Grafted olive tree

Grafted olive tree


The grafted olive tree allows this particular plant to see its chances of taking root grow and also guarantees a higher quality as regards the production of fruits. The olive tree is a plant that certainly does not prefer reproduction by seed, given that in all cases in which this solution is chosen, it is mostly wild varieties that have a very low productivity.

In any case, the multiplication by seed is exploited for the olive tree, which must always be accompanied by the rootstock. This explains why the olive tree graft is one of the most widespread systems that allow this particular plant to reproduce. It is a cultivation technique that is exploited on numerous occasions in the agricultural field, but also in gardens and nurseries, considering the great value of the plant from an ornamental point of view, especially in the last years of its life.

The grafting of the olive tree, in most cases, must be performed by people who have some experience in this field; in any case, it is good to underline that, with a little learning, even all garden care enthusiasts have the opportunity to carry out this operation.

Grafting by seed

The olive tree graft by seed uses one of the youngest olive trees that have grown through sowing as rootstock. On all these occasions, the seeds must be obtained by obtaining them from very particular varieties, such as the Cipressino, or the Canino, but also the Frantoio is excellent.

If this is not possible, a good alternative solution is represented by the seeds of the olive trees that develop inside the nurseries, but also those that refer to spontaneous species. As for the period in which to perform the withdrawal operation, it should correspond in most cases to the autumn season or the first part of the winter one. The seeds must be washed carefully and considerable attention must be paid to remove the fat well: at this point, there is the possibility of keeping them inside a completely dry and cool place.

During the month of August, or at the latest during that of September, of the year following the grafting by seed, the operation that corresponds to the sowing must be carried out. Thus, all the young olive seedlings will have their sprouts sprouting within a month and a half; subsequently, during the spring season, you will have to repot and the olive tree will have to be grafted only when the seedlings have a year and a half of life.

Grafting by cuttings

Grafting by cuttings allows you to take advantage of a combination of multiplication using cuttings and the traditional grafting system.

The cuttings can be considered plant components that are obtained with the aim of creating a new plant. This sampling can be carried out towards the roots or branches of a plant. The grafting of olive trees by cuttings can only be performed with species that have important complications for the development of the roots. The roots must be inserted, for a few minutes, inside a box that has a constant temperature with a good level of humidity and which contains a particular hormonal solution. The scions that will then derive from these cuttings are grafted using a particular rootstock that can count on a faster root development. In most cases, the grafting system that is practiced takes the name of common cleft, in which only a scion with three buds is used, which must be grafted with a rootstock that undergoes a horizontal cut.

Olive tree grafting: Other types of grafting

The olive tree is a plant that can also be grafted using other grafting systems, although the most common ones are always the crown and the common split.

The systems that represent an alternative to these two traditional techniques are, in most cases, grafting by approximation and what is called an eye or a shield.

As for the eye graft, the first thing to do is to take a circular component of wood and bark inside which there is a gem, which undergoes insertion inside the rootstock, which undergoes a horizontal cut and one vertically, in such a way as to form a sort of "T".

As regards the grafting by approximation, we must remember how we must proceed to link two branches of neighboring plants together, in such a way as to give contemporaneity to the development and allows a better growth of the new branches.

The operations concerning the grafting of the olive tree must be carried out, in most cases, during the spring season, i.e. when the plant is in suck and the circulation of the lymph is characterized by favoring a simpler detachment of the bark as well as allows a higher take root between the promissory parts of the graft and the rootstock.
