sorbus aucuparia sudden death

Recommended Posts

got a customer we took down a rowan for back in may '09. they said it started leafing up nicely then suddenly the leaves disappeared and the bark on the trunk went brown within a couple of days so they called us to remove..

I noticed on every branch union tiny (2mm) across clusters of dark red very shiny little dots, not sure if they were insects or growths..

there was no evidence of poisoning from below ground as surrounding plants were unaffected, the garden pond was healthy (fish swimming etc..)

anyway customer just emailed me wondering if i had ever found what it was because theyre now worried the same will happen to the nice rowan in the front garden.. any ideas?

sorry no pics 'doh'

oh it was about 15 to 20 yrs old.. thanks

Lack of pictures really doesn't help, but you know that.

 

 

Is it possible that the 'growths' were fungal?

Possibly Coral spot.

This is a saprophyte, which may of been in attendance due to a n other stress to the Tree, vascular dysfunction perhaps.

 

This is just guess work without any shots.

i thought coral spot (nectria cinnabarina (sp?)) only colonised on dead wood/dead oak branches? I could be wrong, but thats what i was told.
