cane pruning

1. How to Prune Grapevines Part Two cane pruning

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

12. Canes • 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

18. Stage Three • Wrapping and tying the canes onto the fruiting wire

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 • Laterals come from the lateral or prompt bud Lateral 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 If this is the last node you want to keep When cutting a cane 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
