Soy Bean (Edamame) Seeds - Midori Star, ORGANIC


Glycine max

Midori Star is the new, improved version of Midori Giant, offering the same early production and an even longer harvest window. Plump pods containing 2 to 3 seeds each grow abundantly on bushy, bright green plants. 

Edamame makes a healthy, tasty, high-protein snack or appetizer, and is commonly served in Japanese restaurants, though it is still catching on in the US. The pods are traditionally boiled in salted water or steamed and finished with sea salt, then served whole, and eaten by popping the seeds out of the pods with your teeth. You can also shell the beans out after cooking and add them to salads or rice bowls. The beans are rich and nutty-flavored with a slight crunch, but the pods themselves are tough and should be discarded.

Edamame should be direct seeded in a location with full sun after all danger of frost has passed. Harvest when the seeds have filled out the pods but before the pods begin to turn brown, about 70 days after seeding. 14 gram packet contains a minimum of 20 seeds.

Soy beans only tend to produce a single harvest during a growing season, but are relatively easy to grow and don't require much tending.

Beans need plenty of sunlight to grow properly, so try to choose an area of your garden that receives full sun for your planting site. Since green beans do not do well in heavily-moist soil, you should avoid shaded locations, since shade tends to help soil retain moisture for prolonged periods.

Beans thrive in loamy soil, so if your garden has heavy clay soil or sandy soil, you should amend it with organic material before planting your green beans. Loamy soil is dark and crumbly. Test the soil by squeezing it in your hands. Clay soil stays in a ball and sandy soil falls apart completely. Loamy soil will hold its shape initially yet break apart when touched.

Beans do not require a vast amount of nutrients, but a light application of fertilizer can help your plants produce a better crop. Use a shovel or trowel to mix the fertilizer into the top 3–4 inches of soil. 10-20-10 fertilizer is slightly richer in phosphorus than in nitrogen or potassium, so it is good for producing a strong crop yield. If you use a fertilizer high in nitrogen, then your plant will grow a lot of leaves but few beans.

Plant each seed 1–2 inches deep in the ground. Each seed should also be about 3–6 inches apart and covered lightly with loose soil. If you're planting multiple rows of beans, leave 1–2 feet of room between each row.

Apply mulch to the soil where beans are planted. Standard wood chip mulch or straw works well with green beans. Mulch can prevent the soil from getting too cool or too warm, and it also helps the soil retain moisture.

Sow additional seeds every 2 weeks. You can continue sowing soy bean seeds every 2 weeks if you want a continual harvest that lasts all summer and into fall.

Stop planting new seeds 10 to 12 weeks before the first expected frost.

Pollination, self; Life Cycle, annual; Isolation Distance, 20 feet

As with most beans, cross-pollination is rare, but to ensure variety purity, separate different types by at least 20 feet. Soybean anthers shed pollen before the flowers open, this means that pollination and fertilization are completed before the flower opens. Save seed from healthy, disease free plants when the seed pods are completely dry (the beans will rattle in the pods). Winnow beans from pods/chaff. The hardest and heaviest seeds will be best for replanting, eat the rest.
