Fruit Set Begins

Flowering began about 15 days ago, and we are beginning to see signs of fruit set. Fruit set describes the period after flowering when a fertilized flower begins to develop a seed, and, more importantly for us, a grape to protect the seed. We had a few storms and strong winds during the flowering stage, but we also had some sunny, breezy days, which are ideal for successful flowering, so we’re seeing a few issues within flowering – clusters with less than ideal “set” grapes – but overall things are looking great.
This period is crucial for cluster size and overall yield. Not every flower fertilizes – actually, averages seem to be around 30% in most vineyards, although this number can vary considerably. Cluster size and cluster density are determined by the percentage of fertilized flowers, as well as variety and clone.
