Fruiting
6-8 weeksGreen peppers begin developing behind faded flowers, growing upright. Plant becomes heavier with fruit weight. Peppers gradually enlarge and transition from green to bright red.
Maintain consistent watering and avoid fluctuations. Provide support stakes for heavy fruit loads. Switch to higher potassium fertilizer. Thin some fruits for larger individual peppers if desired.

Harvest Tips
Harvest when peppers reach full red color for maximum sweetness and heat level (around 75-90 days). Pick peppers with sharp scissors or pruners to avoid damaging branches. Can be harvested green if desired, though red peppers are sweeter. Regular harvesting encourages continued fruit production. In cooler climates, harvest remaining peppers before frost and bring indoors to ripen on windowsill.
Fun Facts
- 🌱 Hong Kong Red peppers are technically berries, not vegetables, as they develop from the flower's ovary and contain seeds.
- 🌱 The upright-pointing fruit orientation is called 'erect pod habit' and makes harvesting and viewing the beautiful peppers easier than drooping varieties.
- 🌱 These peppers contain capsaicin, the same compound that creates heat in jalapeños and habaneros, but in moderate amounts that make them pleasantly hot rather than intensely spicy.
