Gilmore, Maryland, sits in USDA hardiness zone 6b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
The conditions favor cabbage, hazelnut, lavender, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Gilmore, 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 Gilmore 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 Gilmore
Each reading below is measured for Gilmore itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredGilmore runs about 205 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredGilmore 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.

The kind of country Gilmore is in
Gilmore sits in the Central Appalachians — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Gilmore's own centroid, and it is not what its county reads: Allegany County is mostly Ridge and Valley. The wider page above you is answering a different question about different ground.

Is it too late to plant in Gilmore?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 11; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 8 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 30 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

Your land is one point inside Gilmore
Everything above resolves to Gilmore as a whole — one PHZM band and one 28°F frost record, read across 67 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 Gilmore
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 Gilmore’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 Gilmore
When does frost risk typically end in Gilmore?
The last hard freeze (28°F) in Gilmore typically lands around Apr 8, 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 Apr 29.
When is the first frost in Gilmore?
The first hard freeze (28°F) in Gilmore typically arrives around Oct 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 16, so the watching starts about Sep 30 — about 205 days after the spring freeze cleared.
How long is the growing season in Gilmore?
Measured between 28°F hard freezes, Gilmore sees about 205 frost-free days — roughly Apr 8 through Oct 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 29 to Oct 16, about 170 days.
Is the soil safe to grow vegetables in Gilmore?
The federal record around Gilmore is a meaningful one — 311 documented sites, mostly Underground Storage Tanks entries (181), the nearest Underground Storage Tanks record about 0.5 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 I protect my plants from frost in Gilmore?
From about Sep 30 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 30 (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 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Gilmore's scale — its 6b band and its 205-day season. Your yard writes its own version of Gilmore's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
