There are numerous methods of grafting plants. They are whip grafting, whip and tongue grafting, side grafting, cleft grafting, bark grafting, attached scion grafting, root grafting, micro grafting and bridge grafting. These methods adopted vary according to the kind of plant, the age of plant and the season of grafting (Etc.)
This method now has been proved to be an important method of vegetative propagation of mango. Common varieties like Karthacolumban, Willard, Vellaikolomban and Malwana are graft using this method. In this, 14 days (2 weeks) after germination the seedling rootstock is grafted with the suitable scion. The grafting is usually done on the epicotyl portion of the seedling. The cleft method has been found almost easy and successful.
- The mango seeds are plant on the sand bed.
- These seedlings are use as rootstock.
- After 14 days the seedlings are uproot carefully and re-plant on polybags. The polybags are filled with topsoil and coco dust mixture.
- Using two opposing upward strokes of the grafting knife sever the top from the rootstock. The resulting cut should resemble an inverted (V).
- Surface of the cuts ranging from 1/2 to 1 inch long.
- Now reverse the technique to prepare the base of the scion.
- These cuts on the rootstock and scion must be the same length and have the same slope so that a maximum amount of cambial tissue will make contact when the two halves are joined.
- Then place the V-notched scion onto the saddle of the rootstock. If rootstock and scion are the same diameter, cambial alignment is easier; otherwise adjust as needed.
- Wrap the graft with a strip of polythene, then cover the scion and rootstock using small polythene bag.

Good post. Keep it up!
Sameera I am very interested in this. Can I contact you?
nice. have any data on success rate and ageing of rootstock and scion?
