Dutch Elms Disease?

[finchyo]

Hi all,

 

Did a crown reduction on a healthy, mature English Elm the other day. Did the reduction as it is very close to the house and the customer is worried about falling branches etc. There was no external signs of any disease but when looking at some of the sections cut off I saw dark staining in many areas inside. Does the tree have DED or is this a usual colouring? I think the tree has lasted this long as it is right next to the sea or the fact it doesn't have any other elms around it as I could see.

 

Cheers

doesn't look like it to me. its usually a thin black brown line that follows the annual rings, not blobs.

 

if it had it you would definitely see external signs.

I am reasonably sure that those brown blobs are quite common in elm, and i have never got around to finding out what they are. Sorry that i could not have been any vaguer

Could the brown blobs be compartmantalized woodpecker damage?

yeh it probably is just woodpecker damage, I saw quite a lot of that on the bark of the tree. Hopefully the tree will be fine for many years to come, if not then there is another job for me to go do
