Conditional — Some Areas
autumn olive (zones 3-8) has limited zone overlap with Nebraska (4a-5b). Only zones 4-5 in the state are suitable.
Your yard isn't the whole zone.
Nebraska spans zones 4a-5b, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score autumn olive against your parcel's actual hardiness, soil, and sun.

When to Plant Autumn Olive in Nebraska
The frost window
Across Nebraska, the last spring frost clears between Apr 15 and May 10, and the first fall frost lands between Sep 25 and Oct 15 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 138-day window you can count on — up to 183 days on a mild site in a kind year.
Frost tenderness
Autumn Olive is frost-tender — its listed minimum temperature is 41°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Establishment timing
As a long-lived plant, autumn olive isn't racing the calendar to a harvest date. Plant it in spring once the last-frost window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
Timing tuned to sub-state frost dates — Sioux County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Autumn Olive wants 120+ frost-free days; a typical Nebraska site sees ~170 (NOAA Climate Normals). That leaves a workable window — start indoors to bank time.
Growing degree days
Autumn Olive needs ~1800 GDD (base 50°F) to ripen. The state median runs ~3200 GDD (USDA NRCS county aggregates), so Nebraska's typical season clears that easily.
Chill hours
Autumn Olive requires ~500 chill hours (32-45°F dormancy window). Nebraska typically banks ~1350 chill hours per winter (MSU Extension method), which keeps this plant on track.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Autumn Olive likes near-neutral soil (pH 6-8.5). That's the common-ground band across Nebraska's loess and sandy loam (sandhills) — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Nebraska site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Nebraska's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel — that map unit, not the state average, decides how autumn olive performs.

Autumn Olive in Nebraska — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 3-8 (USDA PLANTS Database)
- State Zones: 4a-5b (USDA ARS PHZM 2023)
- Growing Season: Apr 15 - May 10 to Sep 25 - Oct 15 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Nebraska growers also need to think about:
Low western rainfall (15 inches) requires irrigation
In the west, drip lines and deep mulch are the season — design the water first and the garden follows.
Extreme wind exposure on open plains
A windbreak earns its ground: even a shrub row or a snow fence cuts plant stress dramatically.
Hail damage during severe storm season
Keep row cover or hail netting staged through the storm months — five minutes of cover can save the whole bed.
Growing autumn olive here specifically
Nebraska's soils run mostly silt loam (Mollisols), and whether that suits autumn olive's pH 6.0–8.5 preference comes down to your exact parcel, not the statewide picture.
Pull your parcel's SSURGO map unit, test pH, and amend toward autumn olive's 6.0–8.5 target before planting. How to handle it →
Timing shifts within Nebraska
Nebraska isn't one climate. In Sioux County, the last hard freeze (28°F) holds until about Apr 29 — roughly 28 days later than the recorded state median — so plant autumn olive to your county's window, not the statewide date.
County last-freeze dates: NOAA/PRISM Climate Normals 1991-2020, 28°F threshold (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Autumn Olive draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Nebraska Cooperative Extension
For Nebraska-specific cultivar recommendations, planting calendars, and pest pressure for autumn olive, the canonical source is Nebraska Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Autumn Olive native to Nebraska?
No — the USDA PLANTS Database lists Autumn Olive as introduced rather than native in the Lower 48, so it is not part of Nebraska's native flora. It grows here as a garden plant; pairing it with a few Nebraska natives keeps local pollinators fed too.

Common Questions About Growing Autumn Olive in Nebraska
When can I plant Autumn Olive in Nebraska?
Nebraska's last spring frost clears between Apr 15 and May 10, and the first fall frost lands between Sep 25 and Oct 15 (NOAA Climate Normals 1991-2020). Autumn Olive is a long-lived planting, so target spring just after your local last frost — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Autumn Olive grown in across Nebraska?
Nebraska spans USDA hardiness zones 4a-5b (USDA ARS PHZM 2023). Autumn Olive 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 Nebraska site have?
A typical Nebraska site sees ~170 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Autumn Olive needs 120+ 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 Sioux, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Autumn Olive native to Nebraska?
No — the USDA PLANTS Database lists Autumn Olive as introduced rather than native in the Lower 48, so it is not part of Nebraska's native flora. It grows here as a garden plant; pairing it with a few Nebraska natives keeps local pollinators fed too.
How should I amend the soil for Autumn Olive in Nebraska?
Autumn Olive prefers pH 6-8.5 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Nebraska soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
