My Bonsai is dying and a white mildew is on its root
My bonsai has a 3 or 4 part root that combines to one and then its foliage starts, I don't know the type. Some days ago its foliage starts wilting and after 3 days there is just 4 or 5 foliage left :(. Today I noticed a white powdery mildew on one of its root parts. I have read that the root should be removed. but I am not sure this is ok. I am so depressed, because I have had this beautiful bonsai for 3 years. I would really appreciate if someone can help Plzzz.
