Bud Grafting Method
Bud grafting is one of the most popular and efficient vegetative propagation methods used in horticulture. Instead of using a whole twig or shoot, this method uses a single bud from a desired plant variety and inserts it onto a compatible rootstock. Because it requires less plant material and gives high success rates, bud grafting is widely practiced in fruit trees, ornamental plants, and nursery production.
This technique is especially useful for producing true-to-type plants, improving disease resistance, and increasing productivity. Let’s explore how bud grafting works, its types, advantages, and practical uses.

What Is Bud Grafting?
Bud grafting is a type of grafting in which a single vegetative bud (scion bud) from a superior plant is attached to the stem of another plant known as the rootstock. Once the bud unites with the rootstock, it grows and develops into a new shoot that carries all the genetic characteristics of the parent plant.
The success of bud grafting depends on proper cambium contact, correct timing, healthy plant material, and suitable environmental conditions.
Ideal Conditions for Bud Grafting
Bud grafting is usually performed when the bark of the rootstock can be easily lifted or “slips.” This typically occurs during the active growing season.
Best conditions include:
- Moderate temperature (20–30°C)
- High humidity
- Healthy and actively growing rootstock
- Mature but dormant buds for scion

Types of Bud Grafting Methods
1. T-Budding (Shield Budding)
This is the most commonly used bud grafting technique. A T-shaped cut is made on the rootstock bark, and a shield-shaped bud piece is inserted into it.
Commonly used for:
- Citrus
- Rose
- Peach
- Apple
2. Patch Budding
In this method, a rectangular patch of bark is removed from the rootstock and replaced with a matching bark patch containing a bud from the scion plant.
Suitable for plants with thick bark, such as mango and jackfruit.

3. Chip Budding
Chip budding does not require the bark to slip. A small chip of wood with a bud is removed from the scion and fitted into a similar cut on the rootstock.
Best for:
- Apple
- Pear
- Walnut
4. Ring Budding
A ring of bark containing a bud is removed from the scion and placed onto the rootstock after removing a similar ring.
This method is less common but useful in certain woody plants.
Step-by-Step Bud Grafting Procedure
- Selection of Rootstock: Choose a healthy, disease-free plant with good vigor.
- Selection of Bud: Select mature, well-developed buds from a high-quality mother plant.
- Making the Cut: Make a suitable cut on the rootstock depending on the chosen budding method.
- Inserting the Bud: Carefully place the bud into the cut, ensuring proper cambium contact.
- Tying: Secure the bud using grafting tape or polythene strip, leaving the bud exposed.
- Aftercare: Water regularly and protect from direct sunlight and pests.
After 2–4 weeks, successful bud union can be observed when the bud remains green and fresh.
Advantages of Bud Grafting
- Requires less scion material
- High success rate compared to other grafting methods
- Produces uniform and true-to-type plants
- Economical and time-saving
- Allows rapid multiplication of superior varieties
- Useful for changing plant varieties (top-working)
Limitations of Bud Grafting
- Requires skill and precision
- Depends heavily on proper timing
- Not suitable for all plant species
- Failure may occur under unfavorable weather conditions
Uses of Bud Grafting in Agriculture and Horticulture
Bud grafting is widely used in:
- Fruit tree propagation
- Nursery plant production
- Ornamental plant breeding
- Rejuvenation of old orchards
- Introducing improved varieties onto existing rootstocks
Crops like citrus, rose, peach, plum, apple, and mango benefit greatly from this technique.
Conclusion
Bud grafting is a highly effective and economical method of plant propagation that plays a crucial role in modern horticulture. By using a single bud, growers can produce high-quality plants with desirable traits such as better yield, disease resistance, and uniform growth. With proper practice, timing, and care, bud grafting can deliver excellent results for both commercial farmers and home gardeners.
Frequently Asked Questions (FAQ)
Q1. What is the best time for bud grafting?
The best time is during the active growing season when the bark slips easily, usually in spring or rainy season.
Q2. Which plants are suitable for bud grafting?
Fruit trees like citrus, apple, mango, peach, rose, and pear are commonly bud grafted.
Q3. How long does a bud take to grow after grafting?
A successful bud usually starts sprouting within 3–6 weeks after grafting.
Q4. Why is my bud graft failing?
Common reasons include poor cambium contact, dry buds, incorrect timing, or infection.
Q5. What is the main advantage of bud grafting over other grafting methods?
It uses minimal scion material and provides a high success rate with uniform plants.
Q6. Can beginners perform bud grafting?
Yes, with basic training and practice, beginners can successfully perform bud grafting.
