How to Propagate Magnolia: A StepbyStep Guide
How to Propagate Magnolia?
To propagate magnolia, there are several methods that can be used.
One method is through clonal propagation using softwood cuttings.
This involves taking 6-8 inch cuttings from new shoots, removing most of the leaves except for two at the tip, and placing them in water to prevent drying out.
A rooting bed is prepared using a container filled with a rooting medium such as sand or peat.
The cuttings are then dipped in rooting hormone, placed in the medium, and covered with plastic for humidity.
In a few weeks, strong roots should develop for transplantation.
Another method is air layering, best done in early spring or late summer.
This process involves making a cut on a one-year-old shoot, applying rooting hormone, and wrapping moist sphagnum moss around the wound.
The moss is kept moist until roots develop and protrude through it, at which point the shoot is cut off and planted.
Other methods include propagation by seed, grafting in winter or spring, and chip budding in summer.

Did You Know?
1. The magnolia tree is believed to be one of the most ancient flowering plants, with fossils dating back over 20 million years.
2. Although magnolias are commonly associated with the southern United States, they are actually native to Asia and the Americas, and can be found growing naturally in countries such as China, Japan, and Brazil.
3. The bright red seeds of the magnolia tree are not only decorative but also edible. In some cultures, they are used in traditional medicine and various culinary dishes.
4. The magnolia flower is actually a composite flower, consisting of both male and female parts. This unique feature allows the flower to be both self-pollinating and cross-pollinating, increasing its chances of reproduction.
5. Not all magnolias have fragrant flowers. While many species produce a delightful scent, some varieties, known as tulip magnolias, do not have a noticeable fragrance. Instead, they captivate with their vibrant colors and interesting petal shapes.
Clonal Propagation By Softwood Cuttings
Propagation of magnolia trees can be achieved through various methods, one of which is clonal propagation by softwood cuttings. This method involves taking 6-8 inch cuttings from newly developing shoots. It is important to ensure that the cuttings do not dry out, so they should be placed in water immediately after being cut to maintain their moisture content.
To prepare the rooting bed for the cuttings, a plastic container filled with a rooting medium such as sand, peat, or vermiculite should be used. This will provide a suitable environment for the development of strong roots. Before placing the cuttings in the rooting medium, all leaves except for two at the tip should be removed. This encourages the energy of the plant to focus on root development rather than sustaining excessive foliage.
To further enhance root growth, the cuttings should be dipped in rooting hormone before being inserted into the prepared rooting bed. Making holes in the medium and placing the cuttings in these holes will ensure proper contact between the cutting and the rooting medium. To create an environment that promotes high humidity, the cuttings can be covered with a clear top or plastic. This will help retain moisture and improve the chances of successful propagation. With proper care and attention, the cuttings should develop strong roots in a matter of weeks, at which point they can be transplanted into their permanent growing location.
Air Layering
Another effective method for propagating magnolia trees is through the technique of air layering. This method is best performed in early spring or late summer when the tree is actively growing. To initiate the process, a one-year-old shoot should be selected, and a 1/3 to 1/2 inch cut should be made on the shoot. Applying rooting hormone to the wound will help stimulate root development.
Next, moist sphagnum or peat moss should be wrapped around the wound, ensuring that it is at least 2 inches thick. This moss acts as a medium for the development of roots. Once the moss is in place, it should be covered with plastic and securely fastened with tape to maintain high humidity levels. It is vital to ensure that the moss remains consistently moist throughout the process.
After several weeks, roots will have developed and started to protrude out of the moss. At this point, the shoot can be cut off below the rooted end. The rooted shoot can then be planted in a pot or directly in the garden, allowing it to grow into a new magnolia tree. It is important to note that it may take two to three years for the newly propagated plant to start blooming.
Propagation By Seed
Propagation of magnolia trees can also be achieved through the use of seeds. The seeds can be collected from mature magnolia fruits, which should be allowed to fully ripen on the tree before harvesting. It is essential to keep in mind that magnolia seeds may have a natural germination inhibitor, so it is often recommended to stratify the seeds before sowing.
To stratify the seeds:
- Place them in a moist, sealed container.
- Store the container in the refrigerator for three to four months.
This pretreatment will help break the seed’s dormancy and promote germination. After stratification, the seeds can be sown in a pot or directly in the ground during the spring or early summer months.
Note: Magnolia trees grown from seed may not retain all the characteristics of the parent tree. Therefore, there may be variations in flower color, size, or other characteristics. However, this method of propagation allows for genetic diversity and the potential for new and unique magnolia hybrids to be developed.
Grafting In Winter
Grafting is a commonly used method to propagate magnolia trees. This technique involves physically joining two different plant parts to create a new, independent plant. For magnolias, grafting in winter is ideal, as it is best performed during the plant’s dormant period.
To begin the grafting process, select a rootstock, which is typically a strong, disease-resistant magnolia plant. Carefully choose the scion, or the desired magnolia variety, which will contribute to the upper part of the grafted tree, including its flowers and leaves.
Join the two plant parts by making a diagonal cut on both the rootstock and the scion. Fit the cuts together, ensuring that the cambium layers of both plants align. The cambium layer is responsible for the transportation of water, nutrients, and hormones within the plant. This alignment is crucial for the successful union of the two plant parts.
Once the cuts are properly joined, secure them using grafting tape or a grafting compound to prevent any movement or separation. Place the grafted plant in a protected environment with consistent moisture levels and temperature, allowing it to heal and form a strong bond. Over time, the rootstock and scion will grow together, creating a magnolia tree with desired characteristics.
Grafting In Spring
Grafting in spring is a viable option for propagating magnolia trees. This method is best performed when the plants are actively growing and displaying the first signs of new growth. The process is similar to grafting in winter, with the main difference being the timing.
The selection of the rootstock and scion remains the same, as does the process of joining the two plant parts. Cuts on the rootstock and scion should still be made diagonally and fitted together, ensuring alignment of the cambium layers.
- The grafted plant should be placed in a suitable environment where it can receive proper care and attention during the active growing season.
- Adequate moisture, sunlight, and protection from extreme weather conditions are important for the grafted plant.
- Regular monitoring of the graft union is essential to detect any signs of graft failure or infection.
“With proper care, the grafted magnolia tree should flourish and grow, eventually producing beautiful blooms in the years to come.”
Chip Budding In Summer
Chip budding is a grafting method commonly used for propagating magnolia trees during the summer months. This technique involves removing a small chip or bud from the desired magnolia scion and inserting it into the bark of a rootstock plant. Summer is an optimal time for chip budding as the plants are actively growing and displaying high levels of vascular activity.
To begin the chip budding process, a chip or bud should be selected from the desired magnolia scion. The chip should be taken from the current season’s growth and contain a dormant bud. The rootstock plant should be carefully prepared by making a vertical cut in the bark, creating a T-shaped incision.
The chip or bud should then be inserted into the incision, making sure it is firmly positioned and in close contact with the rootstock’s cambium layer. It is crucial to secure the chip or bud in place using grafting tape or other suitable materials. This will protect the graft site and ensure proper union between the scion and the rootstock.
After chip budding, it is essential to provide the grafted plant with adequate care and attention. The plant should be shielded from excessive heat and sunlight, reducing stress and promoting successful graft union. Regular monitoring of the graft site is crucial to identify any issues that may impede the growth and development of the budding magnolia tree. With proper care and attention, the grafted plant will grow into a beautiful magnolia tree, showcasing its unique characteristics and vibrant blooms.

Frequently Asked Questions
Can you grow a cutting from a magnolia tree?
Propagating magnolias from cuttings is a viable method to grow a new magnolia tree. By selecting a young and green branch, approximately 15 centimetres in length, you can easily find a suitable cutting. Once placed in slightly acidic potting soil and kept consistently moist, there is a good chance the cutting will take root and begin to grow, allowing you to successfully cultivate a new magnolia tree.
Can you root magnolia cuttings in water?
Yes, it is possible to root magnolia cuttings in water. To do so, select a couple of small, healthy branches and ensure that the cut ends are dipped in hot candle wax. This step helps to block the water supply and encourages the branch to focus its energy on rooting. Place the wax-covered branches in water and allow them to establish a few roots. Once the roots have developed, the magnolia cuttings can be transferred to a hole in the ground and planted as a new tree.
What time of year do you take cuttings from magnolia?
To successfully propagate magnolias, it is best to take softwood and greenwood cuttings during the spring season. While this method may have lower success rates, extra measures such as providing artificial light during the summer until leaf fall can help the cuttings develop sufficiently to endure the first winter. Once the cuttings have rooted, applying liquid feed and ensuring a frost-free environment during winter will further support their growth.
How do you propagate magnolia seeds?
To propagate magnolia seeds, start by placing them on a bed of damp peat and covering them with more moist material. Create 2 or 3 small holes in a plastic lid and place it securely on the container. Allow the container to sit in the refrigerator for a period of 3 to 5 months for stratification. Once the designated time has passed, take the seeds out of the refrigerator and plant them indoors.
