Budding is a method of grafting where a single scion bud is united with the root stock. And T-budding is a method of budding where a “T” shaped cut is given on the rootstock and this is the reason for calling it T-budding. It is also known as shield budding because the scion used is shield shaped. This type of budding is suitable for the plants having thin skin. This is a suitable method for propagating rose. How to Propagate Roses by T budding are described as following-

Time of budding in rose
T-budding in Rose is done during the period from November to January because-
i) The plant at this time is inactive condition
ii) Well developed scion bud is available
Development of root stock
The rootstock is a plant on which scion is grafted and it is developed from stem cutting or layering. Generally, root-stock is developed from stem cutting of wild rose. Stem cuttings are placed in the nursery bed during the period from June to August. In the last week of September to 1st week of November, the old branches developed on the stock plants are removed to have a new branch in each stock plant. This new branch would be ready for budding.
Management of scion mother plant
Developed buds are available in the flowering shoots of a healthy scion mother plant. The scion mother plant is wintered in the last week of September or first week of October. New shoots develop with terminal flower buds. After opening and shedding of the flower the terminal bud(s) generally becomes ready for budding. Thus, it takes about 40 – 50 days for getting suitable scion buds.
Procedure of T-budding
Preparation of the root stock
A short horizontal cut of about 0.5cm is made on the inter-node of root stock. From the middle of the horizontal cut, a vertical cut of about 2-3cm is given. The vertical cut is then flipped carefully with the help of a knife’s terminal point.
Preparation of scion
The leaf near the selected bud is removed. The thorns are also removed. A shield shaped bark of 2cm long with a well-developed bud is collected from the scion mother plant. Then the shield-shaped scion is freed from the wood very carefully without doing any injury to the bark and bud.
Placement of scion
Holding the petiole with two fingers, the scion is inserted into the two flaps of the bark until the horizontal cuts on the stock and scion match together. The bud union is then tightly tied with a piece of polyethylene strip keeping the bud open.
The placed bud is observed carefully for about two weeks. All the branches develop from the root stock are removed. After the successful union, the above portion of the rootstock is cut off leaving 2-5cm above the union. Proper nursing is necessary for newly established Rose graft for its continued growth and should be kept free from insect and disease.
i) The scion bud should be cut smoothly and placed in the stock within 4-5 minutes without making any injury to the bud and the cambium.
ii) Any branch coming out from the root stock should immediately be removed from sight.
