When you combine plants, it’s most commonly referred to as grafting or budding. These horticultural techniques involve joining parts of two or more plants so they grow as a single plant. Grafting is a vital practice for propagating many fruit trees and ornamental shrubs.

Understanding Plant Combinations: Grafting and Budding Explained

Have you ever wondered what happens when you join two plants together? The process is a fascinating aspect of horticulture, allowing growers to combine desirable traits from different plants. The two primary methods for achieving this are grafting and budding.

What is Grafting?

Grafting is a technique where tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion, while the lower part is called the rootstock. This method is widely used for propagating plants that don’t grow true from seed or to introduce disease resistance.

For example, many apple varieties are propagated through grafting. The desired apple variety (the scion) is grafted onto a rootstock that provides specific characteristics like dwarfing or disease resistance. This ensures that the fruit produced is identical to the parent scion.

What is Budding?

Budding is a type of grafting where the scion is reduced to a single bud. This bud, along with a small portion of the bark and cambium, is inserted under the bark of the rootstock. It’s often preferred for certain plants, especially roses and stone fruits, due to its efficiency.

A common application of budding is in the production of rose bushes. A bud from a desirable rose variety is budded onto the rootstock of a hardy rose species. This allows for the propagation of a specific flower color or fragrance onto a robust and adaptable root system.

Why Combine Plants? The Benefits of Grafting and Budding

Combining plants through grafting and budding offers several significant advantages for both commercial growers and home gardeners. These techniques allow for the creation of plants with enhanced characteristics that might not be achievable through natural reproduction.

Enhancing Desirable Traits

One of the main reasons for combining plants is to leverage desirable traits. For instance, you might graft a fruit variety known for its excellent flavor onto a rootstock that provides vigor and disease resistance. This results in a plant that produces superior fruit on a healthy, long-lived tree.

Accelerating Fruiting and Flowering

Grafted plants often begin to produce fruit or flowers much sooner than their seed-grown counterparts. The scion is typically taken from a mature plant, meaning it already has the biological capacity to reproduce. This can shorten the time to harvest for fruit trees significantly.

Repairing Damaged Plants

Grafting can also be used as a rescue technique for damaged trees. If a tree has suffered significant damage to its trunk, grafting can be used to bridge the gap, allowing nutrients and water to flow past the damaged area and saving the tree.

Creating Novelty Plants

Horticulturists also use grafting to create novelty plants, such as trees with multiple varieties of fruit on the same specimen (a "fruit salad tree") or ornamental plants with unique color patterns. This showcases the versatility of plant combination techniques.

Common Grafting and Budding Techniques

There are numerous methods for grafting and budding, each suited to different plant types and situations. Understanding these techniques can help you appreciate the skill involved in plant propagation.

Whip and Tongue Graft

This is a common technique for young trees and shrubs. It involves making diagonal cuts on both the scion and rootstock that interlock, creating a strong union. It requires precise cuts for successful adhesion of the cambium layers.

Cleft Graft

The cleft graft is often used to top-work established trees. The rootstock is split down the center, and wedge-shaped scions are inserted into the split. This method is effective for changing the variety of an existing fruit tree.

Bud Grafting (T-Budding)

As mentioned earlier, T-budding involves inserting a single bud into a T-shaped cut in the bark of the rootstock. This is a very efficient method, especially for deciduous trees and roses.

Practical Examples of Plant Combinations

The application of grafting and budding is widespread across agriculture and horticulture. Here are a few practical examples:

• Fruit Trees: Apples, pears, cherries, peaches, and citrus are almost exclusively propagated by grafting or budding to ensure consistent fruit quality and to control tree size.
• Roses: Most modern rose bushes are budded onto hardy rootstock for improved vigor and disease resistance.
• Grapes: Grapevines are often grafted to combine desirable grape varieties with rootstock resistant to soil-borne pests and diseases like phylloxera.
• Ornamental Trees and Shrubs: Many landscape plants, such as Japanese maples and lilacs, are grafted to achieve specific growth habits or to propagate rare cultivars.

People Also Ask

### What do you call joining two plants together?

Joining two plants together is generally called grafting. It’s a horticultural technique where the tissues of one plant are joined to those of another so they can grow as a single plant. Budding is a specific type of grafting that uses a single bud as the scion.

### What is the difference between grafting and budding?

The main difference lies in the size of the scion used. Grafting typically involves a piece of stem with multiple buds, while budding uses only a single bud. Budding is often more efficient for certain plants and can be done when sap flow is high.

### Can you graft any two plants together?

No, you generally cannot graft any two plants together. For successful grafting, the plants must be closely related, usually within the same family or genus. For example, you can graft different varieties of apples onto apple rootstock, but you cannot graft an apple onto an oak tree.

### What is the purpose of rootstock in grafting?

The rootstock provides the root system for the grafted plant. Its purpose is to supply water and nutrients, influence the size and vigor of the scion, improve disease and pest resistance, and adapt the plant to specific soil conditions.

Conclusion: The Art and Science of Plant Combinations

Understanding what it’s called when you combine plants, primarily grafting and budding, reveals a sophisticated horticultural practice. These techniques are not just about joining plants; they are about optimizing plant performance, ensuring true-to-type propagation, and creating plants with enhanced resilience and productivity.

Whether you’re a gardener looking to grow your favorite apple variety or a professional seeking to improve crop yields, the principles of plant combination offer powerful solutions.
