Upbringing
Japanese grapevines form long shoots that, from a certain length, bend down under their own weight and due to a lack of stability. To prevent this from happening, Japanese grapes are usually raised as a trellis.
Upbringing with five native shoots is ideal. The strongest are left and the weakest cut off near the ground.
Harvested shoots
Harvested rods that will never bear again are useless from the gardener's point of view. They can be cut off close to the ground after the last harvest, around late autumn. In mild regions of the country, you can easily reach for scissors at this time. In rough locations, on the other hand, it is advisable to wait until spring.
Young shoots
Young shoots are the future because they will bear the next harvest. You do the following with them in autumn:
- choose well-developed shoots
- tie to the scaffolding
- Cut off weak shoots close to the ground
- no more than 10 shoots should remain per meter
In spring, in March or April, further pruning measures are necessary:
- Shorten rods to 2-3 m
- respectively. slightly above their climbing aid
- Cut the side shoots back to 10 cm
Tips

- rejuvenate with radical cut
- cut off all shoots close to the ground
