If you want to propagate grapevines, this is basically not a problem. But in practice you have to be careful. There are laws that regulate the propagation of vines precisely.Grapevine cuttings
In Germany, grapevines may only be grafted on documents that are resistant to phylloxera. You should not plant unprocessed plants. And you should absolutely stick to that, because if you don't do that, you will have to face a very high penalty! In winegrowing areas, the planting of non-phylloxera-resistant plants can have fatal consequences. And you certainly don't want to be to blame for that.

New varieties are resistant to phylloxera
You can propagate grapevines either via offshoots or cuttings. On the other hand, you should not dare to multiply with seedlings, because they often split extremely. The propagation via cuttings is generally the best method, because special specialist companies use cuttings especially for this purpose, in order to get the problem with phylloxera under control.
For example, European and American varieties crossed. This is because the European vines do not show vine lice on the leaves, the American vines do not on the roots. Through targeted breeding, one would like to combine these two positive aspects and obtain varieties that are resistant to phylloxera. So the shoots of the European varieties are grafted onto the woody shoots of the American varieties.
Instructions for the propagation of vines by cuttings
➥ Step 1:
If you want to multiply grapevines via cuttings, this is an easy undertaking. You can get rain from existing ones or maybe you can get another variety for your garden from your neighbor or a friend. After cutting, simply cut off some young shoots that have about three to four knots.
2 Step 2:
Then cut the lower part of the sticks at an angle and dip these shoots briefly in special rooting powder.
3 Step 3:
Then plant the cuttings straight away. Best in a mixture of humus and sand (1: 1). Two knots must look out of the ground after insertion.
4 Step 4:
In the following days, you must now always make sure that you keep the soil nice and evenly moist. The cuttings should then take root very quickly.
Now you only have to wait until autumn. Then the roots should be well developed to implement the plants in the garden.
