Cultivation: Prepare fertile, well-drained soil in a warm, sunny location. Seeds can be difficult to germinate. For better germination, pre-sprout seeds indoors by soaking in water for 24 hours until swollen and then keep at 77ºF until sprouted. Scarify seed coat for seeds not swollen and resoak. Plant when seeds sprout. Keep soil moist. Fertilize sparingly. Train to grow on a vertical support. Large vigorous vines can reach 9-12'. Harvest beans up to 3" in length.
