Generally — Most Areas
red maple (zones 3-9) partially overlaps with California (5a-11a). It can grow in zones 5-9 within the state.
Your yard isn't the whole zone.
California spans zones 5a-11a, 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 red maple against your parcel's actual hardiness, soil, and sun.

When to Plant Red Maple in California
The frost window
Across California, the last spring frost clears between Jan 15 and May 15, and the first fall frost lands between Oct 1 and Dec 31 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 139-day window you can count on — up to 350 days on a mild site in a kind year.
Frost tenderness
Red Maple is frost-tender — its listed minimum temperature is 44.6°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, red maple 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 — Mono 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
Red Maple wants 210+ frost-free days; a typical California site sees ~220 (NOAA Climate Normals). That leaves tight; use transplants and pick early-maturing cultivars.
Chill hours
Red Maple requires ~1000 chill hours (32-45°F dormancy window). California typically banks ~1050 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
Red Maple likes near-neutral soil (pH 4-6.5). That's the common-ground band across California's alluvial clay and sandy loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your California site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
California's soils run mostly loam, but SSURGO maps the series, texture, and drainage under your exact parcel — that map unit, not the state average, decides how red maple performs.

Red Maple in California — Quick Answer
- Verdict: Generally — Most Areas
- Plant Zones: 3-9 (USDA PLANTS Database)
- State Zones: 5a-11a (USDA ARS PHZM 2023)
- Growing Season: Jan 15 - May 15 to Oct 1 - Dec 31 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but California growers also need to think about:
Drought is a persistent challenge — irrigation is essential in most regions
Design the water system before the plants: drip lines plus a thick mulch layer run a full garden on surprisingly little water.
Wildfire risk affects rural and foothill properties
Keep plantings low, lean, and well-watered near structures — your extension office publishes firewise landscaping guides for your county.
Adobe clay soils in valleys drain poorly without amendment
Work in compost over seasons, or skip the fight with a raised bed — adobe's nutrients are excellent once drainage is solved.
Wide climate variation means plant selection is highly location-specific
Zones run 5a to 11a in one state — check your exact zone before trusting any statewide planting list.
Growing red maple here specifically
Red Maple sends deep roots and rates to zones 3–9, but much of California sits on slow-draining, restrictive ground (SSURGO hydrologic group D) that forks and stunts them.

Timing shifts within California
California isn't one climate. In Mono County, the last hard freeze (28°F) holds until about May 14 — roughly 64 days later than the recorded state median — so plant red maple 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
Red Maple draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
California Cooperative Extension
For California-specific cultivar recommendations, planting calendars, and pest pressure for red maple, the canonical source is UC Agriculture and Natural Resources. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Red Maple native to California?
Red Maple is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in California. It can still earn a place in a California garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Red Maple in California
When can I plant Red Maple in California?
California's last spring frost clears between Jan 15 and May 15, and the first fall frost lands between Oct 1 and Dec 31 (NOAA Climate Normals 1991-2020). Red Maple 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 Red Maple grown in across California?
California spans USDA hardiness zones 5a-11a (USDA ARS PHZM 2023). Red Maple carries a range of zones 3-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical California site have?
A typical California site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Red Maple needs 210+ 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 Mono, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Red Maple native to California?
Red Maple is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in California. It can still earn a place in a California garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Red Maple in California?
Red Maple prefers pH 4-6.5 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across California soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
