How to graft grape vines? - Chef's Resource (2024)

Grafting grape vines is a fascinating technique that has been used for centuries to propagate and improve grape varieties. Whether you are a home gardener looking to expand your grape collection or a vineyard owner seeking to rejuvenate your vines, grafting can be a valuable skill to acquire. In this article, we will explore the process of grafting grape vines, step by step, and provide answers to some commonly asked questions about this ancient horticultural practice.

How to graft grape vines?

**Grafting grape vines is a method that involves joining a rootstock and a scion to create a new plant.**

1. Begin by selecting a healthy rootstock: Choose a rootstock that is resistant to diseases, adapts well to your climate, and matches the desired characteristics of the scion grape variety.
2. Prepare the scion: Select a scion from a desirable grape variety that you want to propagate. It should be a dormant, disease-free, and well-matured shoot from the previous season’s growth.
3. Make matching cuts: On both the rootstock and the scion, make smooth diagonal cuts with a sharp grafting knife, ensuring that the diameters of the cuts are the same.
4. Join the two parts: Connect the cut surfaces of the rootstock and the scion by placing them together, making sure that the cambium layers align. The cambium layer is a thin, greenish layer just beneath the bark that contains the growing tissue.
5. Secure the graft: Use grafting tape or budding rubbers to bind the joint tightly, leaving the buds and shoot tip exposed.
6. Provide protection: Seal the graft union with grafting wax or a grafting compound to prevent desiccation and infection.
7. Allow for growth: Place the grafted vines in a temperature- and humidity-controlled environment for a few weeks until the graft union has united, at which point they can be planted in the ground or pots.
