Splice Grafting Propagation

Splice grafting is a propagation technique that involves joining two plant parts together to form a successful graft union. It is a common method used to combine the desirable traits of two plants into a single plant. This method is often used on fruit trees, ornamental trees, and woody shrubs.

Step 1 - Choose a suitable rootstock (the lower part of the graft that will provide the root system and support for the grafted plant) and a scion (the upper part of the graft that carries the desired characteristics, such as specific fruit varieties or desirable ornamental traits.)

Step 2 - Make a diagonal cut near the base of the rootstock and a corresponding diagonal cut at the bottom of the scion. The cuts should match and fit together as closely as possible.

Step 3 - Place the cut surfaces of the rootstock and scion together, aligning the cambium layers. The cambium is a thin layer of tissue between bark and wood that grows new cells. It is important to ensure a tight and secure fit between the two parts.

Step 4 - Wrap the graft union with grafting tape or a grafting clip to hold the rootstock and scion firmly together. This helps align and prevent movement. Apply a grafting compound or sealant over the graft union to protect it from moisture loss and infection.

Step 5 - Place the grafted plant in a suitable environment, such as a greenhouse or a protected area, where it can receive appropriate light, temperature, and humidity. Maintain consistent moisture levels to support healing and growth.

Step 6 - Regularly monitor the grafted plant for signs of successful unions, such as new growth and leaf development. You should remove any competing growth below the graft union in order to direct energy toward the scion. Provide ongoing care, including watering, fertilizing, and protecting the grafted plant from pests and diseases.
