It happened 2 years ago too, but a lot less damage. I don't own the trees. There was a line of 5 when we moved it. 2 have blown over and the other 3 probably will at some point. But we're struggling to get something done about them. No one is claiming ownership. All I know is that not one is in my garden but I'm left repairing the damage. Anyone know where I stand legally with this? Can you imagine if my wife or dog were in the garden. I banned them from going out there yesterday.
Write a letter to the local council and tell them you think it's a safety concern.
