Hi Folks,
I have a mature Western Red Cedar which seems to have given up the ghost at a rapid pace.
I am not a tree surgeon myself but I have asked 3 local reputable tree surgeons to look at the tree and none of them can tell if it's diseased and none of them can think of an explanation for its rapid decline in foliage colour - since the photos were taken 3 weeks ago the branches have almost turned completely light brown in colour.
One guy said he thought it might have struggled with the recent years of drought then very wet conditions this year (we live in Kent) - which sounds viable but it is a mature tree and well established. There are no obvious signs of external disease or fungi (though there is a dark core in the cutting - see photo).
I did my own research before the surgeons came over to check (and quote for removal if required) and the most common conditions seemed to be thuja blight or, if I was lucky, the tree was 'flagging' and would recover.
It would be great if anyone could share their opinions as, apart from the cost of removing the tree, I hate to take down mature trees and this particular tree has a prominent place in our garden.
But, with its seemingly rapidly decline in health (it seemed to go from green to the state when these photos were taken, in less than 5 or 6 weeks), I'm worried that it could become unstable and fall on to our neighbours house if not dealt with quickly.
The tree surgeons all seemed to think the tree would be fine (ie not dangerous) for a few months and it might be prudent to wait until winter to see if there any signs of recovery before taking a decision to take it down.
The other point to add to this case - and it could be a red herring - is that I had to remove a silver birch earlier in the year which was only about 20ft away as it had a fungus and was literally falling down.
And. elsewhere in the garden, I think I have seen in spring a small clump of honey fungus around the base of an apple blossom tree. From reading, I'm not sure honey fungus would readily transfer to a Western Red Cedar but may be it could and it has...
Thanks for reading, I would really appreciate the advice of a 'disease expert' in this matter.
