I am not a willow expert, but this sounds like drought to me. If you're
sure you're giving it enough water, is it possible that the water isn't
reaching the tree efficiently. Is your tree grafted, for instance, and if
it is, have you checked that the graft/union is still intact?

I have a salix x sepulcralis chrysocoma in a large planter. A couple of
months ago it was affected by scale, which I manageed to treat
scucessfully,
now it has another problem. Almost half the leaves have gone very dry and
curled up, some have started falling, it's happened very quickly, in the
past 4 or 5 days.

It's planted in potting compost with pearlite, gets plenty of water and a
regular feed. I have other ordinary willows in pots which are all doing
fine. I am wondering if I am doing something wrong, or if I have just
bought
a dud tree.

Any advice would be much appreciated.
