Moltkia requires well-drained soil, preferably with alkaline to neutral pH, and thrives in full sun to partial shade. Water needs are moderate; avoid waterlogging. For planting, loosen the soil, mix in compost, and ensure the hole is twice as wide as the root ball. Space plants according to size guidelines, and water thoroughly after planting. Mulching helps retain moisture. While moltkias have common requirements, individual species may have unique needs, so research on the specific species is advised.
