Japanese Kerria thrives in well-drained soil with partial to full shade, although it can tolerate full sun in cooler climates. Regular watering is essential during dry spells to maintain soil moisture. Prune after flowering to encourage bushy growth and remove any dead or weak stems. Fertilize in early spring with a balanced fertilizer to promote healthy blooms. Propagate through softwood cuttings in late spring or early summer for best results.
