Bud Mortality Counts at Los Lunas vineyard

The table below contains results of bud dissection and assessment of approximately 276 dormant buds. Each bud's primary, secondary and tertiary growing points were inspected and if they appeared black instead of healthy green in color they were marked as "dead". Upon first glance it appears as though the one year old Touriga Nacional vines fared the worst with about 86% of its primary growing points appearing dead, followed by Petit Verdot. I will repeat this assessment later in the year when we begin dormant pruning and use the mortality then to determine how many buds to leave for the 2021 growing season.
