How to Grow Edamame

What is edamame?

Edamame is a Japanese word that translates to “beans on branches,” which describes how this soybean, which is a vegetable, develops. The pods grow in clumps on branches and bushy plants. Learn how to grow edamame ahead.

Contrary to livestock-type soybeans that are oily and tough and left to dry on the plant prior to harvest, edamame provides a tender, delicious bite that is harvested prior to the pods being fully ripe.

Edamame is a nutritious food that is also extremely satisfying. Because of its high nutritional value, it deserves to be considered a superfood. Edamame is high in protein, making it a good choice for vegetarians who don’t consume as much protein as meat-eaters.

Vitamin K and folate are rich in vegetable Edamame as compared to other vitamins and minerals. Edamame is high in protein, antioxidants, and fiber, which may help to decrease cholesterol levels in the blood.

 It’s unclear whether eating edamame lowers the likelihood of developing heart-related problems. Edamame is low in the glycemic index, making it an excellent choice for those with Type 2 diabetes.

 Edamame is a protein source of 18.4 grams which is an acceptable amount for a meal made of plants. There are different approaches to growing edamame as a plant which are discussed below:

Growing edamame in pots

Edamame beans taste delicious and are easy to grow in a vegetable garden that you can grow at home in the summer. Follow these steps to start your seeds of edamame beans:

Sow seeds in pots or on trays that are less than four centimeters (1 1/8″). Plant edamame in pots since it grows just 1-3 feet tall. It requires an area of 8-12 inches in depth and wide. 

In a pot that is large, it is possible to grow multiple plants as long as you maintain at least 6 inches between plants.

It’s a perennial plant that thrives in soil that is poor, however, it is important to supply sufficient water in order to maintain the soil damp.

Plant plants in the greenhouse. Or on a sunny windowsill.

It takes 7-14 weeks for the seeds to sprout.

If your plant is sporting some real leaves and has begun to appear overwhelmed in the module tray, pot them up.

We make use of a plastic pot for edamame cultivation because it’s cheap, sturdy, durable, and light. Make sure that the pot has drainage holes in the lower part. This allows it to drain the excess water and also protects the roots from developing root rot. If there is no hole you can make one before you use the pot.

Make use of the right potting soil that garden soil within your planter. The soil in your garden may contain excessive sandy or clay, or may not have the right texture to cultivate soybeans. The soil in the garden could contain insects, diseases, or chemicals that could affect the plant.

Transplanting soybeans

If you prefer, after the soil has warmed up, the seedlings should be spread outside in a bright and well-drained area.

Cloches or fleeces for protection from frost could be utilized to protect the seeds that were sown.

Grow edamame 12 to 18 inches from each other in a sun-drenched location that has soil that is well-drained and nutrient-rich.

Mix in a few inches of compost from the past or other organic materials to enhance the native soil. The edamame plant needs to be in moist soil until mature.

Once the soil is established, you should only water after the soil’s top inch is dry. Maintain your plants’ health by feeding them water-soluble plants on a regular schedule.

When the plants grow to 6 inches tall, then you can apply a layer of mulch made of finely powdered bark or leaves. The best time to harvest edamame is when the pods are green and plump.

Soil, planting, & caring

  • Summer is the most suitable time for planting Edamame, so you should wait to plant until the danger of frost has gone.
  • Plant seedlings only when the soil temperature is higher than 55 degrees F. Edamame plants tolerate various conditions, including drought light shade as well as clay-based soils.
  • Keep a soil that is slightly acidic. Edamame thrives best when it has acidic soil with a pH of 6.0. 
  • Place edamame plants 12-18 inches apart if there is enough space in your garden. The wider spacing lets more sunlight be able to reach every plant.
  • Cut down your plants. If your plants are approximately four inches remove the leaf matter until the plants are 6 inches apart. This can assist in preventing overcrowding.
  • Sow seeds with as little as 4 inches between. After edamame has matured, all pods on the plant mature simultaneously.
  • To harvest the season, utilize the method of succession planting to plant one or two edamame plants each week or so to ensure that the beans are fresh throughout all the time during growing.

How to grow edamame from seeds

Use these instructions to plant the seeds of edamame beans between mid-June and April.

  • Edamame seeds must be planted from one to two inches deep into your soil, spacing them three inches in a sunny area in your yard. The rows are separated by 2 feet. 
  • The trays should be watered lightly with a watering container with a fine rose.
  • Plant your seeds in a bright window or in the greenhouse.
  • Germination usually takes between 7 and 14 days.
  • The planting should be spread out. Seeds should be planted at least 10 days following the last plantation to ensure a continuous yield. Plant your plants after they’ve developed only a few leaves that are true and start looking like they are getting cramped in the module tray. Bright and sunny spots should be selected for the young plants
  • If you prefer, after the soil is warmed up you can sow the seeds directly outside in a bright and well-drained area. The seeds you have sown will be covered with blankets to guard against frost or Cloches.

How to harvest edamame Beans?

  • You’ll find an attractive green color in the beans. This is a sign that the edamame has been ripe to be harvested.
  • Check the pods for yellow spots. Streaks and yellow hues on the pods are a sign that the edamame pods are far beyond the ideal harvest.
  • Edamame has its best taste and nutritional quality at the time that pods reach 80–90% full.


  • Edamame beans harvest at various times, based on the level of sunshine they receive. The lighter your plants become, the sooner they will be ready to harvest.
  • The edamame harvest window is usually quite small, between three and seven days.
  • One can pick the pods at the point where they’ve gotten full and are pliable but remain vibrant green.
  • If pods become yellow, the flavor and nutritional value have surpassed their maximum and the beans will change to a taste and texture similar to lima beans.

Containers of seeds as well as a wicker basket and an expansion material are all included in the kit.

Edamame beans can be described as fully mature soybeans, which are sometimes called “vegetable-type soybeans.” They’re green and differ in hue from regular soybeans. They tend to appear lighter in color, like tan, or beige.

Growing edamame in the tropics

In the tropical regions, you can cultivate all year round, with the exception of summer. Plant edamame seeds after the summer season, when the temperature drops to 60 – 90 F (15 C – 32 C) Although soybean can tolerate temperatures of up to 100 F after being grown, it will decrease production during extreme temperatures.

How to grow organic edamame

Soil and water: the high clay soils can be amended using peat moss, sphagnum, or organic mulch in order to increase the amount of humus. 

Sand is a great option for the process of loosening or aerating the soil to facilitate drainage. Planting & Growing: Edamame requires healthy, fertile, and working soil that is well-drained and loose.

Though 94% of the total soybean production is grown using genetically modified varieties in the US, edamame is being processed in commercial quantities only by using genetically modified (GM) cultivars of edamame.

Edamame growing conditions

Few main conditions to be followed while growing Edamame:

  • Edamame is extremely easy to cultivate, particularly in warmer climates.
  • Edamame plants flourish best when the air and soil temperatures are between 60-70 degrees Fahrenheit without the risk of frost.
  • Place edamame plants 12-18 inches apart in a space with plenty of sunshine and nutrient-rich soil, well-drained.
  • Edamame is a frost-tolerant plant that is able to be planted in the last week of spring in a location where it receives all-day sunshine (at least 60 minutes) and has moderate soil fertility.
  • Make sure your plants are healthy by feeding them frequently with water-soluble plant seeds.
  • Spread a layer of mulch that is made of finely crushed bark or leaves once the plants are 6 inches in height.
  • Harvest edamame at the time that the pods are green and plump.

Challenges faced by edamame plants

Edamame production faces a variety of issues and challenges that include insufficient genetic resources, insufficient plant establishment and lodging poor structures of the plant, vulnerability seeds, and low yield potential, and more perishable in comparison to grain soybeans.

Companion plants of soybeans

Companion planting in agriculture and gardening is the plantation of various crops close to each other to serve a variety of reasons.

These include pollination, and pest control as well as providing habitat for beneficial insects, making the most efficient utilization of space, and increasing the productivity of crops.

Other plants that can be used as companions for edamame include cucumbers, corn strawberries, potatoes, as well as celery. Edamame is best cultivated away from plants belonging to that onion group, including onions and garlic. To take a bite or squeeze the pod’s bottom that will then pop out the bean.
