There seem to be some small flys flying around my trees. Also I noticed some white tiny bugs in one of my bonsai soil. What do you think it is. Also I sprayed them with neem oil and put the bonsai with bugs outside.
The answer to every question is always, "it depends". You need to give more info on conditions: indoors/outdoors; sun/shade; history/length of ownership; general health/major/minor potting, trimming, ad infinitum. Detail or close pictures and full portrait of all individual plants in question.
