How to sow:

Winged Bean thrives in hot humid tropics; however, it can be grown with success as an annual in temperate regions if day-neutral strains are chosen.
Scarify the seeds (nick or scratch the seed coat or rub seeds on a rough surface) and soak overnight prior to planting.
Plant seeds 2-2.5 cm (1 in) deep, 7-8 cm (3 in) apart in rows 30-40 cm (12-15 in) apart, in a sunny location, after danger of frost is past.
Winged Bean is a vigorous vine; use a trellis support for improved leaf and pod yields.
Plants allowed to trellis and those with plucked flowers have enhanced tuber production.
Winged Bean does well in a variety of soils except in sand or high salinity environments.
Manuring or fertilizing every 2-3 weeks is recommended to sustain pod development.
Wood ash or other potash fertilizer enrichment often improves yields.
