Grafting is the process of joining two trees together, allowing them to grow as one. It is a technique commonly used in gardening and horticulture to propagate desirable traits, such as specific fruit varieties or disease resistance, onto rootstock that provides strong growth and support.
When we talk about grafting, it typically involves two trees of the same or closely related species or genera. However, there are instances where the appearance of grafting can be observed between two trees that are physically touching, rubbing, intertwined, or entangled. This phenomenon is not true grafting, but it can create a similar visual effect.
When two trees are physically touching or rubbing against each other, their branches may become intertwined over time. This can result in the trees sharing nutrients and water through the point of contact, creating a bond that resembles grafting. In some cases, the bark of the trees may even fuse together, further enhancing the appearance of grafting.
I have personally witnessed such instances in my own garden. Two trees, a maple and a birch, were growing in close proximity to each other. Over the years, their branches grew intertwined, creating a beautiful and unique visual effect. While it wasn’t true grafting, it definitely gave the impression of two trees merging into one.
It’s important to note that this natural phenomenon is different from deliberate grafting carried out by gardeners and horticulturists. In intentional grafting, specific techniques are employed to ensure a successful union between the scion (the desired plant part) and the rootstock. This involves making precise cuts, aligning the vascular tissues, and securing the graft with grafting tape or other materials.
In contrast, the appearance of grafting through physical contact between trees is a result of natural growth and intertwining. It is not a deliberate technique employed by humans but rather a fascinating occurrence in nature.
To summarize, grafting typically involves deliberate joining of two trees of the same or closely related species or genera. However, trees that are physically touching, rubbing, intertwined, or entangled can give the appearance of grafting, even though it is not a deliberate act. This natural phenomenon creates a visually striking effect that is intriguing to observe.
