Unlikely — Zone Mismatch
live oak (zones 8-10) does not overlap with Rhode Island's zone range (6b-7b). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Live Oak is hardy to zone 8, and the warmest ground in Rhode Island is zone 7 — 1 zone short. Planted in open ground it will not survive a Rhode Island winter. To grow it here, grow live oak in a hoop house or unheated greenhouse — its modeled 1.5-zone lift covers this gap.

Where Live Oak Stands in Rhode Island
Live Oak is rated for zones 8–10 — a cold floor USDA puts at 10 to 20°F. No Rhode Island 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 Rhode Island winters, not about live oak.

Winter cold is the limit here — the same plant works in a container that comes under cover.
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 Rhode Island
The frost window
Across Rhode Island, the last spring hard freeze (28°F) clears between Mar 27 and Apr 3, and the first fall hard freeze lands between Nov 7 and Nov 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 218-day window you can count on — up to 239 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
Rhode Island runs as cold as USDA zone 6, 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 Rhode Island; 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 live oak does not survive a Rhode Island 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 Rhode Island under protection.
Chill hours
Live Oak requires ~100 chill hours (32-45°F dormancy window). Rhode Island 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 Rhode Island's glacial till and sandy loam — 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 Rhode Island soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells), excessive (dry/moderately dry). If your Rhode Island site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.
Your land, not the state average
Rhode Island's soils run mostly fine sandy 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 Rhode Island
Zone compatibility tells you about winter cold survival — but Rhode Island growers also need to think about:
Small lot sizes limit garden space in much of the state
Salt spray affects coastal plantings
Rocky glacial soils need clearing
Growing live oak here specifically
Live Oak needs pH 5.5–7.5; Rhode Island's dominant fine sandy 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 Rhode Island grower, not just live oak — is covered on the Rhode Island growing guide.
Where in Rhode Island Live Oak Is Zone-Hardy
Live Oak is rated for USDA zones 8–10. No Rhode Island county reaches it. Even Washington County, the state’s mildest winter at zone 7a, sits below the plant’s zone 8 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Live Oak’s zone 8–10 band: Rated hardy to zone 8a by NC State Extension Gardener Plant Toolbox, checked Oct 2026. Ceiling: NC State Extension Gardener Plant Toolbox (read 2026-10-05).. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Is Live Oak native to Rhode Island?
Live Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Rhode Island. It can still earn a place in a Rhode Island garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Live Oak in Rhode Island
When can I plant Live Oak in Rhode Island?
Rhode Island's last spring hard freeze (28°F) clears between Mar 27 and Apr 3, and the first fall hard freeze lands between Nov 7 and Nov 21 (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 Rhode Island 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 Rhode Island?
Rhode Island spans USDA hardiness zones 6b-7b (USDA ARS PHZM 2023). Live Oak is listed for zones 8-10, which do not overlap them, so there is no zone in Rhode Island where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
How many frost-free days does a typical Rhode Island site have?
A typical Rhode Island site sees ~225 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.
Is Live Oak native to Rhode Island?
Live Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Rhode Island. It can still earn a place in a Rhode Island garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Live Oak in Rhode Island?
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 Rhode Island soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
