Propagation Methods for Canarina zanguebar Lour.
Canarina zanguebar Lour. can be propagated through both sexual and asexual methods.
Sexual Propagation
This can be done by seed, which is usually sown in the fall or winter. The seeds should be soaked in water for 24 hours before sowing. They can be sown outside in well-draining soil or inside in pots.
Once the seeds have germinated, they should be kept in a warm, brightly lit area. When the seedlings have grown two to three sets of true leaves, they can be transplanted.
Asexual Propagation
Canarina zanguebar Lour. can also be propagated through division or cuttings. Division should be done in the fall when the plant is dormant. The rhizomes should be carefully dug up and separated, making sure that each section has at least one healthy shoot and a good root system. They can then be replanted in their desired location.
Softwood cuttings can be taken in the spring or early summer, while hardwood cuttings are taken in the fall or winter. Cuttings should be taken from the tips of healthy shoots and should be two to three inches long. The leaves should be removed from the lower half of the cutting and it should be dipped in rooting hormone before being planted in well-draining soil. The cuttings should be kept in a warm, humid area until they have rooted, and then gradually hardened off before being transplanted.
