Webster County, in Nebraska, sits in USDA hardiness zone 5b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Crops well matched to these conditions include cabbage, cranberry, lavender, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.

Heat in Webster County
Across a year, Webster County accumulates about 3,118 growing degree days above 50°F, about 278 more than the middle Nebraska county — ahead of 71 of Nebraska’s 93 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

How the ground varies across Webster County
The USDA soil survey maps 90% of Webster County as well drained — but another 9% drains differently: 3% excessively drained, 3% somewhat excessively drained.
Holdrege is the most extensive named soil at 39% of mapped acres, then Hobbs (16%) and Geary (10%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Webster County
Each reading below is measured for Webster County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Webster County are well drained, in hydrologic group C — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Webster County runs about pH 6.2–6.9, close to neutral.
This is the range most vegetables prefer — one correction you probably do not have to make, which is genuinely good news for a new bed.
Keep it there with compost rather than lime or sulfur, and only amend if your own soil test says otherwise.
USDA NRCS SSURGO
Season length
MeasuredWebster County runs about 186 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
MeasuredWebster County sits in USDA hardiness zone 5b.
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.

What Grows in Webster County
We scored all 1,086 plants against Webster County's own USDA zone 5b and its own 186-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Nebraska profile.
Is it too late to plant in Webster County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Mar 19; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 16 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 19 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.
What gets applied to farmland in Webster County
USGS estimates 235,493 lb of Glyphosate on Webster County farmland in 2019, its largest by weight, ahead of Acetochlor (137,072 lb) and Acephate (54,953 lb).

What the federal record shows across Webster County — and how to grow with it.

The most significant on record: 3 concentrated animal feeding operations. Large-scale animal operations that can contaminate soil and groundwater with nitrates and pathogens.
The federal record across Webster County is light. Growing food here starts from a strong position — a quick pass over the map tells you whether any recorded site sits near your land, and if one does, that's information to plant with, not a reason to stop.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

Your land is one point inside Webster County
Everything above resolves to Webster County as a whole — one PHZM band and one county frost record, read across 368K 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 county 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 county average.

How we know this about Webster County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Webster County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Webster County
When does frost risk typically end in Webster County?
The last hard freeze (28°F) in Webster County typically lands around Apr 16, 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 7.
How long is the growing season in Webster County?
Measured between 28°F hard freezes, Webster County sees about 186 frost-free days — roughly Apr 16 through Oct 19, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 7 to Oct 5, about 151 days.
Is the soil safe to grow vegetables in Webster County?
The federal record around Webster County is light — 20 documented sites across the 9 federal source types we checked, mostly Nitrate entries (8), the nearest CAFO record about 2.3 miles 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.
