80 to 100 days — The plants reach about twenty five inches in height with pods that contain two to three uniform shaped, yellow seeds. They can be harvested at about eighty days for edamame (pronounced "ed-uh-mah-may") or left for another ten to twenty days and harvested as a dry bean. Each packet contains 25 to 30 seeds.
Sow seeds about one inch deep, three to four inches apart. Although you can plant in rows, they can be planted densely and allowed to form a canopy. This will help control weed growth. Soybeans are tolerant of drought and poor soil since they fix nitrogen. They will, however, benefit from fertile soil.
Soybean flowers are perfect (self-fertile) and cross pollination is almost non-existent, making saving seed easy. Allow pods to fully develop and dry on the plants.
