The following shoots are thinned:
- absolutely all water shoots.
- any other infertile shoots without visible inflorescences, which emerge from the pruned spur. However, at least one near-stem new shoot must remain at each shoot position for the following winter pruning.
- if there are two or several shoots growing from one bud, the strongest one (with inflorescences) is retained, all others are removed. Many varieties have a tendency to produce several shoots from each shoot position.
Shoot thinning is carried out when the new shoots have reached a length of approx. 10 to 30cm, ie at a time in spring when the whole vine is still easily manageable.
