What are the propagation methods for Yulan magnolia? A detailed guide to the latest techniques

Yulan magnolia, also known as magnolia and purple magnolia, is a plant endemic to China, mainly distributed in the southern regions. Its plant form is attractive, its flowers are gorgeous, and its fragrance is light and elegant, giving it high ornamental value. In addition, it is a traditional Chinese medicinal material and an extremely precious flowering tree. So how should Yulan magnolia be propagated? Let's take a look at the detailed introduction below.

1. Seed propagation

Seed propagation can be done by spring sowing or autumn sowing. Before sowing, soak the seeds in warm water with plant ash for 3-5 days, rub off the waxy layer on their surface, then soak them in warm water for one day, remove them and cover them with a layer of rice straw, and water frequently to keep them moist. When the seeds split open, they can be sown. Use the drill sowing method, open furrows on the seedbed surface, scatter the seeds into the furrows, and cover with about 8 cm of soil. After sowing, keep the soil moist. For one month after emergence, provide shade, water in time, and do a good job of weeding and fertilizing. After two years of growth, they can be planted out.

2. Cutting propagation

Cutting propagation is generally carried out in May-June. Select vigorous perennial branches from young trees, cut them into 10-12 cm lengths, leave two leaves at the lower end and keep a bud at the lower end, dip the base in rooting powder, and then insert the cuttings. When inserting, use a row spacing of 15 cm × 4 cm, turn the leaves to one side, water thoroughly once after insertion, then cover with plastic film, and then cover with straw curtains for shade. After the cuttings survive, do a good job of weeding, topdressing, and providing light. After about one year, they can be planted out.

3. Division propagation

The root system of the Yulan magnolia plant will grow suckers. In winter dormancy or early spring, dig out the old plant with suckers, divide it into several plants, and each plant must have roots to survive. Plant immediately after digging. On the ground, dig holes at a row spacing of 150 cm × 200 cm, transplant one plant per hole, and spread out the root system. Cover with soil and firm it so that the roots and soil are closely connected, then water thoroughly once to help survival.

4. Layering propagation

In June, select young tender branches on the mother plant that are growing vigorously and free of pests and diseases. At the branching point, peel off the bark of the branch, then cover it with a slender bamboo tube or a bottomless clay pot, insert the branch into the tube, and stuff fertile soil into the tube. Tie the outside tightly, and water frequently afterward to keep the soil moist. After about one year, roots will form inside the tube. At this time, it can be separated from the mother plant to become a new plant, and then transplanted elsewhere.
