This means that edamame beans are softer and sweeter than soybeans. Your edamame will do best in a spot in your garden that has well-draining soil and gets full sun. If possible, test your soil and pick a spot or amend it to provide your edamame with slightly acidic soil with lots of organic matter, such as compost , mixed in.
You will likely find that raised garden beds are easier to work with for this and other crops, particularly since it makes it easier to achieve the preferred soil quality and to control the conditions in which your plants are grown. You can grow green soybeans from seeds or purchase seedlings at your local garden center to transplant into your garden. Edamame is definitely a warm-weather plant, so if you live in an area that gets frost, you should start your seeds indoors and transplant them into your garden beds once the weather warms up.
If planting seeds in the soil, you can start by planting about four inches apart in rows that are about two feet apart. The right soil temperature is important to germination success. Lower temperatures can cause the seeds to struggle and possibly fail to germinate. Select a full-sun area with a nutritive, well-draining soil to plant your soybeans. Clay and other heavy soils may suffocate the seeds.
Improve your germination chances in clay or heavy soils by mixing in equal amounts of potting soil and sand with a gardening rake until it is blended evenly. Working in the additives will help aerate the bed and also distributes nutrients evenly.
Create planting rows spaced at least 24 inches apart. Edamame seeds take around 7 days to sprout. Once you have at least 4 leaves per seedling, you can start planning to transplant them to your garden.
Start by preparing the soil for your edamame. This legume grows best in rich, loamy soils, with a pH ranging from 6. Use soil amendments such as peat moss or bark if needed.
Soy is similar to beans and other legumes in the fact that it fixates nitrogen in the soil. However, it also means that you need to prepare a nutrient-rich substrate for the young plants to grow into before providing their nitrogen. Make sure to incorporate compost or other organic nutrients into the soil before sowing. They are a perfect warm climate crop, so pick a part of your garden where they get lots of direct sun.
Both seeds and seedlings need plenty of space, so plant them at least 1 foot 30 cm apart. Water your edamame regularly , especially after sowing, when the plants start flowering, and once the seed pods start maturing.
Avoid overwatering, as this can cause root rot and other pathogens, which will kill the plants. Edamame only produces one crop per plant. To enjoy a continuous harvest throughout the year, we recommend sowing seeds several times. A great practice is to start several seedling batches one week apart, for an entire month. Edamame and soy plants encounter the same kinds of pests and problems as peas and beans.
Caterpillars, snails, slugs and the bean beetle will chew the leaves, while aphids can damage the younger stems and leaves by sucking the sap. You might also notice discoloration in the leaves caused by fungal infections, such as powdery mildew or bean rust.
Using chemicals such as pesticides or insecticides can help you protect your edamame crop. They will often negatively impact beneficial insects living in your garden and can also have an ill effect on your health.
There are many natural, organic ways to combat pests, which are better for you and the environment. Manually pick these insects and bugs whenever you see them crawling on the leaves of your edamame plants. Prepare a bucket of soapy water or a water and insecticidal soap mix, and discard them in there. If you spend 5 to 10 minutes each day routinely inspecting your crop, you can stay on top of them without having to use harmful chemicals.
Dislodge large groups of aphids from your plants with a jet of water from your garden hose. If you find any leaves on your edamame plants with red or white spots, cut them off with gardening scissors, and dispose of them away from the plants, to prevent further spread.
Water your soy plants in the morning , from the top, to wash off any spores from the leaves. Given that they fix nitrogen in the soil, soy plants create a rich substrate that is very inviting for weeds. Seeds germinate potentially when temperature remains in range of 60 to 90 F. Sow edamame seeds right after the summer when temperature comes down in range of 60 — 90 F 15 C — 32 C , although soybean can easily tolerate temperature up to F once grown but reduce production in intense heat.
Grow soybean variety that is grown locally or suitable to your climate. There are about 10, cultivars of soybeans of which varieties with green seeds flavor better and are suitable for growing as edamame.
There are varieties with yellow and black seeds, which can also be grown but these are mostly grown for drying out for later use in floor, milk and other products. Sow seeds at a depth of 1 inch, leaving space of 2 inches within rows while spacing the rows 20 to 30 inches apart. For growing edamame choose a spot that is sunny.
Soybean plants require full but also tolerate partial shade. Edamame tolerates poor soil but for optimum growth it must be planted in soil that is fertile, loose and well drained and rich in organic matter. Add lot of compost or farm manure in soil to improve it.
Cold, wet and waterlogged soil inhibit germination and growth so avoid it.
