| Common phenomenon, if winter temperatures fall below -15°C; especially, if trees were not able to establish enough frost hardiness before; damage of that type occur in early winter following a sudden drop of temperature.
Curative measures
Usually not necessary; fertilisation in late summer may also cause such symptoms, therefore no fertilisation at that time!
