How to Grow Purple Winged Bean
-
Soil preparation: Ensure the soil is well-drained and slightly acidic to neutral. Mix in organic compost to enhance fertility.

Fertilizing: Use a balanced fertilizer in early spring or apply organic compost during the growing season to ensure optimal growth and pod production.
