Gobelet
pruning is a traditional short pruning characterized by a
short trunk and long branches, broadly open and fanned out,
providing efficient airing to the vine-stock. The number of
branches depends on the potential crop and planting density.
There are 3 to 7 branches.
Gobelet pruning is commonly used for Côtes du Rhône vineyards,
mainly in Châteauneuf du Pape (Vaucluse department, Provence),
where mechanical harvesters are not allowed, as well as for
erect-shoot varieties, when tying-up is not necessary or not
allowed, making mechanization more difficult to implement.
Example of 4-branch gobelet pruning
Planting
requires a perfectly prepared and sufficiently nutrient-rich
ground to facilitate the full growth of the plant and its
root system.
After
the herbaceous-development stage, vine shoots are pruned in
winter so that 2 eyes remain. This step aims at insuring the
suitable rooting of the plant for the following year. It is
recommended to prune as late as possible, in order to avoid
spring frosts in sensitive areas.
During the summer, a stake can help support the vegetation.
The
following winter, the 2 shoots are pruned so that 2 eyes remain
and form the spurs. In summer, the shoots can be trimmed (green
pruning) to ease vine treatment and cultivation.
The following winter is the time to
prepare the structure of the gobelet: each shoot is pruned
so as to form a 2-eye spur. The 4 spurs will then form the
branches that will support future pruning. During the summer,
the shoots can be trimmed (green pruning) to ease vine treatment
and cultivation.
Year
after year, the shoots coming from previous pruning on each
spur can be kept or cut out.
To prevent the vine stock from lengthening
and ageing, it is important to prune the lowest and better-exposed
shoot so that 2 eyes remain.
The gobelet shape results from those
various steps.
