Growing Edamame in Zone 9B

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

Zone 9B has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

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)

Harvest Timeline

75-90 days; harvest when pods are plump and bright green
