From Sept 1 to Dec 31 we had accumulated 1242 GDD at Harrow, 1180 at Ridgetown, 1108 at London and 1210 at Sarnia. Approx. 120 GDD more than a year ago. As of January 1, 2025 we reset to zero GDD and track accumulation through to green up and beyond. Green up usually begins after 250 - 300 GDD accumulation. The wheat crop is still developing maximum cold tolerance, that will likely be completed by end of January.
