ACER

My suggestion would be to move it in the autumn as soon as the leaves have fallen. But to help prepare it for the move, take a spade and thrust it into the soil all the way around the tree as far out as the branches spread. This will encourage it to make lots of new fibrous roots which will help it when it is moved

Thank you for your reply. When do you suggest that i prepare it for the move?

You can do that now
