Asiatic Cotton
Gossypium arboreum
shrubAsiatic cotton is a perennial woody shrub native to India and Africa, prized for its long, fine cotton fibers used in textile production. It grows 1.5-2 meters tall and produces distinctive yellow flowers followed by bolls containing soft, white fibers. This species is known for its hardiness and adaptation to diverse climates compared to other cotton varieties.

Germination & Seedling
2-3 weeksSeeds sprout within 7-10 days, producing two cotyledons and small true leaves
Keep soil warm (75-85°F) and consistently moist but not waterlogged. Provide bright light. Thin seedlings to appropriate spacing.
Vegetative Growth
6-10 weeksPlant develops multiple branches, compound leaves, and establishes a sturdy woody stem structure
Maintain full sun exposure and moderate watering. Apply balanced fertilizer every 3-4 weeks. Prune lower branches if desired to encourage upright growth.
Flowering
6-12 weeksLarge, showy yellow flowers appear at branch axils, which turn pink or red as they age before dropping after one day
Reduce nitrogen fertilizer to encourage flowering over leafy growth. Continue consistent watering. Ensure good air circulation. Flowers attract pollinators.
Boll Development
4-6 weeksFlowers are replaced by developing cotton bolls (seed pods) that swell and increase in size
Maintain steady watering; drought stress can cause boll drop. Apply phosphorus and potassium-rich fertilizer. Monitor for pests. Keep foliage dry to prevent disease.
Boll Maturity & Harvest
2-4 weeks (harvest period)Bolls dry, harden, and burst open to reveal fluffy white (or rarely colored) cotton fibers inside
Once bolls open, begin hand-harvesting. Handle fibers gently to maintain quality. Continue harvesting over several weeks as more bolls mature.

Uses
Cottonseed oil extraction
CulinaryCotton seeds contain oil that can be extracted and used for cooking and food production. Cottonseed oil is a staple cooking oil in many cuisines. [source]
Textile fiber production
CraftThe primary use of Asiatic cotton is harvesting the soft white fibers from bolls for spinning into yarn and weaving into high-quality textiles, clothing, and bedding. Its fibers are finer and softer than many other cotton species. [source]
Natural batting and stuffing
HouseholdHarvested cotton fibers can be carded and used as natural, biodegradable batting for quilts, pillows, and other fabric projects without chemical processing. [source]
Traditional medicine uses
MedicinalIn traditional Ayurvedic and Chinese medicine, various parts of the cotton plant including roots, seeds, and oil have been used to address inflammation and digestive issues, though scientific evidence is limited. [source]
Pollinator attraction
WildlifeThe large, fragrant yellow flowers are highly attractive to bees, butterflies, and other pollinators, making Asiatic cotton plants valuable for supporting pollinator populations in gardens. [source]

Harvest Tips
Wait until bolls open naturally and fibers are fully exposed and fluffy. Harvest by hand, gently pulling fiber tufts from the open boll. Leave a small amount of fiber attached to the seed for easier separation later. Harvest in the morning when bolls are driest. Multiple harvests can occur over the growing season as additional bolls mature.
Fun Facts
- 🌱 Gossypium arboreum is one of the oldest cultivated cotton species, domesticated in India over 5,000 years ago and referenced in ancient Hindu texts.
- 🌱 Asiatic cotton flowers last only one day—they open in the morning yellow and turn pink or red by evening before falling off, a feature known as ephemeral flowers.
- 🌱 Unlike herbaceous cotton (Gossypium hirsutum), Asiatic cotton is a perennial woody shrub that can live for several years, producing multiple harvests per season in frost-free climates.
