![Page 2: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/2.jpg)
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 Technique Canes are between 8-20
count nodes Spurs are retained to
produce replacement canes for the following year
![Page 9: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/9.jpg)
Cane Pruning Technique Vines are head trained
canes and spurs are selected from the head
Vines may be unilateral or bilateralCanes run one way or both
ways
![Page 10: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/10.jpg)
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
![Page 13: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/13.jpg)

These were last years
canes
DO NOT use these

What canes do you select? When selecting canes, the following
characteristics should be considered:
![Page 23: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/23.jpg)
Cane Selection
Well matured canes with good colour, brown to the tip and no green
Free from damage by pests, diseases and machines
![Page 24: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/24.jpg)
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
![Page 25: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/25.jpg)
What are laterals?
Shoots that arise from the main shootLike branches
![Page 26: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/26.jpg)
Laterals
Lateral bud
Laterals come from the lateral or prompt bud
![Page 27: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/27.jpg)
Cutting a Cane
Before tying down you need to cut through the last node
Make Sure.... You remove the bud BUT not the
swelling
![Page 28: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/28.jpg)
Cutting and TyingWhen cutting a cane If this is the last
node you want to keep
Then cut the cane here
![Page 29: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/29.jpg)
Cutting and TyingWhen cutting a cane
Tie the cane in the last internode
![Page 30: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/30.jpg)
Cutting and TyingWhen cutting a cane
The swelling will prevent the tie from falling off
But you must remove the buds so they don’t burst
![Page 31: part 2](https://reader035.fdocuments.us/reader035/viewer/2022070316/5559dfb0d8b42a34498b4a9a/html5/thumbnails/31.jpg)
