Sagos Zapped By Polar Vortex 2014
Potted sago palms have been successfully wintered every year in an unheated gardener's cottage in Nashville.
This unusually harsh winter (periods of 5 to 10 degrees) has turned them almost completely brown. During a lull in the cold a month ago, they were pulled out, watered, drained and returned to cottage. No visible improvement so far.
Rx please, Sago Doctors. Many thanks in advance.
