Final Photos of 2017 Fall Frost Tolerance Have Been Posted
The final fall frost tolerance sheet for 2017 has been posted. All cultivars have reached a deep maroon color and their deepest frost tolerance temperature. For Ben Lear and new Rutgers cultivars this tolerance is 24°F. Stevens tolerate 22°F at this stage until late October when some loss of tolerance accompanies extreme ripening and Stevens once more must be protected at 23°F. Early Black and Howes tolerate 23°F at the maroon stage. In some years, Howes have tolerated temperatures as low as 20°F at the maroon stage but this was not the case in all years.
