|Propagation methods: crown division, cuttings, grafting, seeds. Scrub can be divided then replanted. Leaves, as well as soil from roots should be removed. Unhealthy roots are cut off; healthy roots are cut off and left 15 cm long. Scrub can be divided into parts with 3-5 crown buds. 4-5 years old scrubs are the best for this propagation method. It is advisable to soak tubers in clay which contains from 0.5 to 1.0 percent copper sulphate.
The flower is propagated by cuttings before blooming in June. Top of stem should be nipped off. Leaves cuttings with a 2 cm long Stem istaken.
Woody stem (2 cm long) is cut lengthwise and leaves are shortened. Growth stimulators can be used as well. Rooting lasts for 2 months at 25°C and at 90 percent relative humidity.
Peonies do not come true from seed (the only exception being large populations of species peonies that are isolated from other peonies) so each seedling is something new. The popular cultivars of yesterday and today do not come true from seed.
Grafting is by far the most used method of propagation for tree peonies. Essentially a small section of tree peony branch is grafted onto a section of a herbaceous peony root. The herbaceous root serves as a nurse root until the tree peony produces its own root system.|
