Lake Sherwood, California, sits in USDA hardiness zone 10b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect artichoke, meyer lemon, california poppy, and cabbage to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Lake Sherwood, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Lake Sherwood lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Lake Sherwood
Each reading below is measured for Lake Sherwood itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredLake Sherwood sits in USDA hardiness zone 10b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Lake Sherwood is in
Lake Sherwood sits in the Southern California/Northern Baja Coast — EPA Level III, inside the wider Mediterranean California. That is read at Lake Sherwood's own centroid, and it is not what its county reads: Ventura County is mostly Southern California Mountains. The wider page above you is answering a different question about different ground.

What an experienced grower watches for around here
In and around Lake Sherwood, Brownfields runs higher than the national average — 1,260 sites within ~10 miles of Lake Sherwood. That's not a problem with your land — it's information about it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside Lake Sherwood
Everything above resolves to Lake Sherwood as a whole — one PHZM band and one 28°F frost record, read across 2K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Lake Sherwood
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals, with the labelled statewide window where none resolves; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Lake Sherwood
Is it too late to plant in Lake Sherwood?
No — Lake Sherwood has no 28°F killing freeze in the 30-year station record, so the growing season is year-round and there is no last-frost date to wait for. Planting is paced by rainfall, heat and daylength instead of by frost: start heat-lovers any month, and time cool-season crops (lettuce, brassicas, peas) for the cooler, wetter half of the year or for higher ground. Succession sowing every few weeks works all year, so the limit is what you can keep watered and harvested, not the calendar.
When does frost risk typically end in Lake Sherwood?
It doesn't — Lake Sherwood records no 28°F killing freeze at all across the 1991–2020 station record, so there is no spring frost date to plant after. Cold still matters with elevation: the higher you garden, the cooler the nights, and a few tropical crops sulk below about 60°F even where they never freeze.
How long is the growing season in Lake Sherwood?
Year-round — the 1991–2020 station record for Lake Sherwood contains no 28°F killing freeze, so there is no season to measure between freezes. What paces planting instead is heat, rainfall and daylength: the hottest, wettest stretch is the hard part for cool-season crops, not winter. Elevation is the one real exception — the higher you garden, the colder the nights get.
Is the soil safe to grow vegetables in Lake Sherwood?
The federal record around Lake Sherwood is a meaningful one — 1,385 documented sites, mostly Brownfields entries (1,260), the nearest Brownfields record about 0.4 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
Everything above is measured at Lake Sherwood's scale — its 10b band and its no killing freeze on record. Your yard writes its own version of Lake Sherwood's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
