Last
weekend the climatic conditions were quite tough throughout the province, which
have impacted many crops and vineyards are not the exception. Throughout winter
AAFC is sharing bud hardiness reports to show the acclimatation of buds in
hybrids and Vitis vinifera varieties, information that helps
to decide pruning decisions depending on varieties. Unfortunately, last
weekend's event was quite cold and stayed for many hours, increasing the
potential damage.
We had a
similar event last year, which impacted different varieties and locations in
the province. At this time the cold event impacted broadly, it might be
possible to find areas with lower or higher temperatures. Regardless of the
variety, it’s important to assess the vineyard before taking further decisions.
As
mentioned, bud survival depends on many factors, such as variety, location,
vine health and age, management practices, crop level, etc. For more
information on bud hardiness, please take a look to the last AAFC
