Water: Periwinkles thrives in tropical conditions, requiring consistently moist but not waterlogged soil. Water twice a week to maintain hydration. As an evergreen, it needs steady moisture year-round, particularly indoors where humidity can be regulated for optimal foliage health.

Propagation: Periwinkles propagate via seeds, stem cuttings, or division. Successful propagation requires warm temperatures, high humidity, and well-draining, neutral to slightly acidic soil. Use hormone treatments for cuttings, ensuring bright, indirect light. Rooting can be challenging, necessitating careful attention to disease and environmental conditions.
