Rowan ring barked by worms

Recommended Posts

Better comment will follow but that looks to me like a bleeding canker with nematode-like critturs feeding on the juice and woodlice on decaying wood.  The animals are there because of the tree's ill, they're not causing it.

 

The prognosis re the canker? Not good I would have thought but await more informed comment.

I don't think the worms are the primary issue, rather they have colonised the area due to the dysfunction and decay in the heartwood and sapwood. There looks to be some slime flux/bacterial effusions going on too.

 

The real cause is probably 'strimmer rash' caused by careless grass cutting.

Thanks for your reply, the only reason I suspected pest is one of the other trees being affected is in a bed and I wouldn’t have thought that it would have been attacked with a strimmer but maybe it was.

Looks like what we call mower or string trimmer blight. Perhaps exasperated by South West disease. Then colonized by further nasties. Common as mud when no mulch ring is installed at planting.
