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.

for the leaves tha have gone brown and crickly- nothing! but for the rest od
the plant keep it well watered - it sounds like water stress to me.

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.

And if you can, and you have suitable soil get it out of the container and into the garden in a sheltered but not deeply
shaded part of the garden. No trees are really happy in containers and these Acers are particularly difficult to keep in
prime condition.

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

Discoloured leaves
 

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!

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.

How does the plant know that is is over-potted?
What is the difference between an overpotted plant and one put in the open
ground ab initio?

I put a very young Acer palmatus atropurpureum in a 45cm pot about ten years
ago. It has thrived all the time, in spite of starting by being overpotted
and now being underpotted.

When the newly-formed tips of its roots reach stagnant water with an
inadequate oxygen content: they can react to this by rotting.

The water in the open ground moves about, dragging oxygen in, and
also, I think, helping to stop malignant organisms building up to a
dangerous concentration.

Su it often works out ok, with maybe just a slowing of the ordinary
rate of growth, especially if your watering technique is right for the
plant. But one can't be certain of getting away with it.

That does not sound like overpotting at all. Surely that is overwatering
combined with lack of drainage.

That sounds like waffle. Let's call a plant in the open ground grossly
overpotted. What then?

I have handled potted plants of one kind or another for close on sixty years
now, and have yet to find out what this "overpotted" lark is about.
Frankly, it sounds to me like an old wives' tale. [Franz Heymann]

The effects are much the same, yes.

As I say, you don't have to believe me. I think I may have mentioned
that your watering technique could have had something to do with it.
