Comment greffer en couronne un arbre fruitier

A tip for growing several varieties on the same tree: crown grafting fruit trees. Apple trees, pear trees, and all pome fruit trees can be crown grafted. Gardeners can remove the scion, gauge the graft while waiting for spring, and place the scion on the rootstock. Jean-Yves Meignen explains how to successfully crown graft a fruit tree. #grafting #orchard #fruit tree #gardening Scions, or young branches to be transplanted, should be removed in winter (January or early February) while they are dormant, preferably from the previous year's shoots. Grafting itself should never be done before March 15th to prevent the scions from starting to grow too early. To preserve them in good conditions until grafting time, they can either be partially buried in cold, shaded soil or wrapped in a damp cloth and stored in the refrigerator. When preparing trees for grafting, it is important to properly prune and carefully select the grafting location. Crown grafting allows you to change varieties onto an older tree, giving it a "second lease on life." Precise cuts must be made on both the grafts and the recipient tree, ensuring a proper fit to allow sap flow and scion growth. There are several methods for securing and protecting the scion in its new location, such as using cellophane or Teflon tape, and it is recommended to apply a healing sealant to the cuts to promote healing and prevent disease. After grafting, any new growth must be removed from under the scions so that all of the tree's energy is focused on them. It will take a few weeks to check if the graft has taken, and up to two months to confirm the success of the graft. Generally, immediate results should not be expected. For the first few years, it is important to let the grafts grow naturally in order to select the dominant branches. It can take up to five years after grafting for the tree to fully form and begin fruiting.
