Sun Requirements

Tomatoes require full sun, with at least 6-8 hours of direct sunlight daily. Delaware’s summer climate generally provides sufficient sunlight for optimal tomato growth.

Starting Tomatoes Indoors

In areas like Dover (Zone 7a), start tomato seeds indoors from March 1 to April 1. This schedule prepares seedlings for outdoor transplanting from May 1 to May 31, once the risk of frost has passed.

Transplanting Tomato Seedlings

Transplant seedlings outdoors from May 1 to May 31. Ensure soil temperatures are consistently above 50°F. Space the seedlings 24-36 inches apart in rows that are at least 36 inches apart to allow for proper air circulation and sunlight exposure.

General Care and Maintenance

Watering:

  • Water deeply and consistently to maintain evenly moist soil. In Delaware’s humid climate, it’s crucial to manage moisture levels to prevent both drought stress and waterlogging.
  • Water at the base of the plants to reduce the risk of fungal diseases.

Fertilizing:

  • Apply a balanced fertilizer at planting and again when the first fruits set. Enriching the soil with compost before planting also helps to provide essential nutrients.

Pest and Disease Management:

  • Monitor for common pests like aphids, cutworms, and tomato hornworms.
  • Use organic pest control
