Seedling
2-3 weeksTiny plants with cotyledons and first true leaves emerging. Plant appears delicate with thin stems.
Keep soil consistently moist but not soggy. Provide 14-16 hours of grow light 2-3 inches above seedlings. Maintain temperature of 70-75°F.
Transplant/Vegetative
3-4 weeksYoung plants with 6-8 true leaves, developing stronger stems and root systems. Ready for outdoor planting after hardening off.
Gradually acclimate to outdoor conditions over 7-10 days. Harden off by exposing to wind and direct sun incrementally. Ensure adequate light to prevent leggy growth.
Growth & Flowering
3-4 weeksPlants rapidly increase in height and leaf production. First flower clusters appear on compact determinate plants (typically 24-36 inches tall).
Stake or cage plants early for support. Remove suckers minimally on determinate types. Apply consistent fertilizer every 2-3 weeks. Mulch to regulate moisture.
Fruiting
4-5 weeksSmall green fruits form at flower clusters. Fruits develop rapidly, changing color from green to red. Heavy fruit load is characteristic of this productive variety.
Maintain consistent watering to prevent blossom end rot and fruit cracking. Provide calcium supplementation if needed. Reduce nitrogen to avoid excessive leafy growth over fruiting.
Harvest
Ongoing, 2-3 weeks peak harvestFruits reach full red color and slight softness when gently squeezed. Peak flavor and sugar content are achieved at full ripeness.
Harvest ripe fruits regularly to encourage continued production. Pick fruits in the early morning for best quality. Can pick at breaker stage (first blush of color) and ripen indoors if frost threatens.
