japanese maple - atropurpureum

 The edges of the leaves have turned a lighter colour and are very dry to
the touch.  What can I do to restore the maple to looking good again.
It's only 2 feet tall and is in a container.

 may not be the problem but ive just discovered my tree (18 inches) was
attacked by scale insects,it had all the symptoms you described,I was about
to dispose of it thinking it was dead but 1 leave has regrown on the trunk
the rest of the branches are bare probably dead, i was advised to drench in
pesticide not quite sure what to do now as it looks very odd any help would
be welcome

 I have had the same symptoms at the bottom of our garden.

We moved it nearer the house to prevent wind damage, but similar
symptoms have come back, as well as curled up leaves.


I've cut back most of what looked to be dead, and am now left with a
fairly healthy looking couple of large branches.


Will wait and see what develops!

 This sounds like wind damage or could be that you let the plant dry out.
Both will produce the effect you describe.
Not a lot you can do to improve it now. If it is only a few leaves you can
cut them off.

I have heard of people trimming back each leaf to the undamaged bit but I'm
sure this would look odd and the edges would discolour.

Place in a more sheltered position next year.

I have stopped selling these as they are expensive and we do not have the
climate for them in the north of England.
Failing that keep them in the conservatory.

It isn't over-potted, is it? They absolutely *hate* that. Moving up
one size at a time is the safe policy. The container needs to have
good drainage holes, too.  I also prefer John Innes to peat-based
mixtures: it's easier to wet properly.
