Nebraska stretches from humid Falls City to the high, dry Panhandle, and the right week to plant tomatoes changes a lot across the state. Planting too early in cold soil stalls tomatoes for weeks. This guide explains when to plant tomatoes in Nebraska, region by region, using Nebraska Extension guidance on soil temperature and Nebraska State Climate Office frost dates.

When to plant tomatoes in Nebraska: the short answer

In most of Nebraska, tomatoes should not go outdoors until the threat of frost has passed, which Nebraska Extension says is typically around Mother’s Day. In eastern Nebraska (Omaha, Lincoln) that means Mother’s Day to mid-May. Central Nebraska is usually about a week later, and the Panhandle and west-central areas two to three weeks later, into late May or early June. Everywhere, wait for soil of at least 60°F at 4 inches and nights above 50°F.

Tomato planting dates by region

Frost dates are 1991 to 2020 averages (32°F) from the Nebraska State Climate Office. An average date still leaves about a 50% chance of a later frost, so planting a few weeks after it is safer. Start tomato seeds indoors 6 to 8 weeks before planting; see our Nebraska seed starting calendar.

Soil temperature and night temperature

• Soil at least 60°F. Nebraska Extension groups tomatoes with very tender crops that need soil of at least 60°F and daytime temperatures above 60°F. They do not tolerate cool or cold temperatures.
• Check real soil data. Nebraska Extension posts current 1-day and 7-day soil temperatures, measured 4 inches under bare soil, through CropWatch and the Nebraska State Climate Office. A soil thermometer in your own bed is even better.
• Nights above 50°F. Wait until night temperatures stay above 50°F before transplanting.
• Watch central Nebraska in mid-May. Nebraska Extension notes that a killing frost can still occur in central Nebraska up to about May 15.
• Protect from wind. Spring wind is hard on new transplants across the plains. Frost cloth or a temporary windbreak helps for the first week.

Tomato varieties for Nebraska

Nebraska summers swing from heavy rain to heat and drought, and those swings cause cracked fruit. Nebraska Extension lists these varieties as tolerant of fruit cracking:

In the Panhandle and north-central Nebraska, where the frost-free season is shorter, choose earlier-maturing varieties too. For more choices, see Nebraska Extension NebGuide G1896, Selected Vegetable Cultivars for Nebraska.

How to plant tomatoes in Nebraska

1. Harden off plants for 7 to 10 days, putting them outside on mild days and bringing them in on cold nights.
2. Check soil temperature 4 inches deep in the morning before planting.
3. Plant on a calm, cloudy day or in the evening to reduce transplant shock.
4. Bury the stem deep; tomatoes root along the buried stem.
5. Add cages or stakes at planting so you don’t damage roots later.
6. Water deeply and evenly, then mulch once the soil has warmed. Nebraska Extension recommends an even moisture supply and mulch to help prevent blossom end rot and cracking.

Conclusion

Plant tomatoes in eastern Nebraska around Mother’s Day to mid-May, in central Nebraska about a week later, and in the Panhandle and west-central areas in late May to early June. Wait for 60°F soil at 4 inches and nights above 50°F, choose crack-tolerant varieties, and keep watering even through the summer.
