Transcript

  • 1. How to Prune Grapevines Part Two
  • 2. Recap…….
    • Count nodes contain the buds that are deliberately left at pruning
    • They produce count shoots which will produce the flowers which become the fruit
    • At the same time as flowering the new buds are forming in the shoot
    • Shoots become canes when they turn brown
    • Pruning is a matter of leaving count nodes
  • 3. Cane Pruning
    • Canes from the previous season are rapped around fruiting wires and then tied down at the ends
  • 4. Cane Pruning
    • There are many different versions and types of cane pruning
  • 5. 4 canes
  • 6. 4 canes
  • 7. Or two canes This is the same vine but later on
  • 8. Cane Pruning Technique
    • Canes are between 8-20 count nodes
    • Spurs are retained to produce replacement canes for the following year
  • 9. Cane Pruning Technique
    • Vines are head trained
      • canes and spurs are selected from the head
    • Vines may be unilateral or bilateral
      • Canes run one way or both ways
  • 10. There are three stages
    • Stage One
    • Select the canes and spurs that are wanted for the coming season
      • and cut off the rest
    • Spurs are retained to provide the canes for next season
  • 11.

    • Make sure you DO NOT select canes older than last seasons
    • These will not contain buds that are fruitful
  • 13. These were last years canes
  • 14. These were last years canes DO NOT use these
  • 15. Stage two
    • Pull out the undesired canes and wood
  • 16.

  • 21. Recap……..
    • Select the canes and spurs that are wanted for the coming season
      • and cut off the rest
    • Pull out the undesired canes and wood
    • Wrap and tie the canes onto the fruiting wire
  • 22. What canes do you select?
    • When selecting canes, the following characteristics should be considered:
  • 23. Cane Selection
    • Well matured canes with good colour,
      • brown to the tip and no green
    • Free from damage by pests, diseases and machines
  • 24. Cane Selection
    • Average diameter (ie not too thin or too thick)
    • Internode length 60-80 mm
    • No watershoots
      • They are not fruitful
    • No laterals
      • They are also not fruitful
  • 25. What are laterals?
    • Shoots that arise from the main shoot
      • Like branches
  • 26. Laterals Lateral bud
    • Laterals come from the lateral or prompt bud
  • 27. Cutting a Cane
    • Before tying down you need to cut through the last node
    • Make Sure....
    • You remove the bud BUT not the swelling
  • 28. Cutting and Tying
    • When cutting a cane
    If this is the last node you want to keep Then cut the cane here
  • 29. Cutting and Tying
    • When cutting a cane
    Tie the cane in the last internode
  • 30. Cutting and Tying
    • When cutting a cane
    The swelling will prevent the tie from falling off But you must remove the buds so they don’t burst
  • 31. Next….. Spur Pruning
