Graft without mastic: let's examine the composition of the putty for grafts so as to understand when it is not necessary to use it. Recipe to prepare a good DIY mastic.

Let's clarify one thing immediately: themastic for graftsorgrafting pasteit is always very useful but may be strictly necessary only in certain circumstances.

Paste or mastic for grafts, what is it

It is a dense substance that forms a protective film that isolates the affected part (graft or cut) from the external environment. Once dry, the film easily adapts to all plant movements without cracking, preserving its characteristics over time.

Mastic for grafts, composition

The composition of themastic for graftsvaries from manufacturer to manufacturer. There are, for example,masticswhich contain waxes. In this case we often talk aboutgrafting paste or waxes. These wax-based mastics must be preheated before application. Their use has been lost over time due to both lack of practicality and the risk of burning the scions.

Take for example one of the most used grafting mastics, used both to protect the surface of pruning cuts and to facilitate grafting.

Let's talk about the mastic for grafts "Arbokol pruning or grafting". The composition of this product sees the union of different synthetic resins which, solidifying in the air, give life to a hard but malleable plastic polymer. To the resin mix, many manufacturers (including Arbokol's) add cupric compounds to give the compound additional protective power. Mastics with added copper protect the plant from fungal attacks.

Homemade mastic

A good graft mastic can be made from vinyl glue. Homemade mastic, however, has some disadvantages because it is more difficult to apply.

The viscosity of themastics for graftsthat we find on the market is designed to facilitate application with the use of a brush. Homemade mastic may be too liquid and therefore more difficult to manage.

With thehomemade masticit is possible to reach the thickness of a few millimeters while with theputtybased on synthetic resins that we find on the market you can easily reach 12 - 25 mm and even the thinnest films (6 mm) have a very long life.

For a homemade mastic, useful for protecting plant wounds, you can choose a composition given by vinavil, Bordeaux mixture or copper sulphate and water in doses of 50, 3, 47%. This composition is useful in case of cutting but less useful to increase the chances of taking root of a graft.

For all information: homemade grafting mastic.

Graft without mastic

As anticipated in the introduction, it is possible make a graft without putty and immediately protect the graft with elastic insulating tape which, if necessary, must then be replaced.

The putty used on grafts, it not only protects wounds from fungal attacks, diseases and parasites, but also helps scion take root. How? The cut made for grafting is a "violence" for the plant which, spontaneously, will tend to produce a callus, removing the possibility of union with the scion. The mastic is applied to avoid the formation of the callus and assist in the taking root of the scion.

Theputtyit is only a help but it is possible to do agrafting without masticif the cut is done in a workmanlike manner!

The real secret of thesuccess of a graftdoes not lie in the use or not of theputtybut in the precision of the cut. Plus the scion and rootstock will be cut socompatibleand the higher the chances of engraftment.

Another focus, more relevant than the use of grafting mastic, lies in the correct choice of rootstock. Grafting must be performed on varieties resistant to the disease or on resistant and related species.
