Water: Originating from tropical regions, cat's claw prefers moist, humid environments and regular hydration, with weekly watering recommended. It thrives better outdoors, benefiting from natural rainfall, especially during its active growing season when water demand peaks.

Fertilize: For cat's claw, fertilize bi-weekly with high-phosphorus fertilizer during growth to enhance flowering and fruiting. Use half-strength and adjust feeding with the seasons, reducing in winter. Test soil before application and adhere to label instructions to prevent chemical burns and root damage.

Pruning: Cat's claw features claw-like seed pods and a sprawling habit. Prune in early to late spring to promote bushier growth, remove dead branches, and improve air circulation. Regular pruning reduces invasiveness and boosts flowering; always use clean, sharp tools for best results.

Propagation: Cat's claw is propagated by sowing seeds in well-drained soil, ensuring shallow placement with consistent moisture while avoiding waterlogging. Germination occurs in a couple of weeks, and once seedlings develop true leaves, they can be transplanted into pots or the garden.
