Propagation methods
Propagation of Philadelphus pumilus Rydb. var. ovatus Hu can be achieved using different methods which are:
Seed propagation
Propagation through seeds is an easy way to produce Philadelphus pumilus Rydb. var. ovatus Hu. The seeds can be collected from the plant once they are mature.

Cuttings propagation
Cuttings are another propagation method that can be used for Philadelphus pumilus Rydb. var. ovatus Hu. Semi-hardwood cuttings should be taken in late summer or early autumn since it is the best time when the plant has just finished flowering. A cutting with a length of 4 to 6 inches and a width of 0.1 to 0.2 inches can be used. Dip the cutting's base in a rooting hormone and plant it in a soilless mixture that is moist but not waterlogged. Cover the pot with a plastic bag and place it in a warm, bright area. It takes about 4 to 6 weeks for roots to develop fully. Once the roots have developed, remove the plastic bag and transfer the cutting into a pot or to the garden.
Division propagation
Division is a propagation method that is useful when a mature plant has overgrown where it is planted. The plant can be dug up, and the roots can be separated into smaller sections, each of which is replanted in well-draining soil.
