It has been known for decades that the Japanese grape berry also thrives in our latitudes. However, it is rarely found in home gardens. Perhaps the lack of knowledge about caring for them is a deterrent. In terms of cutting, we are now providing enlightenment.

Japanese grapes are usually trained on a trellis

Different rods

New shoots sprout each year on the Japanese grapeberry, while some of the existing shoots die off. So there is constant coming and going. Cutting helps to bring order to this clutter. What you should know:

  • Japanese grapes bear on last year's shoots
  • at the same time they sprout new shoots
  • these will only wear in the following year
  • rods that have already been harvested no longer bear fruit
  • they die off

education cut

Japanese grapevines form long shoots that bend downwards from a certain length under their own weight and lack of stability. To prevent this from happening, Japanese grapes are usually trained as a trellis.

The upbringing with five soil-borne shoots is ideal. The strongest are left and the weakest are cut off close to the ground.

Harvested shoots

Harvested canes that will never bear fruit are useless from the gardener's perspective. They can be cut down 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. Do the following with them in the fall:

  • select well-developed shoots
  • attach 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
  • or slightly above their trellis
  • Cut back side shoots to 10 cm

tips

If you bend a young tail so that it touches the ground, it will root at the point of contact. So you can easily multiply this berry variety.

taper cut

Even with the best care, an older Japanese grape can show signs of exhaustion. You can give it youthful vigor again by not sparing any rod when clipping. However, you will have to do without the red fruits for a year.

  • rejuvenate with radical cut
  • Cut off all shoots close to the ground
