Dune bean (Vigna marina)

Dune bean

Also known as: Field bean

Dune bean (Vigna marina) is a scrambling salt-tolerant plant that simply loves the beach. Its scientific name marina refers to its preferred marine habitat. This plant's dense growth means that it is classed as minorly invasive in some coastal locations. However, in other locations this dense growth is appreciated, as it can stabilize loose sand.

Water: Dune bean thrives in coastal habitats and has moderate drought tolerance. It prefers steady moisture but can withstand brief dry spells, requiring weekly watering. Planting dune bean in well-draining soil is essential for preventing waterlogging and supporting its growth cycles.

Fertilize: Fertilize dune bean bi-monthly with balanced nutrition containing nitrogen, phosphorus, and potassium. Use granular or liquid forms as per label instructions, adjusting rates during active growth. Apply slow-release variants and water soil before and after to prevent root burn, promoting a robust plant health.

Pruning: Dune bean flourishes in coastal areas, featuring sprawling growth and bright flowers. Prune in early to late spring to maintain size and health, removing dead/diseased branches and long stems. Regular pruning improves air circulation and reduces disease risk. Use clean, sharp tools for optimal results.

Propagation: Dune bean is a coastal-adapted leguminous vine. For propagation, sow seeds in well-draining sandy soil with ample sunlight. Prior scarification enhances germination. Maintain consistent moisture initially; once established, dune bean tolerates dry conditions. It's pest-resistant and low-maintenance, ideal for novice gardeners.
