1. Start Seeds Indoors

Plant seeds indoors 6-8 weeks before the last frost date.
Use seed trays and a quality seed-starting mix.
Keep the soil moist and warm (70-75°F) for germination.

2. Transplanting Seedlings

Harden off seedlings by gradually introducing them to outdoor conditions.
Transplant into the garden or containers when nighttime temperatures stay above 50°F (10°C).
Space plants 2-3 feet apart to allow for proper airflow.

3. Soil Preparation

Use well-draining, nutrient-rich soil with a pH of 6.0-6.8.
Mix compost or organic matter into the soil to improve fertility.

4. Watering and Mulching

Water consistently to keep the soil evenly moist but not waterlogged.
Apply mulch to retain moisture and regulate soil temperature.

5. Provide Support

Use stakes, cages, or trellises to support the heavy fruit-laden plants.
Tie the vines loosely to prevent breakage.

6. Fertilizing

Use a balanced fertilizer or one formulated for tomatoes.
Avoid excessive nitrogen, which promotes foliage growth over fruit production.

7. Sunlight for Color Development

Ensure plants receive full sun (6-8 hours daily) to enhance the blue pigmentation.
Anthocyanins develop more intensely with direct sunlight exposure.

Pick blue tomatoes when they reach their full color and are slightly soft to the touch.
Allow some varieties to ripen further for the best flavor.
