How to Propagate Magnolia? Introduction to Several Common Propagation Methods
Magnolia, also known as Yulan magnolia and white magnolia, is a famous ornamental plant and traditional flower of the Magnoliaceae family, genus Magnolia. It is native to various provinces in central China, prefers warm and humid environments, is very sensitive to temperature, has a certain resistance to low temperatures, and can safely overwinter at -20C. Its propagation methods mainly include seed propagation, grafting propagation, cutting propagation and layering propagation, etc. Let's take a look together below!
Magnolia Seed Propagation
Magnolia is best sown in autumn. When the seeds mature in September-October, sow them immediately after harvesting. Alternatively, the seeds can be stored in sand until the following spring in March-April for sowing. Before sowing, soak the seeds in warm water at about 50°C to remove the waxy layer on the outside of the seeds. To remove the waxy layer, you can either rub them with sand, or soak them in 0.5% alkaline water or plant ash water for 1-2 days. Sow in furrows in rows. Choose 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 regularly. Generally, seedlings emerge after about 2 months. Shade is needed in summer, and protection from freezing is needed in winter. Divide and transplant after the soil thaws in the following spring.
Magnolia Grafting Propagation
Grafting propagation is the most commonly used method for propagating magnolia. It can not only maintain the quality of excellent varieties, but also allow flowering 2-3 years earlier than seedling plants. When grafting, select 2-3 year old magnolia seedling plants as rootstock. Bud grafting is carried out in July-August, and cut grafting is carried out in autumn. After cut grafting, cover the entire scion with soil, and remove the covering soil in late spring of the following year. Cut grafting can also be done in a greenhouse (autumn or winter), and after grafting, store in moist sand. After the graft union heals, transplant before sprouting in the following spring.
Magnolia Cutting Propagation
Because magnolia cuttings do not easily root and have a low survival rate, this propagation method is generally rarely used. However, if before cutting the base of the cuttings is dipped in rooting powder or soaked in a 25ppm naphthalene acetic acid solution for 20 hours, rooting can be promoted and the survival rate improved. Cut in June-July. Collect cuttings from 1-year-old branches on the mother plant of white magnolia. The cuttings should be 15 cm long, retain 2 leaves at the upper end, and cut off 1/3-1/2 of each leaf blade. After cutting, pay attention to shading and watering, and keep the soil moist regularly.
Magnolia Layering Propagation
Magnolia layering propagation is also a relatively commonly used propagation method, mainly divided into ordinary layering and air layering.
1. Ordinary layering: Ordinary layering is best carried out in February-March. Cut halfway through the base of the branch to be layered, then cut upward a section, insert a piece of tile in the middle, then gently press it into the soil without breaking it. Insert a thick "U"-shaped wire into the soil to fix it and prevent it from lifting. Then pile soil on top. Layer in spring, and once root buds appear, it can be cut off and transplanted separately.
2. Air layering: Before the dog days, select healthy and disease-free young branches (1.5-2 cm in diameter) on the mother plant, cut a slit at the lower part of the fork, then cover with a bamboo tube or a bottomless clay pot, fill it with culture soil, tie it tightly on the outside with fine rope, be careful not to disturb it, frequently spray a small amount of water to keep it moist. New roots can grow around May of the following year, then remove and plant in place.
Introduction to Several Common Propagation Methods for White Magnolia and Precautions for Its Propagation
When it comes to magnolia flowers, I believe everyone is familiar with them. Magnolia is a common woody plant. Its flowers are beautiful in color and charming in fragrance, and it is deeply loved by many flower lovers. So, do you know how magnolia is propagated? What precautions are there for its propagation? Today, the editor will introduce it to you in detail.
White Michelia Grafting Propagation:
White michelia is often propagated by grafting. Generally, 2-3 year old seedlings of Magnolia biondii or Michelia champaca are used as rootstock. In June, approach grafting can be carried out on the branches of the white michelia plant. The cuts on both should be 3-5 cm long. After joining, tie tightly with plastic strips so that the cambium layers of both are closely combined. After about 3 months, the rootstock and scion have basically grown together, and they can be cut away from the mother plant. Remove the upper part of the rootstock, and it becomes a new plant.
White Michelia Layering Propagation:
White michelia layering propagation is also a relatively commonly used propagation method, mainly divided into ordinary layering and air layering.
1. Ordinary layering: Ordinary layering is best carried out in February-March. Cut halfway through the base of the branch to be layered, then cut upward a section, insert a piece of tile in the middle, then gently press it into the soil without breaking it. Insert a thick "U"-shaped wire into the soil to fix it and prevent it from lifting. Then pile soil on top. Layer in spring, and once root buds appear, it can be cut off and transplanted separately.
2. Air layering: Before the dog days, select healthy and disease-free young branches (1.5-2 cm in diameter) on the mother plant, cut a slit at the lower part of the fork, then cover with a bamboo tube or a bottomless clay pot, fill it with culture soil, tie it tightly on the outside with fine rope, be careful not to disturb it, frequently spray a small amount of water to keep it moist. New roots can grow around May of the following year, then remove and plant in place.
White Magnolia Seed Propagation:
For sowing and seedling raising at the end of September or early October, harvest the mature fruit, take out the seeds, soak them in plant ash water for 1-2 days, then rub off the waxy aril, and wash clean with water before sowing. Alternatively, after washing the seeds, stratify them with moist sand for cold storage, otherwise the seeds easily lose their germination ability. Sow in indoor pots in March of the following year, and seedlings will emerge in about 20 days.
White Michelia Cutting Propagation:
White michelia can also be propagated by cuttings, but white michelia has poor regenerative ability, and cuttings do not easily root and survive, so this method is mostly not adopted. There are relatively many propagation methods for white michelia. The more commonly used ones are grafting and layering, while sowing and cutting are used less often. However, for home cultivation, grafting and layering are sufficient.

How Many Kinds of Magnolia Are There, and What Are the Common Types of Magnolia
Magnolia is a plant of very high value. Not only are its flowers fragrant and beautiful when in full bloom, it is also a plant of very high value. Magnolia is not as delicate and gorgeous as roses, nor as noble and pure as lotuses. It simply blooms lightly and leaves lightly, leaving its beauty for humans to admire. So, how many kinds of magnolia are there? What are the common types of magnolia? Now let the editor introduce them to you.
How Many Kinds of Magnolia Are There
Magnolia is a deciduous tree of the Magnoliaceae family. It is native to various provinces in central China, and is now cultivated in Beijing and south of the Yellow River basin. There are many types of magnolia. Common ones include white magnolia, purple magnolia and southern magnolia, etc. Next, let's introduce the common types of magnolia.
Common Types of Magnolia
Southern Magnolia
Evergreen tree, belonging to the Magnoliaceae family, genus Magnolia, evergreen tree, leaves leathery, underside covered with rust-colored tomentum, surface glossy, margins slightly revolute, leaves 10-20 cm long. Another variety is called narrow-leaved southern magnolia, with narrower and longer leaves, fewer hairs on the underside, and slightly stronger cold resistance. Flowers large and white, fragrant, 20-30 cm in diameter, flowers usually 6 petals, flowers as large as lotus, flowering period May-July, seed coat red, fruit ripens September-October.
Usually southern magnolia can grow to 30 m, but ordinary magnolia can only grow to 16-23 m. The crown is ovate-conical, young branches and buds both have rust-colored tomentum, and the tree is majestic and magnificent. Southern magnolia has a beautiful tree shape and large fragrant flowers. It is an excellent environmentally friendly courtyard tree, suitable for factory and mining area greening, and is closely related to human survival.
Purple Magnolia
Deciduous shrub, up to 3 m tall, often clumping. Buds have grayish-brown fine hairs; young branches purplish-brown. Leaves obovate or elliptic-obovate, 10-18 cm long, 4-10 cm wide, apex acute or acuminate, base cuneate, underside with soft hairs along the veins.
Flowers open before leaves or rarely at the same time as leaves, large, bell-shaped; calyx segments 3, lanceolate, pale purplish-brown, 2-3 cm long; petals 6, oblong-obovate, 8-10 cm long, outside purple or purplish-red, inside white; filaments and carpels purplish-red; style 1, apex pointed, slightly curved. Aggregate fruit oblong, 7-10 cm long, pale brown.
The bark, leaves and flowers can be used to extract aromatic concrete; the flower buds are used as medicine to treat headache, sinusitis, etc., and also have the effect of lowering blood pressure. The flowers contain volatile oil and a small amount of alkaloids.
White Magnolia
Deciduous tree, up to 25 m tall, diameter up to 200 cm. The crown is narrowly ovate when young, and broadly ovate or loosely broad-ovate when mature. Large trees of seedling origin often have an obvious trunk, a sturdy body, majestic and upright, vigorous growth, long internodes and sparse branches, but the number of flowers is somewhat sparse.
Grafted plants often show multiple trunks or low-branching trunks, with short internodes and dense branches, and a smaller and more delicate tree body, but with clusters of flowers, appearing pure white from a distance and extremely charming. Therefore, white magnolias of different origins have different charms in garden applications. In small or enclosed gardens, grafted plants should be used for solitary planting or small clump planting to reflect an antique elegance; while in scenic tourist areas, seedling plants should be selected to express a rough and simple style.
Yellow Magnolia
Belonging to the Magnoliaceae family, genus Magnolia, deciduous small shrub. It is a very precious ornamental plant. The flower colors of plants in the genus Magnolia are mostly white, pink and purplish-red. Yellow magnolia flowers are extremely rare. Yellow magnolia blooms in late spring.
Growing environment: sunny to semi-shady; ordinary garden soil is sufficient; good drainage; no pruning needed. It can be planted in both north and south. Yellow magnolia flowers are golden yellow and bloom late, so there is no need to worry about damage from early spring frost.
Soulangeana Magnolia
Plant of the Magnoliaceae family, genus Magnolia. Also known as cinnabar magnolia and purple sand magnolia. It is a hybrid of white magnolia and purple magnolia, cultivated from 1820-1840. Morphological characteristics: deciduous small tree, 6-10 m tall. Young branches hairless. Leaves obovate, apex shortly acute, midrib base on the leaf surface often hairy, underside more or less pubescent, petiole pubescent, stipule scar one third the length of the petiole.
Flowers open before leaves, large and bell-shaped, purple or red, white inside, fragrant, tepals 6-9. Fruit black, with white lenticels, seeds dark brown. Flowering period February-March, fruit ripening period September-October.
Ecological habits: sun-loving tree, slightly shade-tolerant, best grown in acidic, fertile and well-drained soil, and can also grow in slightly alkaline soil. Likes fertilizer, fleshy roots are not tolerant of waterlogging. Likes humid air, relatively strong cold resistance, sensitive to temperature. Not tolerant of pruning. Lifespan can reach more than a thousand years. Seedling cultivation: mainly graft propagation, also can use layering and cutting propagation. Greening use: Soulangeana magnolia is an excellent ornamental tree species.
Red Magnolia
A new variety bred by the New Variety Research Institute of Magnoliaceae, blooming three times each year in spring, summer and autumn. In midsummer in China there are few flowers, and even fewer woody flowering plants. This variety well meets the needs of this period. Red magnolia can be planted alone in courtyards or in groups, and has now trended toward use as a street tree.
The key points for cultivating red magnolia are that it likes light, fertilizer and water, and fears waterlogging and root rot. When planting in low-lying areas in the south, the position should be raised. In alkaline land in the north with a pH value of 7.5-8.3, a 3‰ ferrous sulfate solution can be used 3-4 times a year for neutralization. Because the new roots of Magnoliaceae plants are fleshy roots and wounds heal slowly, careful management is needed after transplanting.
From ancient times to the present, magnolia has been a flower plant of relatively high value. From the above introduction, we can see that its value is mainly reflected in two aspects: landscaping and food use. Magnolia has a beautiful appearance, and as a garden ornamental plant it is fully deserving of that.
In addition, magnolia is also rich in vitamins, amino acids and various trace elements, and has the effects of dispelling wind-cold and regulating the lungs. As a food ingredient, making magnolia cakes, magnolia flower salad, magnolia flower rice porridge, etc. are all excellent dishes.
