How to Prune Grapevines Part Two cane pruning
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
Cane Pruning • Canes from the previous season are rapped around fruiting wires and then tied down at the ends
Cane Pruning • There are many different versions and types of cane pruning
Or two canes This is the same vine but later on
Cane Pruning Technique • Canes are between 8-20 count nodes • Spurs are retained to produce replacement canes for the following year
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
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
Canes • Make sure you DO NOT select canes older than last seasons • These will not contain buds that are fruitful
These were last years canes DO NOT use these
Stage two • Pull out the undesired canes and wood
Stage Three • Wrapping and tying the canes onto the fruiting wire
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
What canes do you select? • When selecting canes, the following characteristics should be considered:
Cane Selection • Well matured canes with good colour, • brown to the tip and no green • Free from damage by pests, diseases and machines
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
What are laterals? • Shoots that arise from the main shoot • Like branches
Laterals • Laterals come from the lateral or prompt bud Lateral bud
Cutting a Cane • Before tying down you need to cut through the last node • Make Sure.... • You remove the bud BUT not the swelling
Cutting and Tying If this is the last node you want to keep When cutting a cane Then cut the cane here
Cutting and Tying When cutting a cane Tie the cane in the last internode
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
