What this means for growing in Seven Corners
Each reading below is measured for Seven Corners itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredSeven Corners runs about 243 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.

Winter hardiness
MeasuredSeven Corners sits in USDA hardiness zone 7b.
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 Seven Corners is in
Seven Corners sits in the Piedmont — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Seven Corners's own centroid rather than borrowed from Fairfax County.

Is it too late to plant in Seven Corners?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 19 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Your land is one point inside Seven Corners
Everything above resolves to Seven Corners as a whole — one PHZM band and one 28°F frost record, read across 436 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 Seven Corners
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 Seven Corners’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 Seven Corners
When does frost risk typically end in Seven Corners?
The last hard freeze (28°F) in Seven Corners typically lands around Mar 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 Apr 11.
When is the first frost in Seven Corners?
The first hard freeze (28°F) in Seven Corners typically arrives around Nov 19, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 5, so the watching starts about Oct 20 — about 243 days after the spring freeze cleared.
How long is the growing season in Seven Corners?
Measured between 28°F hard freezes, Seven Corners sees about 243 frost-free days — roughly Mar 21 through Nov 19, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 11 to Nov 5, about 208 days.
Is the soil safe to grow vegetables in Seven Corners?
The federal record around Seven Corners is a meaningful one — 5,329 documented sites, mostly Underground Storage Tanks entries (2,883), the nearest Brownfields record about 0.2 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 Seven Corners?
From about Oct 20 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 Nov 19 (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 Nov 19. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
