Through various steps, let’s discuss how to grow edamame from the store-bought below.

But if you’re going to make soymilk, then choose yellow variety frosted edamame.

2. Choose The Right Soil

Choosing the right soil is quite essential for the growth of edamame. Good soil has various benefits, like less erosion and weeds. There is even a proper balance of nutrients in the soil, which helps the plant’s proper growth.

The best soil for edamame is drained correctly loamy soil. Well, medium-fertility soil can also be suitable for plant growth. But if you have high clay content, you can mix peat moss or sand on it.

3. Sow Seeds At The Right Time

The edamame will give higher production when planted in May. You also need to consider soil temperature while sowing seeds.

So, the best time for sowing seeds is two weeks after the last frost. During that time, the soil temperature will be 70 degrees Fahrenheit, and the air temperature will be 60 degrees Fahrenheit.

4. Prepare Seed Bed

Preparing a seed bed is quite important. The plant will not grow well if the soil has too much or too few nutrients. So, if your soil has poor nutrients, add compost or manure before adding seeds.

5. Inoculation

Edamame needs a lot of nitrogen for proper growth. One of the best ways to provide nitrogen to the plant is by inoculating the edamame seeds with Bradyrhizobium japonicum. You can purchase this bacterium from online stores or gardening stores nearby.

Put some beans in the bucket and sprinkle the Bradyrhizobium japonicum. Take the help of a spade so that every bean should be well coated with the bacterium.

Remove the beans from direct sunlight after coating and sow them within 24 hours of inoculation.

6. Time To Sow The Seeds

Sow the soybean seeds at least 1.5 inches deep into the soil. There must be 3 inches distance from one bean to another. You need to water the soil just after sowing the beans. But don’t overwater the soil, as it can crack the beans.

7. Keep The Animals Away From the Shoots

Animals like rabbits love edamame shoots and can damage them. So, it’s best to put a fence over the area where you are growing the plant.

8. Remove Weaker Plants

The soy plants will start to sprout within two weeks. If you observe any weak plants, uprooting is the best so that the strong soy plant will develop effectively.

12. Blanch The Pods
