Wind Damage Vine Shoot Tips - UPDATE 1/11/2011



These are a pictures of wind damaged shoot tips taken in the Sellicks Foothills sub-district of McLaren Vale. The vineyard has just begun flowering (EL-19 Early Flowering) and is still rapidly growing. The main growing tip has been rubbed away by high winds and lateral shoots are beginning to push to compensate for this.

Fast growing vines and certain cultivars are more prone to wind damage. Damage to shoots is most common in spring and early summer when new shoots are fast growing and weak (green). Later in the season, after shoots have lignified (turned brown), leaf damage is more common. This late season wind damage is very common in the Sellicks Foothills sub-district of McLaren Vale.

Heavy leaf wind damage, late in the season, can cause a reduction in photosynthesis that may impact fruit quality.
