My tree has presently got windburn, it didn't get quite enough water
this year.

Which begs the question... How much water is enough water for an Acer in
a pot? And can it actually have too much - assuming the pot is well
drained?

My small potted Acer glade is looking a bit ragged this year. This was
because I was trying to water them with rainwater - as I thought they
needed (or were, at least, best suited) to an ericaceous compost - but I
was corrected on this necessity a month or so ago. However, the watering
follow-up question wasn't answered.
