Seedling
3-4 weeksSmall plants with first true leaves emerging; 2-4 weeks old with 2-4 leaves visible
Maintain warm soil (70-80°F), provide bright light, and keep soil consistently moist. Begin light feeding at 3-4 weeks with diluted fertilizer.
Vegetative Growth
4-6 weeks after transplantingPlants develop multiple stems and leaves, growing 6-12 inches tall; no flowers yet
Maintain warm temperatures (75-85°F), provide full sun, feed with balanced fertilizer every 2 weeks. Pinch main stem when 8 inches tall to encourage branching.
Flowering
3-4 weeksSmall white flowers appear at leaf axils; plants typically 12-18 inches tall with dense foliage
Maintain consistent watering and temperatures above 70°F (below 60°F causes flower drop). Switch to phosphorus-rich fertilizer to promote flowering. Kaimana is heat-tolerant and sets flowers well in hot conditions.
Fruit Development
3-4 weeksYoung green peppers form behind flowers, growing rapidly; plants reach full height of 24-30 inches
Continue consistent watering and feeding; switch back to balanced fertilizer. Support heavy fruit with stakes if needed. Thin excessive fruit early for larger peppers. Watch for heat stress in extreme temperatures.
Maturation & Harvest
Continuous harvest for 2-3 months or longerPeppers enlarge to full size (3-4 inches), thicken walls, and transition from green to red if left on plant
Begin harvesting at mature green stage or wait for red color. Continue regular watering and feeding to support extended production. Kaimana produces abundant fruit over long season.

Harvest Tips
Pick peppers at mature green stage (75-80 days) for immediate use, or leave on plant 15-20 additional days to turn red for sweeter flavor and higher vitamin C. Cut with pruners rather than pulling to avoid branch damage. Kaimana produces prolifically; harvest every 2-3 days during peak season to encourage continued production. Fruits are thicker-walled and store longer than standard bell peppers.
Fun Facts
