My Cupressus x leylandii are getting dry.
Location - North west of Romania.
This is their third year , i had no problems with them so far . My entire garden is surrounded by these trees , and i think the infection is spreading. what is it and how can i stop it?

The last picture really makes me think Winter damage.
Wait a month or so for new growth to emerge, then you can prune the dead branches.

I think it s a desease because it s evolving. These are the pictures from 10 days ago. Now they look way worse. Are almost dead. And the problem is that the rest of them, that surround my garden are staring to have the same simptoms aswell.
