Hello!!
An acquaintance has a problem a problem with a Loropetalum chinensi that is rapidly deteriorating and has leaves of an altered color. It would not seem to be under attack by parasites and my fear is that it has a radical problem because looking at the photo where you see the pot it seems to me that there is mold but I don\'t make text.
Can you help me understand what is happening to it? Thank you!
