Growth Stages

1

Seedling

2-3 weeks

Tiny green leaves emerge from soil; plant is fragile with 2-4 true leaves present

Provide bright light under grow lights or on sunny windowsill; keep soil moist but not soggy; maintain 70-80°F for optimal germination

2

Vegetative

4-6 weeks

Plant develops multiple stems with dark purple-tinged foliage; compact bushy growth habit; no flowers yet

Pinch growing tips when 6-8 inches tall to encourage bushiness; maintain consistent moisture and warmth; fertilize every 2 weeks with balanced fertilizer; harden off before transplanting outdoors

3

Flowering

3-4 weeks

Small white to pale purple flowers appear at branch tips; flowers are self-pollinating

Ensure adequate sunlight and warmth (75-85°F); maintain consistent watering; apply low-nitrogen, higher-phosphorus fertilizer to encourage flowering; can hand-pollinate with small brush if indoor

4

Fruiting

4-6 weeks per fruit set

Peppers develop at flower sites; fruits are small and upright, initially dark purple, gradually transitioning to deep red

Continue regular watering and feeding; fruits will change color over 2-3 weeks; support heavy fruit with stakes if needed; harvest regularly to encourage more production

5

Harvest

Ongoing until frost

Fruits reach full size and desired color; peppers are firm and glossy

Pick peppers at any stage; can harvest at purple stage or wait for full red color for sweeter flavor; continue harvesting throughout season to promote new flower formation
