Updated: June 22, 2022

Edamame is a popular snack that is not only tasty but also nutritious. Edamame plants are easy to grow, and you can harvest your own edamame pods right in your garden. Edamame seeds are available both online and at local stores. If you’re looking to grow your own edamame plants, it’s important to know how to store, sow and germinate the seeds.

Storing Edamame Seeds

Edamame seeds should be stored in a cool, dry place to ensure their viability. Seeds stored at room temperature or exposed to moisture will lose their ability to germinate. The ideal storage temperature is between 32-41°F (0-5°C) with low humidity. The refrigerator is a good place to store edamame seeds if you don’t have a cool, dry basement or root cellar.

Sowing Edamame Seeds

Edamame seeds should be sown directly into the soil after the last frost date in spring. You can start them indoors about 4-6 weeks before the last frost, but they do not transplant well, so it’s best to sow them directly in the ground.

Choose a site with full sun exposure and well-draining soil. Plant the seeds 1 inch deep and 2-3 inches apart in rows spaced 2 feet apart. Water the soil thoroughly after planting.

Germinating Edamame Seeds

Edamame seeds will germinate within 7-14 days if the soil temperature is around 60-80°F (15-27°C). Keep the soil moist during germination but avoid overwatering as this can cause the seeds to rot.

Once the seedlings emerge, thin them out so that they are spaced about 4 inches apart. This will allow for optimal growth and airflow around the plants. Edamame plants grow up to 3 feet tall, so make sure you provide adequate support to keep them upright.


How long do edamame seeds last?

Edamame seeds can last up to 3 years if stored properly in a cool, dry place.

Can I sow edamame seeds in containers?

Yes, you can sow edamame seeds in containers as long as they are at least 12 inches deep and wide. Make sure the container has drainage holes and use a well-draining potting mix.

What pests should I watch out for when growing edamame plants?

Edamame plants are susceptible to aphids, Japanese beetles, and spider mites. You can control these pests by spraying the plants with neem oil or insecticidal soap.

When is the best time to harvest edamame pods?

Edamame pods should be harvested when they are plump and green but before they start to turn yellow or brown. This is usually about 80-90 days after planting.

Can I save edamame seeds for next year’s planting?

Yes, you can save edamame seeds for next year’s planting. Allow the pods to dry on the plant, then remove the seeds and store them in a cool, dry place until planting season.

In conclusion, growing edamame plants from seed is easy and rewarding. With proper storage, sowing and germination techniques, you can enjoy fresh and nutritious edamame pods right from your backyard.
