When to Seed Edamame

Edamame is a fast-maturing, frost sensitive crop that should be directly seeded into the garden after all danger of frost has passed. 

Where to Plant Edamame

Edamame will want a spot with full sun and loose, well-draining soil. They’ll love a spot rich in organic matter, but too much nitrogen can cause plants to produce more leaves than flowers or pods. 

Growing Edamame

Plant edamame one inch deep and one to three inches apart, in rows one to two feet apart. Once germinated, they can be thinned to their mature planting distance of three to four inches. Assuming your soil is high quality with well-aged organic matter, you shouldn’t have to apply any kind of fertilizer. Something that can be helpful is to use a legume inoculant. This ensures that legumes will have all of the symbiotic microbes they need. Typically, these microbes are already found in the soil but can be in low numbers if your garden is depleted or has recently been converted from a lawn. Make sure they get at least one inch of water per week.

Harvesting Edamame

Edamame are known for maturing all at once (within a few weeks of each other), rather than pole beans that produce continuously. Plant edamame in successions every two weeks for a continuous harvest. Pick edamame once the seeds inside the pods have matured and are plump.

Pollination, self; Life Cycle, annual; Isolation Distance, 20 feet

As with most beans, cross-pollination is rare, but to ensure variety purity, separate different types by at least 20 feet. Soybean anthers shed pollen before the flowers open, this means that pollination and fertilization are completed before the flower opens. Save seed from healthy, disease free plants when the seed pods are completely dry (the beans will rattle in the pods). Winnow beans from pods/chaff. The hardest and heaviest seeds will be best for replanting, eat the rest.
