Sowing Guidelines

Indoor/Greenhouse Sowing:

• Start seeds indoors 6-8 weeks before transplanting.
• Sow seeds ¼ inch deep in a quality seed-starting mix.
• Maintain soil temperature at 70-85°F (21-29°C) for best germination.
• Provide 12-16 hours of light daily using grow lights if needed.

Germination

• Seeds typically sprout within 7-14 days under optimal conditions.
• Keep soil evenly moist but avoid overwatering.

Transplanting

• When seedlings reach 6-8 inches tall and have at least two sets of true leaves, transplant them into larger containers or greenhouse beds.
• Harden off seedlings gradually by adjusting temperature and airflow for 5-7 days before final planting.

Spacing & Growing Conditions

• Indeterminate Varieties: 18-24 inches apart, with 3-4 feet between rows. Requires trellising or staking.
• Determinate Varieties: 12-18 inches apart, with 2-3 feet between rows. May need light support.

Care & Maintenance

• Watering: Keep soil evenly moist with deep watering 1-2 times per week. Use drip irrigation to prevent disease.
• Fertilization: Apply a balanced fertilizer every 3-4 weeks, adjusting for phosphorus and potassium during fruiting.
• Mulching: Use mulch to retain moisture, suppress weeds, and regulate soil temperature.
• Pruning: Remove suckers from indeterminate varieties to direct energy to fruit production.

Harvesting

• Harvest when tomatoes are fully ripened and deeply colored, typically 65-85 days after transplanting.
• Pick regularly to encourage continuous fruiting.

Pest & Disease Control

• Common Pests: Whiteflies, aphids, spider mites. Use neem oil or insecticidal soap if needed.
• Common Diseases: Powdery mildew, blight, and root rot. Maintain proper airflow, avoid overhead watering, and rotate crops annually.
