Types of Grafting Techniques
Whip and Tongue Grafting
Whip and tongue grafting is a common technique in horticulture that joins two plant parts together. It involves cutting matching diagonal incisions into the scion and Rootstock, creating a tongue-like extension on each. The scion and Rootstock are then joined by inserting the tongues together, creating a secure connection. This grafting technique suits various plant types, including fruit trees, woody plants, and flowering plants.
Cleft Grafting
Cleft grafting is a grafting technique used when the diameter of the scion is smaller than the Rootstock. It involves making a vertical split in the Rootstock and inserting the scion into the aperture. This technique is beneficial when grafting older trees or working with uneven sizes of scions and rootstocks.
Bark Grafting
Bark grafting is commonly used on trees with thick bark, such as apples, pears, and citrus. It involves making a vertical cut in the Rootstock’s bark and inserting the scion into the exposed cambium layer. The bark is then tightly wrapped to secure the graft. This method allows for efficient nutrient transport between the scion and Rootstock.
Side Grafting
Side grafting, also known as approach grafting, is a technique used when there are no suitable branches for grafting on the Rootstock. It involves making a diagonal cut on the Rootstock’s side and a matching cut on the scion. The two cuts are then carefully fitted together and secured with grafting tape. This technique is beneficial for older trees with limited suitable grafting sites.
Choosing the Right Rootstock
Understanding Compatibility
When selecting a rootstock for grafting, compatibility between the scion and the Rootstock must be considered. Compatibility refers to the ability of the scion and Rootstock to form a successful union and grow together harmoniously. Choosing a rootstock that is genetically similar to the scion is crucial, as this increases the chances of a successful graft.
Considering Plant Health and Vigor
Plant health and vigor play a significant role in grafting success. It is advisable to choose a healthy Rootstock free of diseases or pests. A weak or diseased rootstock may hinder the growth and development of the grafted scion. Additionally, selecting a rootstock with good vigor will ensure optimum nutrient uptake and overall plant vitality.
Evaluating the Growth Habit
The growth habit of the Rootstock is another essential factor to consider when choosing a suitable rootstock for grafting. Different rootstocks have varying growth habits, such as dwarfing, semi-dwarfing, or standard. It is essential to select a rootstock with a growth habit that matches the desired outcome for the grafted plant. For example, a dwarfing rootstock would be ideal for a smaller tree.
Preparing the Scion and Rootstock
Selecting Healthy Plant Material
Before grafting, it is crucial to carefully select healthy plant material for both the scion and the Rootstock. Look for plants free from diseases, pests, and physical damage. Healthy plant material provides the best chances for successful grafting and ensures the long-term health of the grafted plant.
Proper Scion and Rootstock Size
The size of the scion and Rootstock is essential for successful grafting. The scion should align closely with the diameter of the Rootstock to ensure a good fit and proper cambium contact. A size mismatch can lead to a weak graft union and reduced chances of success. It is important to note that the diameter of the scion should be slightly smaller than the Rootstock to allow for proper healing and growth.
Making Clean and Precise Cuts
When preparing the scion and Rootstock, they make clean and precise cuts, such as Rootstocktial. Jagged or uneven cuts can interfere with the successful union of the graft. Use a sharp, sterilized grafting knife or pruners to ensure clean cuts. Cutting at a slight angle or bevel can help increase the contact area between the scion and Rootstock, enhancing the chances of a suRootstockgraft.

Whip and tongue grafting is often used for flowering plants, such as roses or camellias. The scion and Rootstock should be healthy, compatible, and of a similar size. Proper care should be taken during grafting to prevent damage to delicate plant tissues.
Budding Techniques
T-Budding
T-budding is a common budding technique used on herbaceous plants and fruit trees. It involves making a T-shaped incision on the Rootstock’s bark, removing a bud from the cushion, and inserting it under the Rootstock’s bark. T-budding is an effectRootstock’sfor quickly propagating a large number of plants.
Chip Budding
Chip budding is a budding technique commonly used for fruit trees. It involves removing a small chip from the desired scion and inserting it into a matching chip-shaped incision on the Rootstock. Chip budding provides a large rootstock contact area, allowing for a greater chance of successful grafting.
Patch Budding
Patch budding is used to graft young rootstocks or smaller scion materials. It involves removing a patch from the Rootstock’s bark, inserting a matching pRootstock’s piece from the desired scion, and securing it with grafting tape. Patch budding is advantageous for propagating plants with limited scion material.
Inverted T-Budding
