I have that Acer - the only one that I have found that likes full shade. November-Feb is the optimal time to transplant, when it is dormant and leafless.

If it is in a pot and you want to put it in the ground then you can do that now. I would add some bonemeal and ericacious soil into the planting hole first and keep it well watered.

Thank you Kildermoire from a Scot living in Brussels. It is in the ground so will move it at the end of the year.

that is november or febuary realy . i prefer early spring as the plant doesnt have to sit in the cold ground damaged or shocked all winter .

Sounds like good advice NP - I will do this in February. Thanks.
