When to prune the vine?
The vines are pruned twice, end of winter after severe frosts and in summer during fruiting.

Prune the vine in winter:
The vine is, at this time, in vegetative rest and the sap has descended.
The ideal period is therefore between February and March, avoiding periods of frost.
If the weather is mild in your area, it is possible to start pruning the vine as soon as the leaves fall.
Spring pruning in cold regions:
In colder areas where severe frost can still occur in March, you can wait until very early spring to prune, but this is the last moment.
Prune the vine in summer:
It's about afruiting size, it is not mandatory.
It consists of limiting the number of bunches to a maximum of 5 per vine shoot and cutting the vine shoots that do not have them as short as possible.
You can also eliminate very small clusters as their yield will be low.
General principle of winter pruning
The pruning of the vine is based on the bud selection also called eyes.
Some will not give grapes while others will very fertile.
- The most fertile buds:
These are the ones that appear on the one-year-old wood (the one that grew the previous year)
- The buds that will not give anything:
The buds that grow in the axils of old wood (the one over a year old) or an already cut twig.
Basic pruning to have beautiful clusters on your vine
- First eliminate the dead wood
- Then remove the stems that grow at the old wood base
- We must then focus on stems that have grown in the past year
- Cut these stems leaving at least 3 buds (eyes) per stem.
- They will be the most fertile and will give grapes.
- If you cut the entire stem you will not have grapes.
- Over the years, you will make sure to remove old wood for leave room for new growth
- It is the experience that speaks ...
