Rows: 5" (15cm) with 5" (15cm) row gap (minimum)

Sow and Plant
Plant seeds from late spring to early summer. Soybeans must have warm soil to germinate and grow. Poke holes into a cultivated bed or row to plant soybean seeds about 2 inches (5 cm) apart and one-half inch (1 cm) deep. Thin to 6 inches (15 cm) apart in all directions.
Our Garden Planning Tool can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes
Soybean cover crops are used primarily to add nitrogen to poor soil.
|
Harvesting
Chop down or pull up plants just as they begin to flower. Nitrogen nodules left behind in the soil add fertility.
|
Troubleshooting
Soybeans are very attractive to deer and Japanese beetles.
