Sun Requirements
Tomatoes in Oklahoma require full sun, needing at least 6-8 hours of direct sunlight daily. The state’s hot summers provide ample sunlight, but managing heat stress is crucial for tomato health.
Starting Tomatoes Indoors
In areas like Oklahoma City (Zone 7a), start tomato seeds indoors from February 15 to March 15. This early start allows the seedlings to be ready for transplanting outdoors from mid-April to mid-May, once the threat of frost has passed.
Transplanting Tomato Seedlings
Transplant seedlings outdoors from April 15 to May 15, ensuring that soil temperatures are consistently above 60°F. Space the seedlings 24-36 inches apart in rows 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. Oklahoma’s hot summers can cause the soil to dry out quickly, so regular watering is 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 can improve fertility and help retain moisture in Oklahoma’s often sandy soils.
Pest and Disease Management:
- Monitor for common pests like aphids, cutworms, and tomato hornworms. The humid climate can also increase the risk of fungal diseases, so vigilance is key.
- Use organic or integrated pest management strategies to protect your plants from pests and diseases.
Harvesting Tomatoes:
- Harvest tomatoes when they are fully colored and firm. Frequent harvesting during Oklahoma’s peak summer months helps ensure the best quality fruit and prevents overripening.
