每日吃瓜

I'm hoping someone here can give me some advice! I have this lovely Japanese Maple bonsai which I have had for nearly 4 years now. I'm no expert in this area but the last two years the leaves have appeared to grow pretty deformed. Certainly way less leaves too. And also I've noticed the branches are mostly white now, does that mean they have died?

What actions do I need to take to revive this? I have repotted into fresh bonsai mix this season. I feel like those dead branches need pruning? But up to what point to encourage new shoots? Right up to the main stem?

I've attached a photo of the bonsai from a couple of years ago when it was healthy.

Thanks in advance!

Since you have repotted recently there is nothing else to than wait for it to recover from that.

Dead branches can be removed, but they do not need to be removed. If not removed they will drop sooner or later.
