I planted a beautiful little Japanese Maple 'Deshojo' in Spring 2021. It has vibrant red leaves in spring (unusual!). They go green in summer and back to a more muted red in autumn. It has done really well. It is now 1m tall and has looked very healthy until now, but now the new leaves at the end of each branch have gone all crispy and dried. This is not surprising as we have had the hottest, dry summer ever here in northern France with temperatures up to 40ﾟC; but should I trim them off?
Secondly, and unrelated as it was happening before, the most central branch has died and if I cut it out that means it will have a hole in the centre. Could I do that and perhaps strap the other branches together to fill the gap? (Like a belt around it.)
For both questions, would I do them now or out of growing season in winter as someone told me?
Thanks so much!!
P.S. I've tried to post a photo and it won't accept it, even though I've reduced the size.
