Propagation of rose by T budding in 2020
Propagation of rose by T budding is a common technique in rose garden. Budding is a method of vegetative propagation in which a single but is united with another plant. budding utilizes only one bud and a small section of bark with or without wood.

Objectives of budding
- Obtaining benefits of certain promising rootstocks
- changing inferior varieties to Superior variety
- Helping pollination
- Induction of flowering is young seedlings
- Repairing of damaged parts of trees
- Studying the presence of virus disease
- Produce Novelty plants
Advantages of budding
- Deserved variety can be developed
- It is a rapid method of propagation
- Within 2 weeks Sakar confirmation can be gained
- This operation is comparatively less time consuming and low cost
- Many scions can we can get from the mother plant
- Transplantation of the scion is very easy
Disadvantages of budding
- Required skilled person
- It is not possible thick bark plant
- As the sign is so small it becomes complex suitable scion are not available all times
- This operation cannot be done every time
Propagation of rose by T budding
This method is known by both names "T-bud" designations arising from the t-like appearance of the cut in the stock. Whereas the shield bud name is derived from the shield-like appearance of the bud piece when it's ready for insertion in the bark.
Budding is the most common method of budding is widely used by nurserymen in propagating nursery stock of most fruit tree species, roses, and many ornamental shrubs. its use is generally limited to stocks which are ¼ to 1 in diameter with fairly thin bark and which are actively growing so that the bark will separate readily from the wood.
T-Budding in rose:
Rose may be propagated by t budding. in this method rootstock of about six months of age may be selected.
Time of budding
Most of the time for budding when the stock plant is in active growth and cambial cells are actively dividing so that the bark separates easily from the wood. it is also necessary that well-developed buds of desired variety be available at the same time. T budding in rose is done during the period from November to January because the plant at this time is inactive condition and well developed on a bird is available.
Section of scion
- It should be about to sprout
- It should be taken from current year growth
- Rootstock plant
- Budding knife
- Polythene strip or tape
One-year-old rootstock is used in budding the thickness of the stock varies from 0.62 cm to 25 cm having thin and readily separating bark. The bark is placed into the stock about 5 to 25 cm about the soil level on a smooth clean surface between the nodes of rootstocks. if the budding is done during the hotter months it is advisable to place the bud on the north-east side of the rootstock which will protect the bird from excessive exposure to the sun.
1st step (Preparing of rootstock)
First, a vertical cut about 2.5 cm long is made on the selected portion of the rootstock with the help of a budding knife. Then a horizontal cut across the top at the right angle to the first cut is made. then the cut resembles a "T". The spatula portion. the budding knife is then inserted into the incision and the two flaps of the bark are then loosened and slightly to receive the bud.
2nd step (Preparing of Scion)
Bud is removed from the bud stick by cutting shallowly about 6.2 mm below a mature bud and continuing up to about 2.5 cm above the bud. The bird should not be too thin or too thick. The wood is removed by budding the bark outwards and flicking it out.
3rd step (Insertion of the scion into rootstock)
The next step is the insertion of the shield piece containing the bud into the incision of stock. Using the leaf stalk as a handle the bird is slipped into the T cut on stock, and the tail forms off by cutting it horizontally along the top of the cut. The Shield should be placed and well covered by two flaps of bark keeping the bud exposed.
4th step (Wrapping the bud)
The next step is wrapping the bud with the stock so as to press the shield firmly against the gate string, rubber band, and wax budding tape. During wrapping, care is taken so that the bud remains exposed but all cut portions are fully covered
After three to four weeks or more when the bird unites the stock the tape is removed when the bud starts growing the top of the rootstock is cut above 25 mm above the bud.
Limits of budding
The main limitation of budding is the incompatibility between plants. Besides, they are confined to plants that have a continuous layer of vascular cambium between xylem and phloem.
