Grafting is a common horticultural practice that involves combining two plants to create one. It is particularly popular in orchards for creating new varieties of fruit trees. However, Japanese Maples are also frequently grafted. But why? Grafting ensures that the resulting tree is a true Japanese Maple and that it thrives. Starting a Japanese Maple tree from seed can be challenging, as there is no way to know what it will look like until it grows. Grafting offers a solution by allowing gardeners to obtain specific characteristics and create an exact replica of their desired Japanese Maple. In this article, Wildlife Informer explores the reasons behind grafting Japanese Maples and provides insights into the process.
Why Are Japanese Maples Grafted?
Grafting is a common practice in the world of gardening and horticulture, and Japanese Maples are no exception. This article will explore the reasons why Japanese Maples are often grafted, the advantages and disadvantages of grafting, the different types of grafting, the rootstock used for grafting Japanese Maples, the best time to graft, and more.
Grafting to create new varieties
Grafting is a technique used to create new varieties of plants by joining the tissues of two different plants together. This allows for the transfer of desirable characteristics from one plant to another. In the case of Japanese Maples, grafting is done to produce specific varieties with desired traits such as leaf color, leaf shape, and growth habit. By grafting, planters can ensure that the resulting tree will have the exact characteristics they desire.
Ensuring the trees are Japanese Maples
Another reason why Japanese Maples are grafted is to ensure that the trees are indeed Japanese Maples. When starting a tree from seed, it can be difficult to determine the exact species and characteristics of the tree until it fully grows. This uncertainty can be avoided by grafting, as the scion (the part of the graft that carries the desired characteristics) is taken from a known Japanese Maple tree, guaranteeing its identity.
Difficulty of growing Japanese Maples from seed
Japanese Maples can be challenging to grow from seed. Even with the right conditions, germination rates can be low, and the resulting trees may not develop the desired traits. Grafting provides a more efficient and reliable method of propagating Japanese Maples, ensuring a higher success rate and consistency in the characteristics of the tree.
Popular method for starting collections
Grafting is a popular method for starting collections of Japanese Maples. By grafting different varieties onto a single rootstock, collectors can have a diverse range of Japanese Maples in their collection without needing to grow each variety from seed individually. This allows for greater variety and diversity in a collection, as well as the ability to showcase specific traits and characteristics.
Do Japanese Maples Need To Be Grafted?
While it is possible to start Japanese Maples from seed, grafting is often preferred when it comes to obtaining specific varieties with desired characteristics. Starting from seed can result in unpredictable outcomes, as the resulting tree may not resemble the parent plant or have the desired traits. Nurseries often graft Japanese Maples to ensure consistency and accuracy in the trees they sell.
However, if you are not concerned about specific characteristics and are content with the unpredictability of starting from seed, then grafting may not be necessary. Starting Japanese Maples from seed can still be a rewarding and enjoyable experience, especially for hobbyists and gardening enthusiasts.
Difference between nursery plants and grafted plants
It is important to note that there is a difference between nursery plants and grafted plants. Most nursery Japanese Maples are grafted, meaning they have been created by joining the tissues of two different plants. These plants are specifically chosen for their desired traits, resulting in consistent characteristics in the trees sold by nurseries.
On the other hand, Japanese Maples grown from seed in nurseries may not exhibit the same characteristics as the parent plants. This is because the seeds are produced through natural pollination, resulting in genetic variation and unpredictable outcomes. So, if you want a Japanese Maple with specific characteristics, it is best to opt for a grafted plant from a reputable nursery.
High Graft Vs. Low Graft Japanese Maple
Once you have decided to graft a Japanese Maple, you will need to consider whether to do a high graft or a low graft. Each method has its advantages and disadvantages, so it is important to understand what each entails before making a decision.
Advantages of high grafts
High grafting refers to grafting the scion onto the rootstock at a higher point on the tree. This method has several advantages. Firstly, a high graft allows the tree to showcase its desired characteristics more quickly, as the scion is grafted closer to the top of the tree. This means that the desirable leaves, bark, and growth habit of the scion will be more prominent and noticeable sooner.
Secondly, high grafts tend to be visually more appealing, as the scion is grafted higher up on the rootstock. This creates a more aesthetically pleasing overall appearance, especially when the tree is in its mature form.
Disadvantages of high grafts
One disadvantage of high grafts is that they may be more susceptible to damage or stress, particularly during extreme weather conditions. The upper part of the tree is often more exposed to the elements, which can impact its health and overall growth.
Additionally, high grafts are typically more expensive than low grafts due to the extra care and attention required during the grafting process. This can be a consideration for those on a budget or looking for a more cost-effective option.
Advantages of low grafts
Low grafting involves grafting the scion onto the rootstock at a lower point on the tree. The main advantage of low grafts is their increased chances of survival. By grafting closer to the base of the tree, there is less risk of the scion being negatively impacted by environmental factors or damage. This can result in a stronger and more resilient tree in the long run.
Another advantage of low grafts is the element of surprise and anticipation. With a low grafted Japanese Maple, you will not know the exact form and characteristics of the tree until it fully grows. This can add an element of excitement and uniqueness to your gardening experience.
Disadvantages of low grafts
The main disadvantage of low grafts is the uncertainty of the tree’s final form and characteristics. While this can be exciting for some gardeners, it may not be desirable for those seeking specific traits and consistency in their trees. With a low graft, there is a higher chance of variation and unpredictability in the growth and appearance of the tree.
What Rootstock Is Used For Japanese Maple?
The rootstock used for grafting Japanese Maples is typically Acer Palmatum, a species known for its strong root system and compatibility with Japanese Maple scions. Acer Palmatum is a popular choice among grafters due to its ability to provide vigorous growth and support for the desired scion.
Commonly used Acer Palmatum rootstock
Acer Palmatum rootstock is commonly used because it is readily available and has proven to be successful in grafting Japanese Maples. This rootstock typically grows to a height of 18-22 inches, providing a suitable base for grafting the scion.
Other rootstock options for Japanese Maples
While Acer Palmatum is the most commonly used rootstock for grafting Japanese Maples, there are other options available. These include:
- Acer Japonicum: This rootstock is known for its beautiful fall color and can be used for grafting certain Japanese Maple varieties.

When is the Best Time to Graft Japanese Maples?
The optimal time to graft Japanese Maples is during the winter months, typically in January or February. Grafting during this period allows for successful healing and integration of the scion and rootstock.
Optimal grafting period in winter
Grafting in winter is advantageous for several reasons. Firstly, the dormant period of the tree allows for a better chance of successful grafting. The tree is not actively growing, which reduces the risk of stress and rejection of the scion.
Secondly, the cold temperatures of winter help slow down the healing process, giving the graft time to fuse properly. This increases the chances of a successful union between the scion and rootstock.
Ensuring a perfect looking tree in a reasonable amount of time
Grafting in winter also ensures that the resulting tree will have a more uniform and aesthetically pleasing appearance. By grafting during the dormant season, the scion and rootstock can heal and grow together, resulting in a seamless integration of the two. This contributes to a more visually appealing tree in a shorter amount of time.
It is important to note that grafting can be a delicate and precise procedure, so proper technique and attention to detail are essential for success. Following grafting best practices, such as maintaining proper temperature and humidity levels, will further increase the chances of a successful graft.
