What this means for growing in Bladensburg

Each reading below is measured for Bladensburg itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length

Measured

Bladensburg runs about 190 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.

Buying weeks at each end

NOAA 1991–2020 Climate Normals

Winter hardiness

Measured

Bladensburg 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.

Is it too late to plant in Bladensburg?

Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Mar 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 24 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

A note from Gnorman

What an experienced grower watches for around here

In and around Bladensburg, Underground Storage Tanks runs higher than the national average — 31 sites within ~10 miles of Bladensburg. That's not a problem with your land — it's information about it.

Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.

Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Bladensburg

Everything above resolves to Bladensburg as a whole — one PHZM band and one 28°F frost record, read across 211 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 Bladensburg

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 Bladensburg’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 Bladensburg

When does frost risk typically end in Bladensburg?

The last hard freeze (28°F) in Bladensburg typically lands around Apr 17, 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 8.

When is the first frost in Bladensburg?

The first hard freeze (28°F) in Bladensburg typically arrives around Oct 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 10, so the watching starts about Sep 24 — about 190 days after the spring freeze cleared.

How long is the growing season in Bladensburg?

Measured between 28°F hard freezes, Bladensburg sees about 190 frost-free days — roughly Apr 17 through Oct 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 8 to Oct 10, about 155 days.

Is the soil safe to grow vegetables in Bladensburg?

The federal record around Bladensburg is light — 42 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (31), the nearest Underground Storage Tanks record under a tenth of a mile 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 Bladensburg?

From about Sep 24 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 24 (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 24. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
