Detailed Explanation of Magnolia liliiflora Grafting Propagation Methods and Techniques
Magnolia liliiflora, also known as Xinyi, Mulan, etc., generally blooms in mid-to-late March. Because Magnolia liliiflora is relatively difficult to cultivate and is a plant endemic to China, its propagation survival rate is also relatively high. Magnolia liliiflora can be propagated by sowing, grafting, cuttings and other methods. What I introduce here for you is the grafting propagation of Magnolia liliiflora.

I. Selection and Treatment of Magnolia liliiflora Rootstock
The rootstock should be selected from inferior varieties at the early or full bud stage that have no flower buds or fewer flower buds. First, saw off the crown from the main branches. The horizontal height from the ground should be similar to avoid imbalance in the vigor of each main branch caused by apical dominance. The upper main branches should be shorter than the lower main branches, and the height of the trunk should be slightly higher than the topmost main branch. The graft union should be selected at a smooth place, and the saw cut should be smoothed with a grafting knife.
II. Selection and Treatment of Scions
The scions should be selected from single plants of superior varieties such as Houbazhang Chuanyu, Damaotao Chuanyu, or Ermaotao Chuanyu. Select one-year-old branches that are robust in growth, well developed, and free of pests and diseases, and collect them as you graft.
Grafting techniques are best carried out from before spring sprouting to the leaf expansion stage. Generally in mid-to-late March, and if the axillary buds do not sprout, the time can also be extended. Grafting methods include: cleft grafting, cut grafting, and bud grafting.
Cleft grafting is mostly used for thick branches. First, split open at the graft union with a cleft grafting knife or a sharp axe, insert a wooden peg into the center of the split, cut the scion to about 10 cm long, sharpen the base into a wedge shape, insert it into the split, and align the outer cambium layers with each other. One scion can be grafted on each side of each split. After grafting, gently pull out the wooden peg. Cut grafting is to make a longitudinal cut slightly into the xylem at the graft union, cut the scion to about 5 cm long, sharpen the two sides of the base into one long and one short cut surface (the long surface about 3 cm, the short surface about 1.5 cm), insert the short surface facing outward into the cut, and align the cambium closely at one end.
Bud grafting is the use of bud grafting to fill gaps where branches are missing within a branch group, so that the branch group is complete.
After grafting by the above methods is completed, the graft union should immediately be wrapped tightly and bound firmly with plastic film strips, and the scion should be left exposed.
III. Post-Grafting Management
About 20 days after grafting, once the scion survives, it can sprout and expand leaves. Note that sprouting buds on the rootstock should be removed in time. For those that do not survive, summer bud grafting should be carried out at a suitable position on the rootstock. When the new shoot of the scion grows to 50 cm, the tip can be pinched off to increase branching and form a crown early.

[Common Questions]How should Magnolia liliiflora be propagated?
[Expert Answer]Magnolia liliiflora is a famous ornamental flowering tree, very suitable for planting in front of halls and behind courtyards in classical gardens, and can also be planted alone or scattered in small courtyards. It has extremely high ornamental value. I believe many flower and plant enthusiasts want to know how Magnolia liliiflora is propagated. In fact, the main propagation methods of Magnolia liliiflora are sowing, grafting, and cuttings. The propagation methods of Magnolia liliiflora are introduced as follows.

I. Propagation by Sowing
After the seeds of Magnolia liliiflora mature in September to October, sow them immediately after collection. Before sowing, soak the seeds in warm water at about 50°C. Sow in furrows. Use fertile sandy loam for the seedling bed. After sowing, cover with 2 cm of soil, water thoroughly, cover with grass, and keep the soil moist frequently. Generally, seedlings emerge after about 2 months, and in the second spring after the soil thaws, divide and transplant.
II. Propagation by Grafting
When grafting Magnolia liliiflora, 2- to 3-year-old Magnolia seedlings should be selected as rootstock. Bud grafting is carried out in July to August, and cut grafting is carried out in autumn. After cut grafting, the scion should be completely covered with soil, and the covering soil should be removed in late spring of the second year. Cut grafting can also be carried out in a greenhouse, and after grafting, store in moist sand. After the graft union heals, transplant before sprouting in the following spring.

III. Propagation by Cuttings
Before cutting Magnolia liliiflora, dip the base of the cuttings in rooting powder or soak them in a 25 ppm naphthalene acetic acid solution for 20 hours, which can promote rooting and improve the survival rate. Collect cuttings from one-year-old branches on the mother plant of Magnolia liliiflora. The cuttings are 15 cm long, retain 2 leaves at the upper end, and cut off 1/3 to 1/2 of the leaf surface of each leaf. After cutting, pay attention to shading and watering.
IV. Ordinary Layering
Ordinary layering is best carried out in February to March. Cut halfway into the base of the branch to be layered, then cut upward for a section, insert a tile in the middle, then gently press it into the soil without breaking it. Insert a U-shaped thick iron wire into the soil to fix it and prevent it from lifting, then pile soil on top. For spring layering, once root buds emerge, it can be cut off and transplanted.

V. Air Layering
Before the beginning of the dog days, select robust and disease-free young branches (1.5 to 2 cm in diameter) on the mother plant, cut a slit at the lower part of the branch fork, then cover with a bamboo tube or bottomless clay pot, fill it with culture soil, tie it tightly outside with fine string, being careful not to disturb it, and spray a small amount of water frequently to keep it moist. New roots can grow around May of the following year, then remove and plant in place.
[Editor's Conclusion]Magnolia liliiflora likes light, prefers a dry environment, and likes fertility, so special attention should be paid during propagation. The above has introduced the propagation methods of Magnolia liliiflora for everyone, and I hope it can be helpful to everyone!
