Seedling
2-3 weeksTiny plants with 2-4 true leaves, pale green, fragile stems
Provide bright light 14-16 hours daily, keep soil moist but not soggy, maintain 65-75°F temperature, thin seedlings to prevent crowding
Vegetative Growth
3-4 weeksCompact bushy plants 4-12 inches tall with multiple stems and dark green foliage
Harden off gradually before transplanting outdoors, maintain consistent watering, apply balanced fertilizer every 2 weeks, pinch early flower buds to encourage plant establishment
Flowering
3-4 weeksSmall yellow flowers appearing in clusters on compact stems, plant reaches 12-18 inches
Ensure consistent watering and fertilizing, provide sturdy support (small stake or cage), switch to lower-nitrogen fertilizer to promote flowering, maintain warm temperatures (70-85°F)
Fruiting & Maturation
4-6 weeksGreen cherry tomatoes forming in clusters, gradually ripening to red/orange, plant fully leafed out
Continue consistent watering (critical to prevent blossom end rot and fruit cracking), apply mulch around base, fertilize every 2-3 weeks with tomato-specific formula, remove lower leaves as fruit matures for air circulation
Harvest
6-10 weeks until frostRipe red cherry tomatoes ready for picking, plant continues producing until frost
Pick tomatoes when fully colored but still slightly firm, harvest regularly to encourage continued production, continue watering and feeding for extended season

Harvest Tips
Begin harvesting when tomatoes are fully red/colored, typically 60-75 days after transplanting. Gently twist and pull ripe fruits or use pruning shears. Harvest regularly (every 2-3 days during peak season) to encourage continued production. Cherry tomatoes can be picked slightly before full ripeness and ripened indoors. The determinate nature means most fruit ripens within a concentrated window; stagger plantings every 2-3 weeks for continuous harvest. Plants typically produce until first frost.
