FoxFibre Rust
Gossypium hirsutum var. FoxFibre
vegetableFoxFibre Rust is a naturally colored, organically grown cotton variety developed through selective breeding to produce fiber with inherent rust-brown coloration, eliminating the need for synthetic dyes. This heirloom cotton was developed by Sally Fox in California and represents a breakthrough in sustainable textile production. The plant produces bolls containing this distinctive colored fiber that can be spun and woven directly without chemical processing.

Seedling
2-3 weeksCotyledons emerge within 5-10 days; true leaves develop shortly after
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing early. Protect from cold temperatures below 60°F.
Vegetative
6-8 weeksPlant develops multiple branches and grows 3-5 feet tall; dark green compound leaves appear
Maintain consistent watering and apply balanced fertilizer every 4-6 weeks. Mulch to conserve moisture and regulate soil temperature. Pinch off excessive branching if desired.
Flowering
4-6 weeksCream or pale yellow flowers bloom in the leaf axils; flowers wilt and drop within 1-2 days
Reduce nitrogen fertilizer to encourage flowering over excessive vegetative growth. Maintain steady water supply but avoid overwatering. Monitor for pests actively during this stage.
Boll Development
6-8 weeksSmall green bolls form where flowers dropped; bolls enlarge and harden over time
Gradually reduce watering frequency to concentrate fibers and develop color depth. Avoid excess nitrogen which can delay maturity. Watch for boll weevils and other pests.
Harvest
Ongoing from 150 days onwardBolls split open naturally, revealing fluffy rust-colored fiber; lint dries to a characteristic brown hue
Pick bolls when fully open and dry. Handle gently to avoid fiber loss. Separate fiber from seeds by hand-ginning or using a simple cotton gin. Air-dry thoroughly before storage.

Common Pests
-
Hand-pick infested bolls early in season; plant trap crops; use pheromone traps; remove plant debris immediately after harvest; rotate crops annually
-
Spray with neem oil or insecticidal soap; increase humidity with overhead irrigation; encourage natural predators; avoid excessive nitrogen fertilizer
-
Strong water spray to dislodge; insecticidal soap; neem oil; encourage beneficial insects like ladybugs and lacewings
-
Pheromone traps for monitoring; remove and destroy infected bolls; clean up plant debris; practice crop rotation
-
Improve air circulation with proper spacing; avoid overhead watering; remove infected leaves; use copper fungicide if severe; rotate crops
Uses
Natural Fiber for Textiles
CraftFoxFibre Rust produces fiber that can be spun into yarn and woven into fabric without synthetic dyes, creating naturally rust-brown colored textiles. The fiber is suitable for handspinning, machine spinning, and weaving into clothing, blankets, and other textiles. [source]
Sustainable Textile Production
HouseholdUnlike conventional white cotton that requires extensive chemical dyeing, FoxFibre Rust eliminates environmental pollution and water waste associated with industrial dyeing processes. This makes it ideal for eco-conscious textile producers and consumers. [source]
Cottonseed Oil and Meal
CulinaryWhile primarily grown for fiber, cotton seeds can be processed to produce cottonseed oil for cooking and cottonseed meal for livestock feed, providing additional value from the plant. [source]
Heritage and Heirloom Preservation
CraftGrowing FoxFibre Rust supports agricultural biodiversity and preserves an important heirloom cotton variety developed through sustainable breeding practices. Home gardeners can save seeds and participate in seed-keeping traditions. [source]
Pollinator Support
WildlifeCotton flowers attract and provide nectar for native bees, butterflies, and other pollinators, making cotton gardens beneficial for local ecosystems and pollinator populations. [source]
Harvest Tips
Cotton is ready to harvest when bolls split open naturally and fiber is fluffy and dry (approximately 150-180 days after planting). Pick bolls by hand in the morning after dew dries. Wear gloves as the sharp boll edges can cut skin. Bolls will continue to open over several weeks—harvest every 3-4 days for optimal fiber quality. For hand-ginning, separate the lint from seeds using a simple roller gin or by hand (labor-intensive but traditional). Store dried fiber in a cool, dry place.
Fun Facts
- 🌱 FoxFibre Rust was developed by Sally Fox in the 1980s through selective breeding and represents decades of work to create naturally colored cotton without genetic modification, proving that traditional plant breeding can achieve remarkable results.
- 🌱 The rust-brown color comes from natural pigments in the fiber itself and deepens slightly with age and exposure to sunlight, much like natural indigo-dyed fabrics, creating unique vintage effects over time.
- 🌱 A single mature cotton plant can produce 1-2 pounds of raw cotton, which yields approximately 0.5 pounds of processed lint—enough to make a single t-shirt or several scarves depending on weaving density.
