Flowering is over and the clusters have set. The grapes appear to have set fairly well so that the crop looks promising. Today is a very windy day and very windy days can cause problems during flowering with the set- fortunately we are done.
With the clusters now set we can begin leafing, during flowering this would damage the clusters. The machine is a giant vacuum which sucks in the leaves, chops them up and blows them out at the ground.
We remove leaves only in the cluster growing area, the rest of the canopy is not affected. This is to permit air circulation and reduce the possibility of mildew. In a cool climate, such as ours, mildew is always a possibility.
