Generally — Most Areas
bay laurel (zones 8-10) suits most of Arizona (5b-10b) — zones 8-10 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Arizona spans zones 5b-10b, 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 bay laurel against your parcel's actual hardiness, soil, and sun.

When to Plant Bay Laurel in Arizona
The frost window
Across Arizona, the last spring hard freeze (28°F) clears between Feb 1 and Apr 2, and the first fall hard freeze lands between Nov 13 and Dec 12 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 225-day window you can count on — up to 314 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
Bay Laurel overwinters from USDA zone 8 and warmer (NC State Extension Gardener Plant Toolbox; Missouri Botanical Garden Plant Finder), and Arizona runs as cold as zone 5, so it does not survive winter in the ground here. It is a woody plant rather than a crop you resow each spring, so neither a fall establishment date nor a harvest countdown describes it in Arizona — which is why this page gives neither. What it needs here is a way through winter, not a planting date.
Timing tuned to sub-state frost dates — Coconino 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
The zone check says bay laurel survives winter in part of Arizona, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Bay Laurel wants 120+ frost-free days; a typical Arizona site sees ~266 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Bay Laurel needs ~2000 GDD (base 50°F) to ripen. The state median runs ~3945 GDD (from PRISM 1991-2020 climate normals), so Arizona's typical season clears that easily.
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
Bay Laurel tolerates a wide pH range (pH 4.5-8.2) — 3.7 units, acid ground through alkaline — so soil acidity is rarely what limits it in Arizona. 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 and 6.5 — worth knowing before you decide whether a Arizona soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Arizona site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Arizona's soils run mostly sandy loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Bay Laurel needs about 59 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 bay laurel performs.

What Else to Consider for Bay Laurel in Arizona
Zone compatibility tells you about winter cold survival — but Arizona growers also need to think about:
Extreme heat exceeding 110F stresses most plants
Minimal rainfall requires drip irrigation
Caliche hardpan prevents root penetration without breaking through
Growing bay laurel here specifically
At ~365 days to harvest, bay laurel barely fits Arizona's ~266 frost-free days — there's little slack if spring runs cold.

What to actually do about these — and the constraints that apply to every Arizona grower, not just bay laurel — is covered on the Arizona growing guide.
Timing shifts within Arizona
Arizona isn't one climate. In Coconino County, the last hard freeze (28°F) holds until about May 15 — roughly 78 days later than the recorded state median — so plant bay laurel to your county's window, not the statewide date.
Bay Laurel needs about 120 days of frost-free season to complete its cycle. Even Coconino County — Arizona’s shortest season at 150 frost-free days — clears that by 30 days, so season length isn’t the constraint anywhere in Arizona. What varies is your own parcel.
Across Arizona’s 15 counties the frost-free season runs from 150 days in Coconino County to 345 days in Maricopa County — a spread of 195 days, which is why a single statewide planting date misleads. The median Arizona county sees 266 frost-free days, leaving bay laurel about 146 days of slack on a typical parcel — room for a second sowing where the season runs long.
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"). Bay Laurel's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Arizona Fits Best
Even within Arizona's zones 5b-10b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for bay laurel (USDA PHZM 2023):
Pollinator + Wildlife Value
Bay Laurel draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, bay laurel can only work that bloom inside Arizona's frost window — roughly 266 days, opening after the last 28°F freeze (Feb 1 - Apr 2) and closing at the first (Nov 13 - Dec 12), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Bay Laurel
On Growable Ground, Bay Laurel means Laurus nobilis — not to be confused with cherry laurel (Prunus laurocerasus) and California bay (Umbellularia californica). cherry laurel is toxic and not culinary — confirm the leaf is true Laurus nobilis before cooking with it.
Recommended Bay Laurel Varieties for Arizona
Arizona publishes no state variety trial for bay laurel, so we won't invent a "best for Arizona" list. Choose types rated to your USDA hardiness zone (5b-10b), and confirm winter survival and drainage against your own parcel.

For Arizona-specific cultivar recommendations, planting calendars, and pest pressure for bay laurel, the canonical source is University of Arizona Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Common Questions About Growing Bay Laurel in Arizona
When can I plant Bay Laurel in Arizona?
Arizona's last spring hard freeze (28°F) clears between Feb 1 and Apr 2, and the first fall hard freeze lands between Nov 13 and Dec 12 (NOAA Regional Climate Centers ACIS, 1991-2020). Bay Laurel overwinters only from USDA zone 8 and warmer, and Arizona runs as cold as zone 5, so it does not survive winter in the ground here — the question for Arizona growers is how to carry it through winter under cover, not which week to plant it.
What hardiness zone is Bay Laurel grown in across Arizona?
Arizona spans USDA hardiness zones 5b-10b (USDA ARS PHZM 2023). Bay Laurel carries a range of zones 8-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Arizona site have?
A typical Arizona site sees ~266 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Bay Laurel 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 Coconino, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Bay Laurel in Arizona?
Bay Laurel tolerates pH 4.5-8.2 and well (dry spells) drainage (FAO ECOCROP). That is a 3.7-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Arizona site — amend for drainage and organic matter first.
Will Bay Laurel actually grow on my specific land in Arizona?
