Propagation
It is possible to propagate the peonies using seeds and by the division of tubers.
Propagation by seed
The seeds of species Peonies need exposure to two chilling seasons with a warm spell in between to ensure germination. The seeds are double-dormant and the roots will develop in the first chilling season while the stem and leaves appear during the second chilling season. You can sow the ripe seeds in late summer or during autumn in containers filled with potting soil.
Propagation by division
The best time to divide Peony tubers is during autumn. From the clumps, remove the sections of the crown with at least 3 growth buds and replant the buds in the soil. It will take one to two years for the new plant to establish. Deep planting or planting in a shady position all day will result in a lack of flowers.
Problems
The plants are generally hardy. The plant and its flowers are prone to fungal disease like botrytis blight and leaf blotch. They are also prone to ring spot virus and Verticillium wilt and stem rot as well.
