Every figure names the dataset it came from. Hard-freeze dates are this town’s own 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.
Hardiness Zone Range
Zone 6b is Falcon Heights's average, not your lot's — a low corner or a tree line moves it. Against Falcon Heights's 140-day season, see what your own ground reads.
Your town runs its own season
Falcon Heights's own 30-year record measures about 140 days between 28°F killing freezes — 54 days longer than Klamath County's ~86. Both are measured records, not estimates.
That gap is the whole reason a county average can mislead here. Plant against Falcon Heights's ~140-day season rather than the county figure — and the sun, slope and cold-air drainage on your specific lot move it again.
NOAA Regional Climate Centers ACIS (1991–2020), 30-year daily minimum record. Both figures are measured records — this town’s own and its county’s. A town with no record of its own is absent here rather than estimated.

What this means for growing in Falcon Heights
Each reading below is measured for Falcon Heights itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredFalcon Heights runs about 140 days between hard freezes — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.

Winter hardiness
MeasuredFalcon Heights sits in USDA hardiness zone 6b.
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.
USDA PHZM 2023
The kind of country Falcon Heights is in
Falcon Heights sits in the Eastern Cascades Slopes and Foothills — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Falcon Heights's own centroid rather than borrowed from Klamath County.

Is it too late to plant in Falcon Heights?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 18; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 16 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 3 — long-season crops need about 90 days of runway, quick greens only 30. Short seasons reward decisiveness — quick-maturing varieties late, hardy greens under cover, and next year’s garlic in the ground before it closes.

What an experienced grower watches for around here
In and around Falcon Heights, two things run higher than the national average within ~10 miles of Falcon Heights — Underground Storage Tanks (206 sites) and Superfund (4 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Falcon Heights
Everything above resolves to Falcon Heights as a whole — and this is a town whose own 30-year record already runs a season its county’s does not. Your parcel sits at one point inside even that. 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 Falcon Heights
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 at Falcon Heights’s own record; 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 Falcon Heights
When does frost risk typically end in Falcon Heights?
The last hard freeze (28°F) in Falcon Heights typically lands around May 16, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Jun 6.
When is the first frost in Falcon Heights?
The first hard freeze (28°F) in Falcon Heights typically arrives around Oct 3, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 19, so the watching starts about Sep 3 — about 140 days after the spring freeze cleared.
How long is the growing season in Falcon Heights?
Measured between 28°F hard freezes, Falcon Heights sees about 140 frost-free days — roughly May 16 through Oct 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 6 to Sep 19, about 105 days.
Is the soil safe to grow vegetables in Falcon Heights?
The federal record around Falcon Heights is a meaningful one — 278 documented sites, mostly Underground Storage Tanks entries (206), the nearest CAFO record about 1.5 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.
How do gardeners stretch the season in Falcon Heights?
With about 140 frost-free days between hard freezes, Falcon Heights rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 168 to 196 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 16 hard-freeze normal stretches the season without touching the calendar.
