Generally the sap starts to flow between mid-February and mid-March. The exact time of year depends upon where you live and weather conditions. Sap flows when daytime temperatures rise above freezing (32 degrees Fahrenheit / 0 Celsius) and nighttime temperatures fall below freezing. The rising temperature creates pressure in the tree generating the sap flow. This is basically a transfer of the sap from the tree above the ground and the root system below the ground. The sap generally flows for 4 to 6 weeks, with the best sap produced early on in the sap-flowing season.
These conditions are not met in the fall and the sap quits running in less than 6 weeks after it starts as stated above due to rising temperatures.
