Hello everyone,
I’m trying to figure out what is going on with my pepper tree. In the last 5-7 days a lot of leaves are folding (see pictures) and plenty other leaves are drying and falling down. I haven’t change the way I’m taking care of the bonsai in the last month. 3 weeks ago I made a general clipping and 2 weeks ago I sprayed it with neem oil. This leaves problem has come out only 5-7 days ago.
Any idea what is wrong with my pepper tree?
Thanks
