This method is best done in the spring when the plant is actively growing.
Cuttings
Cuttings are another way to propagate Hypericum quartinianum A.Rich. Simply take a stem cutting from an established plant and remove the leaves from the lower half. Dip the end of the cutting in rooting hormone and plant it in well-draining soil. Keep the soil moist and at a temperature of around 21-24°C, and the cutting should start growing roots within a few weeks. Once it has a good root system, you can transplant it to a larger pot or directly into the garden.
Overall, Hypericum quartinianum A.Rich. is a relatively easy plant to propagate. Whether you choose to use seeds, division, or cuttings, make sure to provide the new plants with plenty of water and a well-draining soil to thrive.
