This acclimatisation process, called winter hardening, is particularly delayed in a large zone north and west of the Black Sea, extending into Hungary, where weather conditions were among the warmest on our records for this period. Unhardened or weakly hardened crops can suffer frost-kill damage in the event of a sudden freezing-air intrusion. Nevertheless, frost damage has been minor so far due to the same mild weather conditions, and, in accordance with the latest weather forecast, no further frost-kill damage is expected until the end of January.
