Description
The soybean requires warmth, but thanks to newer early-ripening varieties it now also thrives in mild DACH regions. When harvested immature and green the pods are a popular snack as edamame; when fully ripe they provide protein-rich seeds. Like all legumes it fixes nitrogen in the soil.
Care instructions
Sow the seeds only from mid-May to June into warm soil at a full-sun location; at first planting a rhizobium inoculant helps nitrogen fixation. Keep the soil evenly moist during flowering and pod filling. Harvest the pods for edamame when green and plump, or allow them to fully ripen and yellow for dry beans.

Companion planting
Good neighbors
cabbage family (Brassicaceae)
particularly well establishedLeguminous plants collect nitrogen in the soil, from which Brassicaceae benefit as heavy feeders.

carrot family (Apiaceae)
Peas and beans provide carrot and celery with nitrogen and grow as shallow-rooted plants without competition next to each other.

gourd family (Cucurbitaceae)
Beans and peas enrich the soil with nitrogen, which cucurbits, as heavy feeders, can make good use of.

Rather not
amaryllis family (Amaryllidaceae)
particularly well establishedAllium species inhibit the nitrogen‑fixing rhizobia of legumes through their root exudates, which slows their growth.
