kloofgrafting

Kloofgrafting is a horticultural technique used to join two plants, typically a scion (a cutting or bud from one plant) with a rootstock (the lower part of another plant). This method is employed to propagate desirable cultivars that may not root easily on their own, or to combine the desirable traits of two different plants, such as disease resistance of the rootstock with the fruit quality of the scion. The term "kloof" originates from the Afrikaans word for "ravine" or "gorge," which likely refers to the V-shaped cut made in the rootstock to receive the scion, creating a snug fit.

The process involves making a precise incision in the rootstock, often a wedge or a tongue-and-groove cut. A similarly shaped cut is then made on the scion, ensuring that the cambium layers (the actively growing tissues just beneath the bark) of both the rootstock and the scion align as closely as possible. This alignment is crucial for the successful vascular connection that will allow water and nutrients to flow between the two parts. Once fitted together, the graft union is securely wrapped with grafting tape or twine to hold the pieces firmly in place and prevent drying out.

Kloofgrafting is commonly used for fruit trees, roses, and other woody ornamentals. Its success depends on several factors, including the compatibility of the species being grafted, the health of both the scion and rootstock, the timing of the graft (usually when both are dormant or in active growth), and the skill of the grafter in making clean, precise cuts and ensuring good cambium contact. Proper aftercare, such as maintaining moisture and protecting the graft union from damage, is also vital for healing and establishment.
