How do you graft a wisteria?

To graft a wisteria, start by selecting a healthy rootstock and a scion from a desirable wisteria variety. Make a diagonal cut on the scion and a corresponding cut on the rootstock to create a matching surface for joining. Secure the scion to the rootstock using grafting tape or parafilm, ensuring good contact between the cambium layers. Finally, keep the grafted area moist and provide appropriate care until the graft has successfully taken and new growth appears.
