Polling: as part of the growth of the vine we talk about “apical dominance”,
this meaning that the lengthening of the shoots is favoured.
As time passes, however, the leaves at the base “age”, in other words they are no longer so effective in their work of photosynthesis.
Cutting the tips of the shoots, however, results in the plant not using all its energy solely towards the apex, but stimulates growth of the lateral buds, which form new leaves, younger and more efficient.
This polling is carried out at the end of spring, when the plant needs new energy for ripening the grapes.
Removing leaves: when the grapes have almost ripened, we go through the vineyard removing some leaves from each plant so that the bunches of grapes are well exposed to the sun and air circulates around them.
Leaf removal is important above all to prevent the bunches from rotting, which may come about due to excessive moisture around the fruit.
