I posted here before regarding an Acer Palmatum 'Garnet' which I was
given, in a pot, late summer last year. At that time, it was just
losing all of its leaves, and following some advice here, I decided not
to to repot or do anything this year, and let it establish itself first
and see how it did.

Anyway, despite being out all winter, it seemed OK and the last few
weeks there has been some nice activity with the leaves starting to
come out and now there is a reasonable amount of new growth.

Unfortunately, it has now taken a turn for the worse, and all of the
leaves are limp and drooping, much as I would expect if it had dried
out. It's still in the pot that it came in and that pot is inside
another decorative pot, but raised on some broken bricks to help
drainage. It seems to be draining OK but the soil is quite moist
following some heavy rain over the weekend.

So, what to do, if anything? Would I be OK repotting at this stage (I
seem to remember advice about only doing this while in its dormant
state) or am I best of leaving it to (hopefully) sort itself out.

If I repot it, I have some John Innes No. 3 (I think!) - is this OK if
I mix it with some pebbles or gravel to help drainage?

Thanks.
