Planting Conditions in California
California’s diverse climate ranges from Mediterranean along the coast to arid in the interior, making it suitable for various planting strategies.
Sun Requirements
Tomatoes require full sun, with at least 6-8 hours of direct sunlight daily. In most regions of California, this requirement is easily met, especially with the state’s generally clear, sunny weather.
Starting Tomatoes Indoors
In regions like Los Angeles (Zone 10b), start tomato seeds indoors from February 1 to March 1. This gives plants a head start before transitioning them outdoors.

Transplanting Tomato Seedlings
Transplant seedlings outdoors from April 1 to April 30, once the risk of frost has passed and soil temperatures are consistently above 50°F. Space the seedlings about 24-36 inches apart in rows that are at least 36 inches apart, ensuring adequate airflow and sunlight penetration.
General Care and Maintenance
Watering:
- Regular watering is crucial to maintain evenly moist soil, particularly during the dry, hot summers.
- Deep, infrequent watering encourages a strong root system.
Fertilizing:
- Fertilize tomatoes at planting and again as fruits begin to form. Use a balanced, slow-release fertilizer tailored for tomatoes.
Pest and Disease Management:
- Monitor for common pests such as aphids, spider mites, and tomato hornworms.
- Employ cultural, mechanical, or biological controls to manage pest populations effectively.
Harvesting Tomatoes:
- Harvest tomatoes when they are firm and fully colored. In California’s warm climate, it’s often possible to let tomatoes ripen on the vine, although harvesting slightly early can help avoid issues with pests and splitting.
