Kiwi Grafting Techniques for Professionals
Grafting Kiwifruit: A Key Technique for Professional Kiwi Growers
Grafting is an essential technique for professional kiwi growers looking to optimize their production. It is a vegetative propagation method that combines the characteristics of a quality scion with the advantages of a robust rootstock well-adapted to local conditions. By combining these two elements, kiwi growers can improve their plants' resistance to disease, increase yields, and ensure optimal fruit quality.
In France, where kiwi is a flagship crop, specific grafting techniques have been developed to meet the needs of professionals. Bud grafting and herbaceous grafting are among the most commonly used methods due to their effectiveness and simplicity.
What is the Kiwi Transplant?
Kiwi grafting is based on a simple principle: implanting a scion (the part of the plant that will produce fruit) onto a rootstock (the underground part that provides nutrition). The choice of rootstock is strategic, as it must offer good disease resistance, tolerance to environmental conditions, and optimal compatibility with the scion.
The main objective of this technique is to optimize production in terms of quality and quantity, while adapting the crop to local constraints, such as climate or soil characteristics.
The Main Techniques for Grafting Kiwis
Cleft Grafting
-
Steps:
- Rootstock preparation: Cut to 10-15 cm from the ground and make a central slit.
- Graft preparation: Cut it in a double bevel to form a fine point.
- Insertion: Insert the graft into the cleft, aligning the cambiums.
- Ligation: Secure the graft with a raffia or biodegradable plastic tie, then apply healing mastic.
- Advantages: Simple to make, suitable for woody grafts.
Shield Graft

Steps:
- Taking the graft: Cut a bud with a thin layer of bark.
- Rootstock preparation: Make a T-shaped incision in the bark.

- Binding: Secure with an elastic band without blocking bud growth.
- Advantages: Minimally invasive, promotes good contact between cambiums.
Herbaceous Grafting
-
Steps:
- Taking the graft: Take a graft from a well-seasoned vine.
