  • Kerria grows in fertile, well-drained soil preferring full sun for the best flowers or partial shade.
  • Prune by removing several older flowering shoots at the base of the plant each year after flowering to make room for new shoots and keep the shrub under control. If left it can become straggly.
  • Propagation by taking greenwood cuttings in summer or layer stems
  • Plants can be divided in Autumn.
