I have a indoor bonsai in a shallow container- have had this about 2 months- leafy kind that would get tiny white flowers, usually one at a time.
was very "happy" until the last couple weeks, now dropping many leaves.
Of course, with the weather change we have moved it indoors- it is drier and not as sunny- we are going to move it to a sunnier window and see if that helps- we have kept it wet, ( the bonsai master said you can never overwater ?) and misted- said to not fertilze until after the 1st the year. It is just going dormant or ? I do not see any indication of infestation, fungus, etc. I have tons of outdoor flowering plants and am considered to have a "green thumb", so I am familiar with plant care----do you think the sunnier location will help or??
