Seedling
2-3 weeksTiny seedlings with 2 cotyledons (seed leaves) emerging, followed by true leaves with characteristic pepper leaf shape
Provide warm conditions (70-75°F), consistent moisture, and bright light. Thin to strongest seedlings. Begin fertilizing with dilute liquid fertilizer at true leaf stage.
Vegetative Growth
4-6 weeksPlant develops multiple branches and dark green foliage; gradually becomes bushier and more compact
Maintain warm temperatures (65-80°F), full sun exposure, and regular watering. Fertilize every 2 weeks with balanced fertilizer. Harden off before transplanting outdoors.
Flowering
3-4 weeksSmall white flowers appear in leaf axils; flowers are delicate with 5-6 petals and yellow anthers
Maintain consistent moisture and warmth (70-80°F). Avoid excessive nitrogen fertilizer, which promotes foliage over flowers. Ensure good air circulation to aid pollination.
Fruit Development
2-3 weeksSmall green peppers form after successful pollination; gradually enlarge to blocky, medium-sized shape
Continue consistent watering and provide support stakes if needed. Switch to fertilizer with higher phosphorus/potassium ratio. Ensure full sun for color development.
Maturation & Harvest
1-2 weeks per fruitPeppers transition from green to glossy bright red; walls thicken and pepper sweetens as it matures
Maintain steady watering and warmth. Harvest green peppers anytime for earlier production, or leave on plant 7-10 days longer for full red color and peak sweetness. Support heavy fruit branches.

Harvest Tips
Fireking peppers can be harvested green (after about 60-65 days) for a crisp, slightly grassy flavor, or left on the plant for 7-10 additional days to turn red and develop sweetness. Cut peppers with pruning shears or scissors rather than pulling to avoid damaging branches. Harvest regularly to encourage continued fruiting. Each plant typically produces 20-30+ peppers over the season.
Fun Facts
- 🌱 Fireking peppers are considered 'early maturity' varieties, bred specifically for short-season growing regions and northern climates, making them one of the fastest bell pepper cultivars to produce fruit.
- 🌱 Bell peppers are technically berries—the entire pepper is the fruit of the plant, developing from the flower's ovary.
- 🌱 Red peppers contain up to 3 times more vitamin C than green peppers because the fruit continues to synthesize ascorbic acid as it matures and changes color.
