Sun Requirements

Tomatoes require full sun, with at least 6-8 hours of direct sunlight daily. Nebraska’s generally sunny summer days provide the necessary light for healthy tomato growth.

Starting Tomatoes Indoors

In areas like Omaha (Zone 5b), start tomato seeds indoors from March 15 to April 15. This timing ensures that seedlings are ready for transplanting outdoors in mid-May to early June, after the last frost has passed.

Transplanting Tomato Seedlings

Transplant seedlings outdoors from May 15 to June 1, once soil temperatures are consistently above 50°F. Space the seedlings 24-36 inches apart in rows at least 36 inches apart to ensure proper air circulation and sunlight exposure.

General Care and Maintenance

Watering:

  • Water deeply and consistently to keep the soil evenly moist. Nebraska’s hot summers can dry out the soil quickly, making regular watering essential.
  • Water at the base of the plants to prevent wetting the foliage, which helps reduce the risk of fungal diseases.

Fertilizing:

  • Apply a balanced fertilizer at planting and again when the first fruits begin to form. Adding compost to the soil before planting improves fertility and soil structure.

Pest and Disease Management:

  • Monitor for common pests like aphids, cutworms, and tomato hornworms. Nebraska’s climate can also increase the risk of fungal diseases, so it’s important to keep an eye on your plants.
  • Use organic or integrated pest management strategies to keep your plants healthy and free of pests.

Harvesting Tomatoes:

  • Harvest tomatoes when they are fully colored and firm. Frequent harvesting during Nebraska’s hot summer months helps prevent overripening and ensures the best quality fruit.
