I have some young willow planted as part of a mixed native hedge....about 18 months in the ground now....... and the rest of the plants are thriving and growing away while the willow has some black stems and poor leaf growth, and looking generally miserable.
I wonder does it have the same problem as yours Donnamarie ?

Its more than likely drought or the fungus rust. In both cases a little extra water to the base of the plants would not go astray. Tell you what, put up a pic of the poor willow. I may be able to tell you more if I see them.

My willow has suffered the same this year - and to think I was blamed because of my bad pruning! Evil or Very Mad

I suspect its Willow Scab or Black Canker

Info : http://www.treehelp.info/pages/Publications/pubTDA86.html

What should you do?
As these diseases are so weather dependent, trees badly damaged in one year may escape infection in another. The onset of dry weather also brings a rapid reduction in new infections. Most trees recover quickly even from severe attacks, so chemical control is rarely warranted in ornamental plantings.

Drought it certainly isn't...not in my case anyway. The hedge was kept well watered ( by Nature ) last year, and the rest of the hedge is growing really fast....it looks more like a disease.....Black Canker sounds like a possibility......

Not exactly black, but this is what willow affected by rust looks like............



Look familiar?

we're getting what looks like light orange fungus spots on the leaves of the kilmarnock willow - though it's in need of a haircut, there wouldn't be much airflow through it.
