Seedling
2-3 weeksYoung plants with 2-3 true leaves, delicate and pale green
Keep soil consistently moist but not waterlogged. Provide bright light (14-16 hours). Maintain 65-75°F. Thin or transplant to prevent crowding.
Vegetative Growth
4-6 weeksRobust bushy plant with multiple stems, dark green foliage, reaching 3-4 feet tall
Support with stakes or cages early. Pinch suckers for determinate types if desired. Fertilize every 2-3 weeks with balanced fertilizer. Maintain consistent watering.
Flowering
3-4 weeksYellow flowers appear in clusters (trusses) along stems; plant may reach full height
Continue staking/caging. Maintain even soil moisture to prevent blossom-end rot. Reduce nitrogen; switch to phosphorus-rich fertilizer. Pollinate by hand or encourage pollinators.
Fruit Development
3-4 weeksSmall green fruits form and gradually enlarge; begin to show golden-orange color
Water consistently; irregular watering causes cracking and disorders. Prune lower leaves as fruits ripen for air circulation. Continue balanced feeding.
Ripening & Harvest
2-3 weeksFruits fully orange-golden, soft to touch, fully developed flavor
Pick fruits when fully colored. Ripe tomatoes stop ripening on the vine once mature. Handle gently. Store at room temperature; do not refrigerate if possible.

Harvest Tips
Harvest when fruits are fully orange-golden, typically 68-80 days after transplant. Harvest in early morning for best flavor. Tomatoes can be picked slightly underripe and ripened indoors. Cut or gently twist off the vine. For end-of-season, pick mature green tomatoes and ripen on a windowsill.
