What Grows in Hitchcock County, Nebraska

Hitchcock County sits in USDA hardiness zone 6a, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.

For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Mar 3; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 31 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 1 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.

The last hard freeze (28°F) in Hitchcock County typically lands around Mar 31, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.

Measured between 28°F hard freezes, Hitchcock County sees about 215 frost-free days — roughly Mar 31 through Nov 1, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.

Hitchcock County's zone 6a supports a wide range — strong performers include Sweet Corn, Tomato, Cottonwood, Grape, and Sunflower. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.

Officially, Hitchcock County sits in USDA zone 6a (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.

The federal record around Hitchcock County is light — 32 documented sites across the 9 federal source types we checked — 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.

Start with three facts. Hitchcock County sits in USDA zone 6a, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 31, with about 215 frost-free days to work with (NOAA 1991–2020 climate normals); and the local federal record is light — 32 documented sites across the area we checked. From there, matching plants to your actual soil and sun is the fun part.
