Seedling
2-3 weeksSmall plants with cotyledons (seed leaves) followed by first true leaves appearing
Maintain consistent moisture and 70-75°F temperature. Provide grow lights 14-16 hours daily if indoors. Keep soil moist but not waterlogged.
Vegetative Growth
3-4 weeks after transplantingPlant develops multiple leaf sets, becomes bushier, and establishes strong root system. Determinate growth pattern becomes evident as plant grows more compact.
Harden off seedlings before transplanting. Plant outdoors after last frost. Support with stakes or cages early. Pinch side shoots moderately to maintain compact form.
Flowering
2-3 weeksSmall yellow flowers appear in clusters (racemes) along the plant. Flowers develop on compact branching structure.
Maintain consistent watering to prevent blossom end rot. Avoid excess nitrogen which delays fruiting. Ensure adequate pollination through air movement or gentle shaking.
Fruiting & Development
3-4 weeksGreen fruits develop from flowers and enlarge over time. Fruits gradually change from green to breaker stage (first blush of color).
Support heavy fruit clusters with ties or additional caging. Maintain even watering. Remove lower leaves for air circulation but keep fruit shaded from intense sun in hot climates.
Ripening & Harvest
2-3 weeksFruits turn from breaker stage to full red color. Concentrated ripening due to determinate growth habit allows bulk harvest window.
Harvest at full red color for best flavor. Can pick at breaker stage and ripen indoors. Reduce watering slightly to concentrate sugars. Handle fruit gently.

Harvest Tips
Pick fruits at full red color for maximum flavor and sugar content. The determinate growth habit produces a concentrated harvest window, making this variety excellent for canning and processing. Twist gently or cut with scissors rather than pulling. Store at room temperature; refrigeration diminishes flavor. Green fruits can ripen indoors if picked at breaker stage.
