What this means for growing in Parker City

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

Season length

Measured

Parker City runs about 196 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

Measured

Parker City 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 Parker City is in

Parker City sits in the Eastern Corn Belt Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Parker City's own centroid rather than borrowed from Randolph County.

Is it too late to plant in Parker City?

Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 14; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 11 (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. As the window narrows, the plantings just get faster — fall brassicas, then greens, then garlic to finish.

What an experienced grower watches for around here

In and around Parker City, two things run higher than the national average within ~10 miles of Parker City — Toxics Release Inventory (25 sites) and Superfund (5 sites). That's not a problem with your land — it's information about it.

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

Superfund: Superfund sites represent the most severe contamination in the federal system.

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

Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Parker City

Everything above resolves to Parker City as a whole — one PHZM band and one 28°F frost record, read across 368 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 Parker City

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 Parker City’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 Parker City

When does frost risk typically end in Parker City?

The last hard freeze (28°F) in Parker City typically lands around Apr 11, 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 2.

When is the first frost in Parker City?

The first hard freeze (28°F) in Parker City 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 196 days after the spring freeze cleared.

How long is the growing season in Parker City?

Measured between 28°F hard freezes, Parker City sees about 196 frost-free days — roughly Apr 11 through Oct 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 2 to Oct 10, about 161 days.

Is the soil safe to grow vegetables in Parker City?

The federal record around Parker City is a meaningful one — 291 documented sites, mostly Underground Storage Tanks entries (178), the nearest Brownfields record under a tenth of a mile 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 Parker City?

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.
