This edamame soybean packs a lot of flavor and production into 2' compact plants. Dark green pods hold their color well and the large beans have exceptional soybean flavor when eaten fresh: “soft, sweet, nutty, almost milk-like, yum” was how our trial eaters described it. Picking can be staggered over a short 10-day harvest window as they ripen from the bottom of the plant to the top. They are widely adapted and have a high percentage of 3-seeded pods under optimal conditions. Great for small gardens.

Additional Information

Soybeans

  • Average 80-100 seeds/oz.
  • Days to maturity are from seeding date.

Culture: Edamame are day-length sensitive. Sow around the same time as sweet corn and harvest when most of the pods have expanded but are still green without yellowing.

Very sensitive to cold—be sure frost danger has passed, and soil temps have reached 65–80° before seeding. Plant 3–4" apart. Can tolerate dry soil prior to blooming, but needs water during the pod-filling stage. For fresh eating, harvest when most of the pods have expanded but are still green without yellowing. For best flavor harvest in the evening.

The Japanese call them edamame, meaning ‘beans on branches,’ and boil and salt them like beer nuts. Edamame are rich in vitamins A, C and E, calcium, phosphorus, protein and dietary fiber. Encouraged by its recent popularity surge, breeders are selecting for larger pods with sweeter beans.

Steam or boil the pods for 4–5 minutes, chill quickly for easy shelling. Pods can be parboiled and frozen. Staffer Emily wasn’t much interested in edamame until she froze a few quarts for winter. “Wow, they are rich, flavorful and taste so vibrant and alive!” Fresh-market growers often cut off plants near the base, remove the leaves and bunch into 1 lb units, rather than pick each pod individually.

Good companions: Seedsman Tom Vigue plants edamame in the same furrow as his sweet corn. He thins each to one plant per row foot and suffers little yield loss from either crop: the soybeans are a gift. He sows a living mulch of forage radish that takes off after both main crops are dead. He follows the next year with potatoes which benefit in rotation from all three of these crops.

Saving Seed: Soybean seed is easy to save! To save seed, leave some pods on the plants and wait till stems dry and most of the leaves drop. Expect about 1 lb per 10 row feet.

Pests: Young plants 2nd only to brassica seedlings as woodchucks’ preferred gourmet treat. Japanese beetles also love them but can be controlled by assiduous hand-picking.

Beans

  • All beans are open-pollinated.
  • Days to maturity are from seeding date.

Culture: Tender, will not survive frost. Inoculate with a legume inoculant, then plant seeds 3–4" apart in rows 24–30" apart after all danger of frost has passed and soil has warmed. Minimum germination soil temperature 60°; optimal range 70–80°. White-seeded beans are generally more sensitive to cold soil temps than dark-seeded varieties. Legumes have moderate fertility needs and can fix their own nitrogen.

Saving Seed: Saving bean seed is easy! Leave pods on the plants to dry. Hand shell, or stomp pods on a tarp. To ensure true-to-type seed, separate varieties by 30 feet.

Diseases:

  • ANTH: Anthracnose
  • BBS: Bacterial Brown Spot
  • CBMV: Common Bean Mosaic Virus
  • CTV: Curly Top Virus
  • DM: Downy Mildew
  • HB: Halo Blight
  • NY 15: NY 15 Mosaic Virus
  • PM: Powdery Mildew
  • PMV: Pod Mottle Virus
  • R: Rust
  • SC: Sclerotina

White mold, Sclerotinia sclerotiorum, affects more than 300 plant species. In beans, low humidity, good air circulation and wider spacing, both between plants and between rows, reduce the likelihood of this soil-borne infection.
