Nova Scotia sap flow forecast

The next several days for Nova Scotia's sugaring country, read the way a sugarmaker reads them: how cold the night gets, how warm the afternoon gets, and whether that adds up to a run. The season here usually opens March.

Northern Nova Scotia's Colchester–Cumberland area is where the maple association's president describes the province's producers; Earltown's Maple Mist Farm taps about 8,000 trees (CBC, 2016).
