Cedar problem - help please?

[TotallyJules]

Hi all

 

Just looked at a 25 year old cedar in a back garden with browning of some needles. This is starting at the lower branches of the tree, the upper crown is unaffected so far. There are plenty of new shoots near the affected ones. There is no history of environmental change at the site. The tree has been getting worse of a period of three years. I've attached a couple of pictures to see if it helps. I'm thinking it looks like needle blight (sirococcus conigenus) but can't find much info that is based in the uk.

 

Many thanks in advance

That's a coincidence, a client asked me about this yesterday on his tree. exactly the same as your photos. I was a bit unsure myself?

Could there be a connection between the lack of moss and weeds in the grass and the health of the tree?

My initial reaction at first was abiotic conditions and said to client to monitor it!

Looked at one last week. No sign of pests and damage low (to about 3m) Grass has been treated recently. I wondered if the chemicals had vaporised in the high temp's and affected the needles. Or the grass 'treater' was a bit careless in the application.

 

Suggested to the owner to wait and see, because the higher canopy was vital with lots of healthy new growth.

Recent information indicates this is due either to weevil or Sirrococcus sp. If it's the latter the FC are asking that it is reported. I think these are pycnidia on the dead needles
