Things happen fast in the spring!



The short video above was captured at the NMSU viticulture vineyard at  Fabian Garcia Agriculture Science Center in Las Cruces. In this time lapse video you can see the buds on Sangiovese (our earliest budding cultivar at Las Cruces). It was captured with a camera that takes photos about on a 24 hour cycle. Of course, right now the same vines are almost ready to bloom.

Photograph of Malbec at approximately the Modified E-L stage 15 or 16: 8-10 leaves separated, shoot elongating rapidly,  single flowers in compact groups. Notice that the flowers are not yet open....I have had experienced grape growers tell me their vines had "set fruit" after seeing these unopened flower buds. But they were mistaken. What they saw, what is visible in this photo... are just...unopened flower buds. It will take some more time for them to open, shed pollen (anthesis), and then effect fertilization of the flower to form a nascent grape berry.

Late spring snow and cold nights...possible damage in across the state in New Mexico vineyards


Looking down rows at Santa Ana Tamaya Vineyard, April 13, 2020, notice the advanced stage of the shoots?
A closer look the morning after...flagging shoots are already present and visible. These are Chardonnay shoots at the Santa Ana Vineyard, April 14, 2020.  
Looking down the rows at vineyard in eastern New Mexico...April 13-14, 2020

bud break and beyond

Kim VanDyke sent this photo...Cabernet Sauvignon beginning the 2020 season. Notice the 'apical dominance' being presented on the shoot visible towards the left of this photo? The most distal buds appear to have initiated growth before the more basally located buds.

Pruning wood removed from Refosco and Gewurztraminer vines in the rootstock research plots at the Farmington, ASC. Notice the difference in color of the wood? One is light and the other further up the row towards the truck is more red in color...which corresponds to Refosco and which to Gewurztraminer?  BTW: no budbreak evident at this location.
