Also known as "Äugeln", this is a very old form of grafting, already known in antiquity, which is derived from the Latin term "oculus" (eye). It is mainly used for roses and fruit trees, rarely also for vines. An eye (bud) is cut flat out of the scion at a length of about one to two centimetres for roses and about three to four centimetres for fruit. On the rootstock (root part) a T-shaped cut is made with a very sharp knife (hence T-oculation) so that the bark can be carefully loosened to the left and right. The previously cut out eye is now inserted into the slit and the bark folded back again.
As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.Hans-Georg Schwarz
