Propagation Methods
- Cuttings: This is the most common method of propagation. During the growing season in spring or summer, cut branches are planted in water or soil to encourage rooting.

- Watering: Water thoroughly during the early growing season, but maintain moderate moisture after maturity. - Pruning: Pruning can be done in the spring to maintain shape or promote the growth of new branches.

Uses in the Garden

- Pests: Pests such as aphids and moth larvae can be a problem. If the damage is severe, manage the situation by using appropriate pesticides or biological control methods.
- Control Methods: Regular observation is necessary to prevent diseases and pests, and it is important to take appropriate measures immediately upon discovery. Preventively, you can frequently rinse the leaves under running water or use natural pesticides.
