Brandon, Colorado, sits in USDA hardiness zone 6a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Crops well matched to these conditions include cabbage, blackberry, california poppy, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Brandon, 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 Brandon 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 Brandon
Each reading below is measured for Brandon itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBrandon runs about 178 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredBrandon sits in USDA hardiness zone 6a.
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 Brandon is in
Brandon sits in the High Plains — EPA Level III, inside the wider Great Plains. That is read at Brandon's own centroid, and it is not what its county reads: Kiowa County is mostly Southwestern Tablelands. The wider page above you is answering a different question about different ground.

Is it too late to plant in Brandon?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 24; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 16 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

A note from Gnorman
What an experienced grower watches for around here
In and around Brandon, Nitrate runs higher than the national average — 22 sites within ~10 miles of Brandon. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Brandon
Everything above resolves to Brandon as a whole — one PHZM band and one 28°F frost record, read across 75 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 Brandon
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 Brandon’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 Brandon
When does frost risk typically end in Brandon?
The last hard freeze (28°F) in Brandon typically lands around Apr 21, 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 May 12.
When is the first frost in Brandon?
The first hard freeze (28°F) in Brandon typically arrives around Oct 16, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 2, so the watching starts about Sep 16 — about 178 days after the spring freeze cleared.
How long is the growing season in Brandon?
Measured between 28°F hard freezes, Brandon sees about 178 frost-free days — roughly Apr 21 through Oct 16, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 12 to Oct 2, about 143 days.
Is the soil safe to grow vegetables in Brandon?
The federal record around Brandon is light — 25 documented sites across the 9 federal source types we checked, mostly Nitrate entries (22), the nearest Nitrate record about 4.0 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Brandon?
From about Sep 16 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Oct 16 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Oct 16. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Brandon's scale — its 6a band and its 178-day season. Your yard writes its own version of Brandon's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
