Detailed explanation-1: -Unlike budding, which can be performed before or during the growing season, most grafting is done during winter and early spring while both scion and rootstock are still dormant.

Detailed explanation-2: -Dormancy and Grafting When grafting woody plants, the scion wood must be dormant. This is because the scion has to live on its own until the graft union forms to unite it to the rootstock. A scion is a small piece of plant that has no roots, no way to feed itself.

Detailed explanation-3: -The best time for grafting is in the spring just as growth starts. When necessary, grafting can start several weeks before growth is expected and can continue a few weeks after growth has started, if you have dormant scion wood in storage and if weather is not exceptionally warm.

Detailed explanation-4: -Grafting is the insertion of a dormant short stick. (scion) of a desired plant into a compatible rootstock, tree or shrub.
