Extra-long Staple Cotton

Sowing: Seeds can be started indoors in trays or sown directly once the soil has warmed, then set out or thinned to stand 12 to 24 inches apart in a site that receives six to eight hours of direct sun and some shelter from strong wind.

Watering: The plant wants a fertile, well-draining sandy loam and steady deep watering through its growth and boll-forming stages, since soggy ground invites root rot while drought cuts yield; a balanced fertilizer, with extra phosphate and potassium worked in ahead of boll set, supports fiber development.

Pruning: Removing lower branches early in the season and cutting out damaged or overcrowded growth improves air movement through the canopy and keeps the bush a manageable size.

Pests: Growers watch for aphids, whiteflies, and bollworms on the foliage and developing bolls, treating outbreaks with insecticidal soaps or other organic insecticides.

Disease: Powdery mildew and other fungal infections can take hold, especially where airflow is poor, and are addressed with fungicides; rotating the crop between seasons helps limit disease buildup, while waterlogged soil is a separate route to root rot.

Bolls typically mature roughly 160 to 180 days after sowing and are hand-picked once they have turned brown and split open. The fiber is then worked free of the seed by hand or run through a cotton gin.

Textile: This crop is grown for its exceptionally long, fine, silky fiber, prized for spinning into fine, luxury-grade cotton thread and cloth; fabric sold under the Egyptian cotton name is historically traced to this same plant stock carried over from the Americas rather than to a separate local crop.

Ornamental: Its showy yellow flowers, often marked with red or purple at the base of the petals, make it a garden and conservatory subject in its own right.

Medicinal: In folk and indigenous medicine the leaves have traditionally been brewed as a tea, a use recorded in traditional healing practice rather than an established treatment.

The species traces to wild cotton of the arid coastal country spanning southwestern Ecuador and northwestern Peru, within a broader native range reaching from Colombia to Peru, where it was brought into cultivation by peoples of the region in antiquity. Following European contact it was carried into the Old World tropics and subtropics, and further selection during the 19th century produced the long-fibered forms that made the species especially valued for textile use.
