Propagation of Morella salicifolia subsp. salicifolia
Morella salicifolia subsp. salicifolia, also known as willowleaf wax myrtle, is a dioecious shrub or small tree that is native to eastern Africa. The plant can be propagated by seeds or by cuttings.
Propagation by Seeds
The seeds of Morella salicifolia subsp. salicifolia can be collected from ripe fruits, which are black and globose. The seeds should be cleaned and stored in a cool, dry place until it is time to sow them. The ideal time to sow the seeds is in the spring, after the last frost date. The seeds should be soaked in water for 24 hours prior to sowing to help increase germination rates.
The seeds can be sown in pots or trays that are filled with a well-draining seed-starting mix. The seeds should be covered with a thin layer of soil and kept consistently moist until they germinate, which typically occurs within two to four weeks. Once the seedlings have emerged, they can be transplanted into individual pots and grown on until they are large enough to be planted in their permanent location.
Propagation by Cuttings
Morella salicifolia subsp. salicifolia can also be propagated by cuttings. The best time to take cuttings is in the early spring, just as the new growth is beginning to emerge. Take cuttings that are 4-6 inches long and have several nodes on them. The cuttings should be dipped in rooting hormone and planted in well-draining potting soil.
The cuttings should be kept moist and warm until they have rooted, which typically takes 4-6 weeks. To encourage root growth, cover the cuttings with a plastic bag or place them in a propagator. Once the cuttings have rooted, they can be transplanted into individual pots and grown on until they are large enough to be planted in their permanent location.
