What this means for growing in Graymoor-Devondale

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

Season length

Measured

Graymoor-Devondale runs about 235 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

Measured

Graymoor-Devondale sits in USDA hardiness zone 7a.

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 Graymoor-Devondale is in

Graymoor-Devondale sits in the Interior Plateau — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Graymoor-Devondale's own centroid rather than borrowed from Jefferson County.

Is it too late to plant in Graymoor-Devondale?

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 Feb 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 13 — 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.

A note from Gnorman

What an experienced grower watches for around here

In and around Graymoor-Devondale, two things run higher than the national average within ~10 miles of Graymoor-Devondale — Underground Storage Tanks (1,661 sites) and Toxics Release Inventory (163 sites). 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.

Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.

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

Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Graymoor-Devondale

Everything above resolves to Graymoor-Devondale as a whole — one PHZM band and one 28°F frost record, read across 474 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 city 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 Graymoor-Devondale

The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Graymoor-Devondale’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 city grain anywhere on this page — there is no city-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 Graymoor-Devondale

When does frost risk typically end in Graymoor-Devondale?

The last hard freeze (28°F) in Graymoor-Devondale typically lands around Mar 23, 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 13.

When is the first frost in Graymoor-Devondale?

The first hard freeze (28°F) in Graymoor-Devondale typically arrives around Nov 13, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 30, so the watching starts about Oct 14 — about 235 days after the spring freeze cleared.

How long is the growing season in Graymoor-Devondale?

Measured between 28°F hard freezes, Graymoor-Devondale sees about 235 frost-free days — roughly Mar 23 through Nov 13, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 13 to Oct 30, about 200 days.

Is the soil safe to grow vegetables in Graymoor-Devondale?

The federal record around Graymoor-Devondale is a meaningful one — 2,321 documented sites, mostly Underground Storage Tanks entries (1,661), the nearest Underground Storage Tanks 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 Graymoor-Devondale?

From about Oct 14 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 13 (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 13. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
