When to plant potatoes in Nebraska.
Sow between Mar 21 to Apr 23 in a typical year, keyed to Nebraska's median last frost around Apr 28. A second, fall sowing fits Jun 18 to Jul 1. Dates below are state medians; your ZIP code shifts them by days to weeks.

Potatoes dates for a typical Nebraska season.
Direct sow
Mar 21 to Apr 23
Keyed to the ~Apr 28 last frost. Sow 4" deep, 12" apart.
Fall round
Jun 18 to Jul 1
Counted back from the ~Oct 6 first frost.
Harvest
~90 days later
~3 lb per plant over ~1 weeks.
Nebraska spans more than one climate: Zone 5 is the most common zone, but the state runs 4b to 5b. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Nebraska growing notes
A hailstorm that would flatten a leafy crop and end its harvest in an afternoon barely touches a Nebraska potato, because the part worth keeping was never above ground to begin with.
Foliage Takes the Hit; the Tubers Never Know
A seed potato piece goes into the ground about 4 inches deep, and everything a grower harvests grows from underground stems off that piece, swelling into tubers below the soil. The deep loess that underlies much of Nebraska is about as good a medium as a tuber gets: expanding sideways into that loose, silty ground, a potato meets little resistance, so tubers tend to size up smooth and round instead of forking the way they can in tight clay. A summer hailstorm that shreds the leafy top looks devastating the day it happens, torn leaves and broken stems down the row, but the tubers sitting inches down are untouched. A plant with any green growth left usually pushes new leaves back out and keeps bulking what it already started, a setback rather than a lost crop, unlike a leafy crop with its harvest exposed.
Keeping soil mounded around the base as the plant grows matters for a different reason: light, not frost. A tuber that pushes up near the surface and catches sun turns green, and green skin means the tuber has started producing a bitter compound that makes it unfit to eat. Hilling keeps developing tubers buried in the dark where they belong, and it is easier work in this loose ground than in a heavy clay that resists a hoe.
Spring Does the Heavy Lifting; Fall Is the Harder Bet
With about 90 days needed to size up and a frost-free stretch running close to 161, there is room in theory for two full rounds, but in practice spring carries most of the state's potato crop. A spring-planted piece does its heaviest bulking in the cooler stretch before the state's hot, dry summer wind sets in for good, finishing ahead of the weather that stresses a plant still filling out tubers.
A fall planting is the harder bet. It asks a seed piece to sprout in soil that is often still hot and dry from summer rather than cool and damp the way spring ground is, and whatever time that slower start costs comes straight out of the days left before frost. Growers who take the fall route usually hold seed pieces in a cool, dark spot through the hottest weeks instead, which keeps a piece sound and dormant rather than letting it shrivel or rot in summer heat before it ever goes in the ground.
Reading the Vines: Beetle, Blight, and a Problem Aphids Carry Rather Than Cause
Colorado potato beetle is hard to mistake for anything else up close: a rounded, honey-colored adult with black stripes down its wing covers, laying tidy clusters of bright orange-yellow eggs on leaf undersides that hatch into humpbacked, brick-red larvae doing most of the actual feeding. A vine stripped of much of its leaf area before the tubers finish sizing loses yield right along with the leaves, since the canopy feeds what is growing underground. Checking leaf undersides through early summer and crushing any egg cluster found there catches the problem early.
Late blight moves fastest through a planting during a stretch of wet, humid weather, water-soaked dark lesions spreading across leaves and stems until a vine can collapse quickly, a threat that shows up far more over the state's humid eastern counties than toward the drier panhandle. Aphids matter here less for what they eat and more for what they carry: because a potato crop is usually replanted from a piece of last year's own harvest, a virus an aphid introduces this season can ride along in the saved seed and show up as a smaller, weaker stand the year after, with no aphids anywhere in sight by then. Starting with certified disease-free seed potatoes heads off most of that risk before planting.
In Nebraska: watch for
The pests that find potatoes here.
A middle-length season, about 161 frost-free days, means potato overlaps colorado potato beetle for a stretch each summer. Check plants every week or two and treat early.
Striped beetles and orange grubs eating the leaves.
Organic fix: Handpick adults, crush the orange egg clusters, dust with diatomaceous earth.
Dark greasy blotches after cool, wet spells.
Organic fix: Pull infected plants fast, keep leaves dry, use neem as a preventive.
Common scab
Rough, corky patches on the skin, raised on some tubers and sunk into pits on others.
Organic fix: Keep the bed evenly moist through the weeks right after tubers set, rotate away from potatoes, and pick a scab-resistant variety next time.
Your season math: Nebraska gives potatoes about 161 frost-free days, and it needs roughly 90 days to a first harvest. It's a one-planting crop, so time that single sowing well.
