I have a 25 years old Rowan Tree in my garden.  I have just noticed some dark brown stick exudations (sap?) on its trunk.  I have searched the internet for an explanation but can find nothing that really helps.  Could somebody tell me please is this a natural occurrence for a Rowan Tree of this age in Spring or is it something I need to worry about?

Many thanks

Sounds like a canker. If it is you need to cut it off.

 

 

Thanks everybody but I think to whole tree might be dead.  Wait an see what happens.  If it doesn't leaf up, I think the thing to do will be to take the smaller branches off and then plant something, ivy, clematis, honeysuckle or some such, at the base.  Probably in a large pot so the soil is new and disease free.

I wouldn't use the wood of a diseased tree as a support for plants.

That's you told nut.

Trouble with dead trees is they fall over eventually leaving the climber stranded.To say nothing of passing on their coral spot and other delights

I have a rowan that's looking rather sad, the leaves are turning yellow an have brown blotches on them, could this be canker?

Kathy, did you have a lot of rain over the winter?  Does your soil drain well?  Rowans hate waterlogged soil.  Doubt if it's canker unless you have sap oozing out, like Valderie's tree.
