oculating

Oculating refers to the process of joining two plants together so that they grow as one. This technique, a form of grafting, involves inserting a single bud or scion from one plant into an opening made in the bark of another plant, known as the rootstock. The goal is for the vascular tissues of the bud and rootstock to unite, allowing for the exchange of water and nutrients.

The process typically occurs during periods of active growth, when the cambium layer is most receptive to joining. The bud is carefully positioned to ensure good contact with the cambium of the rootstock. After insertion, the union is secured, often with grafting tape or wax, to protect it from drying out and to maintain close contact.

Occluding is commonly used in horticulture to propagate desirable varieties of fruit trees, roses, and ornamental plants. It allows for the combination of desirable traits, such as disease resistance from the rootstock and superior fruit or flower quality from the budded variety. This method also enables the rapid multiplication of plants that may be difficult to root from cuttings or are slow to grow from seed. The success of occluding depends on factors like the compatibility between the scion and rootstock, the skill of the grafter, and appropriate environmental conditions.
