- Fiber: Fiber crops are planted at a rate of approximately 40-80 lbs per acre. This could be higher if germination is low or seeds are large. High-density plantings promote vertical growth, producing long, higher quality primary bast fibers, as opposed to core hurd fibers. Large quantities of hemp seeds must be planted to establish optimal crop density and to suppress weeds. However, it is important to recognize that difficulties may also result from plant competition. Final stand density should be approximately 30-35 plants per square foot for fiber.
- Harvest typically occurs when 10-20% of plants are flowering (will observe pollen release), typically 60- 70 DAP. See processing tab for more harvest details.
- Fiber processing companies should provide guides on production, harvest timing, and harvest method.
