Water: Rock moltkia thrives in rocky terrains, requiring balanced moisture retention and drought tolerance. Water weekly and ensure well-draining soil to prevent waterlogging. This species' resilience mirrors its native habitat, adapting well to outdoor conditions and infrequent hydration.

Pruning: Rock moltkia features vibrant blue flowers and a compact form. Prune in early to late spring to enhance shape, foliage density, and airflow, reducing disease risk. Remove dead branches and use clean, sharp tools for optimal healing.

Propagation: Rock moltkia propagates best through cuttings taken from healthy, non-flowering stems just below a node, using clean tools to prevent infection. Remove lower leaves, apply rooting hormone, and plant in a sterile, well-draining medium to promote optimal root growth.
