BC Growing Degree Days (GDD) Update
Below is the October 2025 GDD Update from Summerland Research and Development Centre. This is the final update of the 2025 growing season…and after 15 seasons of GDD reporting it is also my (Brad Estergaard) last update (Ben-Min will continue in 2026). 2025 managed to take the title of highest GDD in all the monitored locations.
Keep your eyes peeled for the Grape Bud Hardiness reports which will start shortly.
