Propagation of Labordia fagraeoidea Gaud. var. humei Sherff
Labordia fagraeoidea Gaud. var. humei Sherff can be propagated through different methods such as seed propagation and vegetative propagation.
Seed propagation
The seeds of Labordia fagraeoidea Gaud. var. humei Sherff can be collected from mature fruits that have turned brown. The collected seeds should be cleaned to remove any pulp or debris and stratified to break their dormancy. Stratification can be achieved by storing the seeds in a moist medium at a temperature of 20-25°C for approximately 4-6 weeks. After stratification, the seeds can be planted in potting mix in a greenhouse or indoors. The seedlings can be transplanted in a well-prepared garden bed after they have reached a height of 5-8 cm.
Vegetative propagation
Labordia fagraeoidea Gaud. var. humei Sherff can also be propagated vegetatively through stem cuttings and layering.
Stem cuttings
Select semi-hardwood stem cuttings with at least 2-3 nodes from healthy, disease-free plants. Remove the lower leaves and dip the cuttings in rooting hormone to enhance rooting. Plant the cuttings in a rooting medium consisting of a mixture of peat moss and perlite. The cuttings can be covered with a plastic bag or placed in a mist chamber to maintain high humidity and prevent moisture loss. The rooted cuttings can be transplanted to a well-prepared garden bed or individual pots.
Layering
Layering involves bending a low-growing stem of the Labordia fagraeoidea Gaud. var. humei Sherff plant towards the ground and covering it with soil while still attached to the mother plant. The covered part of the stem will eventually produce roots and can be separated from the mother plant once it has established itself. Layering is particularly suitable for Labordia fagraeoidea Gaud. var. humei Sherff as it helps to maintain the genetic characteristics of the parent plant.
