All the himes do this in my experience, it's when you get the mixture of old and new that the interest increases, as yours is showing Xi.
Old leaves are darkening and curling up, but that new growth is turning into quite the little branch now:
Kotohime seems to have given up doing anything with its main branch, but those side shoots are growing with astonishing vigour!
14th April 2022 and my Kotohime has burst into leaf the last couple of days. I do enjoy the himes, they are just so cute.
24th March 2024 and I haven't posted this one in a couple of years. Just leafing out today in some welcome sunshine.
