Seedling
3-4 weeksTiny plants with 2-3 true leaves emerge 7-10 days after germination. Cotyledons (seed leaves) appear first, followed by true leaves with characteristic tomato shape.
Maintain warm soil (70-75°F), provide bright light 14-16 hours daily, keep soil moist. Use grow lights if windowsill light is insufficient.
Vegetative Growth
2-3 weeksPlant develops 4-6 true leaves and establishes a compact, bushy form. Roots become established in containers or soil. Plant grows 4-6 inches tall.
Harden off transplants by gradually exposing to outdoor conditions over 7-10 days. Plant outdoors after last frost when soil reaches 60°F. Water consistently and avoid waterlogging.
Flowering
2-3 weeksYellow flowers appear in clusters (often 3-5 flowers per truss) at leaf axils. Plant reaches 10-14 inches tall and becomes increasingly bushy.
Maintain consistent watering and fertilization with balanced or slightly higher phosphorus fertilizer. Ensure 6+ hours of direct sun daily. Light pruning of lower leaves improves air circulation.
Fruiting & Ripening
4-6 weeksSmall green tomatoes (marble-sized) develop at flower clusters. Tomatoes gradually enlarge to 1-1.5 inches and change from green to red over 20-30 days.
Continue regular watering and feeding with tomato fertilizer (higher potassium). Support branches with fruit if needed using small stakes or cages. Prune sparingly to avoid exposing fruit to sunscald.
Harvest & Continued Production
Until frostRipe red tomatoes are ready to pick; plant continues producing new flower clusters and fruit throughout the growing season in warm conditions.
Harvest fully red tomatoes by gently twisting and pulling. Continue regular watering and feeding to encourage continuous production. Remove diseased leaves promptly.
