Seedling
3-4 weeksTiny plants with first true leaves appearing; fragile stems and minimal root system
Maintain consistent moisture and provide 14-16 hours of bright light daily under grow lights; keep temperature 70-75°F; avoid overwatering which causes damping off
Vegetative
4-6 weeksYoung plants with multiple sets of true leaves; developing strong root system and main stem; no flowers yet
Harden off seedlings gradually before transplanting; transplant into larger containers as needed; maintain warm temperatures 65-75°F; begin light fertilizing if growing in containers
Flowering
3-4 weeksPlant produces yellow flowers in clusters (trusses); flowers open and self-pollinate; tiny green fruit begin to form at flower bases
Ensure adequate pollination through gentle shaking or bee activity; maintain consistent watering and temperatures; apply calcium to prevent blossom end rot; support heavy stems with stakes or cages
Fruiting
4-6 weeksFruit develops rapidly, growing from marble-sized to full globe size; fruits transition from light green to mature red color; plant becomes heavy with foliage and fruit
Continue deep watering at soil level; prune lower leaves once fruit sets to improve air circulation; remove some upper leaves if shading ripening fruit; use sturdy supports; side-dress with compost
Harvest
6-10 weeksFruits reach full size and deep red color; firm texture and peak sweetness; plant continues producing new flowers and fruit until frost
Harvest fruits when fully colored and slightly soft; pick regularly to encourage continued production; handle fruits carefully to avoid bruising; in fall, harvest green fruit before frost and ripen indoors

Harvest Tips
Pick fruits when fully red and slightly yielding to gentle pressure for peak flavor and sweetness. Harvest regularly to encourage continued production. Fruits can be picked at the 'breaker stage' (first blush of color) and ripened indoors. In fall, harvest all fruit before first frost, including green tomatoes, and ripen them indoors in a cool location (68-72°F) away from direct sun.
