Propagation of Magnolia ×soulangiana Soul.-Bod.
Magnolia ×soulangiana Soul.-Bod., commonly known as saucer magnolia, is a deciduous shrub or small tree that is often used as an ornamental plant. Propagation of this plant can be done through various methods:
Propagation through Seeds:
Propagation through seeds is the most commonly used method for Magnolia ×soulangiana Soul.-Bod. Seeds should be harvested from mature cones in the fall. The seeds should be thoroughly dried and then stored in a cool, dry place. In the spring, the seeds can be planted in a mix of peat moss and sand in a shallow container. The container should be kept in a cool, shaded area and should be watered regularly. Germination typically occurs within 30-60 days.
Propagation through Cuttings:
Magnolia ×soulangiana Soul.-Bod. can also be propagated through cuttings taken from softwood or semi-hardwood stems. Cuttings should be taken in the summer and should be approximately 4-6 inches in length. The cuttings should be dipped in rooting hormone and then placed in a mixture of perlite and vermiculite. The container should be placed in a warm area with bright, indirect light. The cuttings should be misted regularly and kept moist until they root, which typically takes 2-3 months.
Propagation through Grafting:
Grafting is another method of propagating Magnolia ×soulangiana Soul.-Bod. In this method, a scion from a desired cultivar is attached to a rootstock. The scion is a piece of stem with buds that will grow into the desired cultivar, and the rootstock is a plant with an established root system. Grafting is typically done in the winter or early spring and requires some skill and expertise.
