2022-23 Bud Hardiness Report No. 9 - Nova Scotia

Attached, from Jeff Franklin and Dr. Harrison Wright, is the 9th Nova Scotia bud hardiness report for the 2022-23 year.  The Nova Scotia wine grape bud hardiness survey generates a bi-weekly report of the low temperature exotherm (LTE) values over the dormant period (roughly from late October to late April). 

Note from the research team: "The three remaining varieties in our survey have all deacclimated since the last survey date almost three weeks ago. Marquette and L’Acadie blanc deacclimated the most, by 4.2 °C and 3.1 °C, respectively, leaving Frontenac blanc as the hardiest variety in the survey. The timing of this event is to be expected given the temperatures observed in March and the deacclimation trends observed in the previous years of the survey. So far, the average temperature for March 2023 has been -0.7 °C which is very close to the 25-year average of -0.3 °C. Sap-flow has been observed in many hybrid varieties which coincides with this recent deacclimation. The 14-day forecast calls for temperatures to be average or slightly above which will promote further bud deacclimation and development."
