Growing directions
Sow seeds 1 to 1.5 in deep in rows 18–24 in apart; inoculate with soybean-specific rhizobium for best nitrogen fixation. Edamame is self-supporting but benefits from well-drained, fertile soil with only modest added nitrogen. Harvest when pods are bright green, plump, and the seeds fill the pod but the shell has not yet begun to yellow. To harvest, pull the entire plant and strip pods at once; blanch immediately for best flavor and color.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
