Most prefer full sun on well drained soil. Insect pest and disease problems are rare, root rot may occur on poorly drained sites. Propagation is from softwood cuttings during early summer ( non flowering shoots ) which once rooted will need extra protection such as a cold frame or cool greenhouse during their first winter.
Easy to grow, Hypericums are not normally eaten by deer.
