When to Start Growing Tomatoes from Seed

• Start seeds indoors 6-8 weeks before the last expected frost date in your area.
• This ensures your plants are strong and ready for transplanting when the weather warms up.

Choosing the Right Tomato Seeds

Consider the following types based on your preferences:

1. Cherry Tomatoes: Sweet and easy to grow (e.g., ‘Sungold,’ ‘Tumbling Tom’).
2. Beefsteak Tomatoes: Large and perfect for slicing (e.g., ‘Brandywine,’ ‘Cherokee Purple’).

4. Heirloom Varieties: Unique colors and flavors (e.g., ‘Black Krim,’ ‘Green Zebra’).

How to Grow Tomatoes from Seed Step by Step

1. Sowing the Seeds

1. Choose Containers: Use seed trays, pots, or cell packs with drainage holes.
2. Prepare Soil: Fill containers with a light seed-starting mix.
3. Plant Seeds: Sow seeds 1cm deep and cover lightly with soil.
4. Water Gently: Keep the soil moist but not waterlogged.
5. Cover: Use a humidity dome or plastic wrap to retain moisture until seeds germinate.

2. Caring for Seedlings

1. Provide Light: Place seedlings in a sunny window or under grow lights for 12-16 hours daily.
2. Keep Warm: Maintain a temperature of 18-24°C (65-75°F) for optimal growth.
3. Thin Seedlings: Once seedlings have two sets of true leaves, thin weaker plants by snipping them at the base.
4. Water Sparingly: Water when the soil feels dry to the touch, avoiding overwatering.

3. Transplanting Seedlings

1. Harden Off: Gradually expose seedlings to outdoor conditions over 7-10 days.
2. Prepare Soil: Enrich garden soil with compost or well-rotted manure.
3. Plant Deep: Bury seedlings deeper than they were in their pots to encourage strong root growth.

Tips for Growing Healthy Tomato Plants

1. Sunlight: Ensure plants receive 6-8 hours of direct sunlight daily.
2. Support Growth: Use stakes, cages, or trellises for indeterminate varieties.
3. Feed Regularly: Use a balanced fertilizer during early growth, switching to a tomato-specific fertilizer when flowering begins.
4. Water Consistently: Avoid letting the soil dry out or become waterlogged.
5. Prune Wisely: Remove suckers and lower leaves to improve airflow and focus energy on fruit production.

Common Problems and Solutions

1. Leggy Seedlings:
   • Provide more light or lower grow lights to prevent weak, spindly growth.
2. Damping Off:
   • Avoid overwatering and ensure proper air circulation to prevent fungal diseases.
3. Yellow Leaves:
   • Check for overwatering, nutrient deficiencies, or insufficient light.
4. Pests:
   • Inspect plants regularly and use organic solutions to manage aphids, whiteflies, and other pests.

Harvesting Tomatoes

1. When to Harvest: Pick tomatoes when they are fully ripe and brightly colored.
2. How to Harvest: Twist gently or cut tomatoes from the vine to avoid damaging the plant.
3. Ripening Green Tomatoes: Place unripe tomatoes in a sunny spot or a paper bag with a banana to encourage ripening.
