Growth Stages

1

Seedling

2-3 weeks

Emergence of cotyledons and first true leaves; plant is fragile and low to the ground

Keep soil consistently moist but not waterlogged; protect from damping-off disease; thin seedlings to proper spacing if direct seeding

2

Vegetative

6-8 weeks

Rapid stem and leaf growth; plant develops multiple branches and a robust canopy; no flowers yet

Maintain regular watering and consistent NPK nutrition; monitor for pests like spider mites and whiteflies; pinch off lower branches if desired to improve air circulation

3

Flowering

4-6 weeks

Flower buds (squares) form, followed by distinctive pale yellow or cream flowers that turn pink/red as they age before dropping

Continue consistent watering and feeding; watch for boll weevils and other pests; reduce nitrogen if growth is too vegetative

4

Boll Development

6-8 weeks

Small green bolls form where flowers fell; bolls swell and change color from green to reddish-brown as fibers develop inside

Reduce watering frequency to stress the plant slightly and improve fiber quality; continue pest monitoring; avoid excessive nitrogen which can delay maturity

5

Maturity & Harvest

3-4 weeks

Bolls dry, split open naturally, and fluffy white fibers are exposed; plant may begin to senesce

Stop watering; harvest bolls as they open; monitor weather for rain which can stain fibers; pick promptly to prevent dirt contamination

Common Pests

  • Inspect buds and bolls weekly; remove infested bolls; use pheromone traps; apply neem oil or insecticidal soap early in season; rotate crops annually

  • Spray with water to dislodge; use miticides if severe; encourage beneficial insects; maintain consistent irrigation to reduce plant stress

  • Use yellow sticky traps; spray neem oil or insecticidal soap; encourage natural predators; avoid broad-spectrum pesticides

  • Hand-pick larger larvae; use Bt (Bacillus thuringiensis) for young larvae; monitor with pheromone traps; remove weeds that harbor pests

  • and (fungal)

    Choose resistant varieties; ensure excellent drainage; rotate crops; sterilize tools; remove infected plants promptly

Harvest Tips

Suvin cotton bolls mature 20-25 days after flowering. Pick bolls as they naturally split open and fibers are fluffy white, typically 3-4 weeks after the flowering stage ends. Wear gloves as opened bolls have sharp leaf edges. Harvest before rain to prevent fiber staining and contamination. Hand-pick for premium quality; avoid mechanical harvesting which can damage the prized long staple fibers. Remove all lint from seed for optimal quality textiles.
