Hi, dear bonsai lovers. I have this Ligustrum for two years now and since 2 weeks ago, it started slowly shedding leaves -5-8 per day-. I must mention that I live in northen part of Italy- winter now- so I keep it indoors.
I attached a photo with the whole tree- that still looks healthy- and with the shaded leaves. Some of them have yellow&brown coloration, some of them are just wrinkled.
I would be more than grateful to anyone that could point me out the problem of my little tree.
Thanks,

Even evergren trees replace their leafs, not just as fast as deciduous.

Bringing trees inside living room conditions is allways a gamble. Did you recently got a cold spell that kick started your heating system and dried up the air indoors?

it may be due to a change in temperature, since when he returned, I have a doubt that a Ligustrum is

Ligustrum sinense.
