How to Propagate Viburnum macrocephalum? A Detailed Guide to Common Propagation Methods
Viburnum macrocephalum is a deciduous or semi-evergreen shrub in the genus Viburnum of the Caprifoliaceae family. Its inflorescence consists of large white flowers shaped like a hydrangea ball, very beautiful, and many people like it. So, how to propagate Viburnum macrocephalum?
1. How to propagate Viburnum macrocephalum?
Viburnum macrocephalum can be propagated by sowing, division, cuttings, layering and grafting.
1. Sowing: seed propagation is commonly used. Collect seeds in November, pile them up for after-ripening, wash the seeds clean, and stratify them at low temperature until sowing the following spring. Cover with a slightly thick layer of soil, then put grass on top. In June of that year, some will germinate and emerge, and at this point the grass can be removed for shading.
2. Division: best done in early spring before the plant sprouts, separating rooted branches from the parent plant to propagate.
3. Cuttings: generally take softwood cuttings during the plum rain season.
4. Layering: use the air layering method in spring; roots usually form in June or July, and the layers can be separated and replanted the same year.
5. Grafting: in early March (before the buds break), take branches from a flowering parent tree, cut a section about 5 cm long as the scion, keep the terminal bud, and use the high grafting method. After grafting, place in a shaded spot; once the scion's buds produce leaves, place it directly in sunlight. After it survives, it can bloom in the first year.
2. When does Viburnum macrocephalum bloom?
Viburnum macrocephalum blooms in April-May. It is a deciduous or semi-evergreen shrub in the genus Viburnum of the Caprifoliaceae family, reaching up to 4 m tall, with grayish-brown or grayish-white bark. The buds, young shoots and petioles are densely covered with grayish-white or yellowish-white tufted short hairs. The leaves are ovate to elliptic or ovate-oblong. The cyme is 8-15 cm in diameter, entirely composed of large sterile flowers, with flowers borne on the third-order radiating branches and a white, rotate corolla.
