Growing Degree Days October 2023

October, 2023

Attached is the final Growing Degree Day update for the 2023 growing season.  20 year GDD averages added to the Summerland and Osoyoos long term comparison plots.  2023 now takes the crown for highest GDD by a fairly significant amount in all areas.

Time to shift gears…Grape Bud Hardiness reports will start being sent out later this week.
