Edamame is just fresh-harvested soybeans — and home-grown edamame is incomparably sweet compared to store-bought. A fun summer crop.

Top Growing Tips

  • Wait until soil is 60°F+ to direct sow — seeds rot in cold soil
  • Inoculate seeds with soybean rhizobia for better nitrogen fixation
  • Harvest when pods are plump, bright green, and beans fill the pods
  • Boil pods in salted water for 5-7 minutes for classic preparation
  • All pods on a plant ripen around the same time — harvest entire plant at once

Companion Planting

Good companions: corn, cucumbers, summer squash

Avoid planting near: onions, garlic (inhibit growth)
