Growing Non-GMO Sea Island Brown Cotton Seeds

Sea Island Brown Cotton thrives in warm climates and well-draining, sandy loam soil rich in organic matter. Begin by amending the soil with compost or aged manure to enhance fertility and drainage. A slightly acidic to neutral soil pH of 6.0-7.0 is ideal. Choose a sunny location that receives at least 6-8 hours of direct sunlight daily. Sow the seeds directly into the garden after the last frost when the soil temperature consistently stays above 65 F. Plant seeds 1/2 inch deep and space them 12-18 inches apart in rows that are 36-42 inches apart.

If starting seeds indoors, plant them 4-6 weeks before the last frost. Transplant seedlings outdoors once they have developed two sets of true leaves and nighttime temperatures remain above 60 F. Harden off seedlings by gradually exposing them to outdoor conditions over a week before transplanting.

Fertilize plants with a balanced fertilizer (such as 10-10-10) when seedlings are a few inches tall and again at the first bloom. Avoid excessive nitrogen, as it can promote foliage growth at the expense of fiber production. Keep the planting area weed-free, especially in the early stages of growth, to minimize competition for nutrients. Mulch around the base of the plants to suppress weeds and retain soil moisture. Although cotton plants generally do not require structural support, a few stakes can help stabilize taller plants in windy areas.

Pruning or pinching is not typically necessary, but removing damaged or diseased leaves can improve airflow and reduce the risk of fungal infections. Cotton benefits from companion planting with herbs like basil or marigold, which can deter pests like aphids. Avoid planting cotton near other members of the mallow family, as they share susceptibility to certain pests and diseases. Rotate cotton with nitrogen-fixing crops such as beans or clover to replenish soil nutrients.

Harvesting Sea Island Brown Cotton

Sea Island Brown Cotton is ready to harvest about 135 days after planting, typically in late summer or early fall. The primary indicator of readiness is the drying and splitting of the cotton bolls, revealing the fluffy brown fibers inside. Wait for dry weather to begin harvesting, as wet cotton is prone to mold.

To harvest, gently pull the cotton fibers from the opened bolls, wearing gloves to protect your hands from the sharp edges of the boll. Collect the cotton in a breathable container like a basket or cloth bag to prevent moisture buildup. Once harvested, remove any seeds or debris from the fibers before storage or use.

About Sea Island Brown Cotton Garden Seeds

This cotton variety is known for its brown-colored fibers rather than the traditional white cotton. The brown fibers are naturally colored and are highly prized for making eco-friendly fabrics.

Sea Island Brown Cotton originates from the Sea Islands off the coasts of Georgia and South Carolina. It was a cornerstone of the region’s agricultural economy during the 18th and 19th centuries, cultivated by enslaved African laborers who brought advanced cotton-growing techniques from their homelands. The variety was particularly valued for its long, silky fibers and natural brown color.

The attractive brown cotton bolls add an ornamental value to gardens, making it a dual-purpose plant for fiber production and decorative use. It is popular for use in dried flower arrangements and other dried decor.

This variety may be referred to as Brown Cotton, Sea Island Cotton, or Brown Sea Island Cotton.

Tips From Our Gardeners

"While cotton requires consistent moisture early in its lifecycle, Sea Island Brown Cotton is relatively drought-tolerant once established. That’s why growers in regions with intermittent rainfall or water restrictions find this variety appealing."
