2020 Annual Cycle of Growth

It's that time again to update my annual of cycle of growth form. I summarized the information that I've been keeping since 2015 and provided the form in a blog on September 2019. It is something that I read about in Ed Hellman's online post called Grapevine Structure and Function.
This year, I will add Barbera to the form. This is the first year that we have laid down canes for the Barbera which we planted in 2016.

Since I began keeping data in the form, it seems that the Chardonnay are always the first to bloom. This year, we first saw the Chardonnay blooming on June 20 and by June 22, at least 50% of the flowers were blooming. The Cabernet Franc clone 214 was also around 40-50% bloom on June 22. We noticed that there was a difference between our two Cabernet Franc clones, 214 and 327. Clone 214 is always earlier to bud break than 327 and it is earlier to flower. The Barbera and the Auxerrois were around 20% in bloom and the Chenin Blanc was at more like 10% bloom. The Cabernet Sauvignon was not in bloom at all until June 25. Bloom lasted about a week or so before everything appeared to be at 100% bloom. All of our varieties are now at various stages of berry set.
