Dawn Redwood disease

Asked July 10, 2014, 12:35 PM EDT

I have a few Dawn redwood trees which are having random branches leaf out and then die off on mature specimens. Not sure if this is fungal or insects affecting trees?

Metasequoia glyptostoboides is the Latin term for Dawn Redwood a needled tree that sheds it's needles in the fall (deciduous). After this past winter's depredations we are finding deciduous trees and shrubs exhibiting strange habits. At the moment we are calling this Twig Burn. This condition causes the twig juncture with a main branch to be injured by the heavy cold in January through March at least. The condition exists through early spring long enough for the leaves (needles) to develop and when the sap currently in the branch is used up then the leaves shrivel and the whole twig dies. This shouldn't hurt the tree as a whole and it will survive to leaf again. Thank you for using the Ask An Expert System.
