Vegetative propagation is another method that can be used to propagate Selago trinervia E.Mey., and can be done through the following techniques:
- Softwood or semi-hardwood cuttings taken from healthy, mature plants can be used for propagation.
- Make four to six-inch-long cuttings and remove the leaves from the lower half.
- Dip the cuttings in rooting hormone powder to stimulate root growth.
- Place the cuttings in moist, well-draining soil or a mix of peat and perlite.
- Keep the soil moist and covered with plastic to retain humidity until the cuttings take root.
- Once the cuttings have rooted, transplant them into individual pots or directly into the garden.
Propagation of Selago trinervia E.Mey. through seed or vegetative methods can be a rewarding experience for gardeners and enthusiasts who want to propagate and grow this beautiful plant. The propagation process, however, requires patience and careful nurturing to ensure the successful growth and establishment of Selago trinervia E.Mey.
Disease and Pest Management for Selago trinervia E.Mey.
