How to Graft Citrus Trees: Unlocking Fruitful Possibilities
How to Graft Citrus Trees?
To graft citrus trees, the preferred method is budding.
This involves removing a bud and some bark from the desired variety and inserting it beneath the bark of a rootstock tree.
The ‘T’ budding procedure is recommended for inexperienced growers.
To graft, make a vertical cut through the bark of the rootstock and a horizontal cut at the bottom to form an upside down ‘T’.
Then, remove a budded twig and insert the bud under the flaps of the ‘T’ cut.
Wrap the graft with budding tape and remove the wraps within 30 days.
A green, healthy-looking bud indicates a successful graft.
To promote growth, cut a portion of the rootstock and push it to the ground.
Trim the rootstock above the bud once it grows 3 to 4 inches.
Lastly, remove rootstock buds to prevent competition.

Did You Know?
1. Grafting citrus trees allows for the fusion of different citrus varieties on a single tree, such as lemons, oranges, and grapefruits, resulting in an array of fruits on one plant.
2. Citrus trees can be grafted onto different rootstocks, which affects their tolerance to different soil conditions, disease resistance, and overall productivity.
3. Did you know that the first successful graft of a citrus tree occurred around 2,000 years ago in ancient China? This breakthrough marked the beginning of a long history of citrus tree cultivation and grafting techniques.
4. The technique of grafting citrus trees is commonly used to propagate rare or unique citrus varieties that cannot be easily reproduced through seeds. This allows farmers and enthusiasts to preserve heirloom varieties that might otherwise be lost.
5. In addition to preserving unique characteristics and ensuring consistent fruit quality, grafting also enables citrus trees to mature faster and bear fruits earlier than if they were grown from seeds alone. This is advantageous for commercial growers seeking to bring their products to market more quickly.
Introduction To Budding Method For Grafting Citrus Trees
Grafting is a vital technique in horticulture, specifically for propagating citrus trees. Budding is commonly preferred among the available methods.
Budding entails taking a bud and some bark, known as budwood, from the desired variety (known as the scion), and inserting it beneath the bark of a host tree (known as the rootstock). Through this process, the scion merges with the rootstock, giving rise to a new tree that produces the desired variety of citrus fruits.

“Grafting is not only important for horticulture, but it is also a preferred method to propagate citrus trees. By inserting budwood, which consists of a bud and some bark from the desired variety (scion), beneath the bark of a host tree (rootstock), the scion and rootstock merge, giving rise to a new tree that bears the desired variety of citrus fruits.”
Importance Of The ‘T’ Budding Procedure For Inexperienced Growers
For inexperienced citrus tree growers, the ‘T’ budding procedure is highly recommended. This method is relatively simple and increases the chances of successful grafting. The ‘T’ budding procedure involves:
- Making a one-inch vertical cut through the bark of the rootstock
- Making a horizontal cut at the bottom, forming an upside-down ‘T’ shape
- Providing an opening in which the bud from the scion is inserted.
By following this procedure, novice growers can have a higher success rate when grafting citrus trees.
Restrictions On Budwood Importation And Disease Concerns
It is important to be aware that some states have regulations prohibiting the importation of budwood due to disease concerns. These measures aim to prevent the spread of potential pathogens that could harm the local citrus industry. Growers should familiarize themselves with their region’s regulations and consider using locally sourced budwood to avoid the risk of introducing harmful diseases to their citrus orchards. By adhering to these restrictions, growers can help maintain the health of citrus trees and protect their investment.

The Best Time To Collect And Store Budwood
Budwood collection is typically done between April and November, as this is the period when the twigs have begun to harden. It is important to select healthy branches with mature buds from the desired variety for optimal grafting success.
After collection, it is essential to store the budwood properly to maintain its viability. The recommended method is to place the budwood in a sealed polyethylene bag and store it in the refrigerator’s vegetable crisper.
It is crucial to use the stored buds within three months to ensure their viability for successful grafting.

Step-By-Step Guide To Grafting Citrus Trees Using Budding Method
To graft citrus trees using the budding method, follow these step-by-step instructions:
- Select a young citrus tree as the rootstock.
- Make a one-inch vertical cut through the bark of the rootstock and a horizontal cut at the bottom to form an upside-down ‘T’ shape.
- Carefully remove a bud and a one-inch sliver of wood and bark from a budded twig of the desired variety.
- Insert the bud under the flaps of the ‘T’ cut on the rootstock, ensuring that the budwood is in direct contact with the cambium layer.
- Use budding tape to wrap the graft, ensuring that it is secure but not too tight.
- Keep the wrapped graft protected from excessive sunlight and wind.
- After approximately 30 days, carefully remove the wraps to allow for new growth.
-
Monitor the bud closely; a green, healthy-looking bud indicates a successful graft.

Post-Grafting Care Tips For Successful Growth Of Citrus Trees
To promote the successful growth of the newly grafted citrus tree, proper post-grafting care is crucial. One effective technique is to stimulate growth by cutting 2/3 of the way through the rootstock and pushing it slightly to the ground. This process, known as bending, encourages the growth of the scion. After the bud grows 3 to 4 inches, it is essential to cut the top of the rootstock approximately one inch above the bud. Additionally, to prevent competition, any buds that grow on the rootstock should be promptly removed. By following these post-grafting care tips, growers can ensure the healthy development of their citrus trees and unlock a fruitful future.
Frequently Asked Questions
What is the best method of grafting citrus trees?
One method of grafting citrus trees is through whip and tongue grafting. This technique involves cutting a diagonal, wedge-shaped cut on both the scion and rootstock, and then joining the two pieces together like puzzle pieces. The whip and tongue method provides a secure and tight union between the scion and rootstock, ensuring successful grafting and healthy tree development.
Another method that has shown success in grafting citrus trees is side-veneer grafting. This technique involves making a long, vertical cut on the side of the rootstock and inserting a scion into the incision. The scion should have a matching diagonal cut to fit into the rootstock securely. Side-veneer grafting is a relatively easy and effective method for grafting citrus trees, especially for those with less experience in grafting techniques. Both methods result in the combination of desirable characteristics from the scion and healthy rootstock, leading to the growth of a productive citrus tree.
When can I graft citrus?
Grafting citrus is best done in late winter to spring when the bark slips easily from the cut surface. It is important to make a fresh cut on the limb right before grafting. This timing ensures the success of the graft by allowing the new plant to quickly establish itself and grow vigorously.
How is a lemon tree grafted?
Lemon trees are grafted through a process called bud grafting. This method involves carefully extracting a small bud from a high-quality mother tree and joining it beneath the bark of a young seedling, known as the rootstock. By doing so, the roots of the new tree will originate from the rootstock, while the stem, leaves, and fruit will derive from the mother tree. This technique allows for the combination of desirable traits from both tree types, creating a unique lemon tree with enhanced qualities.
What rootstock is used for grafting citrus?
The rootstock commonly used for grafting citrus is typically the Trifoliata orange, also known as sour orange. The graft union, identifiable as a swollen point or crook in the lower part of the trunk, serves as a key feature to locate when purchasing a young citrus tree.
