The soybean is a versatile plant suitable for sweet desserts to savoury dishes. With so many uses, soybeans are a perfect addition to any home garden. Like many other legumes, soybeans are hardy and tolerant of most soil types and capable of surviving almost any type of weather. As long as you plant the seeds properly in early spring, soybean plants will thrive throughout the summer months and produce bundles of beans.
Choose a planting site that gets partial shade. Each soybean plant should be spaced four inches apart, with each row spaced 30 inches apart, so take this into consideration when choosing a planting site.
Remove all weeds and aerate the soil to a depth of four inches. The soil needs to be loose to ensure adequate drainage. If the soil has a high clay content, mix two inches of compost into the soil.
Water the soil so it is moist to a depth of six inches. The soybeans need moisture in order to germinate.
Plant the seeds between one and one and a half inches deep. If the soil is sandy, plant them two inches deep. Each seed should be spaced two inches apart, and each row spaced 30 inches apart.
Keep the soil moist at all times throughout the growth cycle of the plants. Depending on the conditions in your region, it can take anywhere from three to five months for the plants to reach maturity.
Harvest the soybeans once the pods are between two and three inches long, with round plump soybeans on the inside. To harvest them, simply snap the pods off of the plant.
