How to read this. The frost dates above are 50% probability dates: in half of the years in the 1991–2020 record, the last 32°F reading at this station came later than the date shown. If your garden is in a low spot, far from the airport, or at a different elevation (this station is at 299.3 m), shift the dates. The planner tool lets you type your own dates.

Each row applies a published extension rule to the frost dates above. Hardy crops go out 2–4 weeks before the last frost; semi-hardy crops 0–2 weeks before; tender crops around the frost date; very tender crops 2 or more weeks after. The last fall planting date counts the crop's days to harvest back from the first fall frost. The rules and their sources are on the methodology page.

What the Omaha, Nebraska frost-free season means for your choices

Omaha, NE planting questions

When is the last frost in Omaha, Nebraska?

The 50% probability date for the last spring 32°F reading at OMAHA EPPLEY AIRFIELD, NE US is Apr 21, from the NOAA 1991–2020 climate normals. In half the years on that record the last frost came later than that date, so tender crops are safer a week or two after it. The last 28°F hard freeze averages Apr 11.

When can I plant tomatoes in Omaha, Nebraska?

Tomatoes are a very tender crop, so the Colorado State Extension rule puts them out 2 or more weeks after the last spring frost: May 5 – May 19 in Omaha, Nebraska. Start the seeds indoors Mar 17 – Apr 14, which is 5 to 7 weeks before that transplant window.

How long is the growing season in Omaha, Nebraska?

Omaha, Nebraska averages 173 frost-free days, between the 50% last spring frost on Apr 21 and the 50% first fall frost on Oct 11 at OMAHA EPPLEY AIRFIELD, NE US. Check a variety's days to harvest against that number before buying seed.

When should I start seeds indoors in Omaha, Nebraska?

The earliest indoor sowing on this calendar is broccoli and cabbage at Feb 3 – Mar 3. Hardy crops are transplanted out Mar 24 – Apr 7 here, and each crop's indoor window is simply its outdoor window minus the transplant age published by Colorado State Extension, so nothing starts earlier than that.

What can I plant in fall in Omaha, Nebraska?

The crops with a separate fall sowing here, latest first, are radishes, spinach, kohlrabi, turnips, lettuce (leaf) and onions (green), plus 21 more on the chart above. Each fall date counts the crop's days to harvest back from the first fall frost on Oct 11, plus an allowance for frost-tolerant crops that is our own assumption, not the source's.
