I have a minuature Japanese Maple 'Deshojo' bought 2 years ago and it has done well since. I live in Northern France, it is in full sun in the afternoon but there are only a few weeks it is really hot here.
The top of the central branch has died. If I trim it out the dead section, it will leave a 'hole' in the centre and the other branches are quite spread out. Could I perhaps pull them in to the centre a little by tying a strap around them? Also, I believe I should wait until spring to trim it, is that correct?
