Water: Adapted to the Mediterranean climate, shrubby crownvetch thrives in dry conditions with moderate drought tolerance. Water sparingly, about once every three weeks, and ensure well-draining soil to prevent waterlogging, especially during the rainy season.

Fertilize: For shrubby crownvetch, apply balanced fertilizer biannually in spring and summer, using a 10-10-10 ratio (max 1/4 cup per mature shrub). Reduce feeding in fall for dormancy preparation. Water thoroughly after application to prevent fertilizer burn and consider granular types for sustained nutrient release.

Pruning: Shrubby crownvetch is a wiry shrub featuring bright yellow flowers and compound leaves. Prune in early spring, removing dead stems and trimming one-third of the plant to boost air circulation and promote robust growth, thereby maximizing flowering potential and enhancing its ornamental value.

Propagation: Shrubby crownvetch propagates effectively via cuttings from healthy, non-flowering shoots. Cut a stem section with leaves, embedding a node in well-draining soil. Maintain moisture and warmth for root growth; optional rooting hormone can enhance this process.
