fall hard freeze lands between Oct 9 and Oct 15 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Live Oak, so this page does not state whether it overwinters in South Dakota 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 Live Oak grown in across South Dakota?
South Dakota spans USDA hardiness zones 4a-5b (USDA ARS PHZM 2023). Live Oak carries a range of zones 7-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical South Dakota site have?
A typical South Dakota site sees ~168 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Live Oak needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Lawrence, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Live Oak native to South Dakota?
Live Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in South Dakota. It can still earn a place in a South Dakota garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Live Oak in South Dakota?
Live Oak prefers pH 5.5-7.5 and well (dry spells), excessive (dry/moderately dry) drainage (FAO ECOCROP). That sits in the common-ground band across South Dakota soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
