After repoting my Gardenia Bonsai... Ive noticed that there is white fuzzy stuff growing up its trunk. Is this normal?? Is it mold? Someone told me it might be spores. Did I kill my tree? I also noticed that I watered the tree once... after I repotted it... and now the soil hasnt needed watered since. (I used MiracleGrow Moisture Control) Is this normal?
