Q.Bird Of Paradise Is Unwell
I have been trying to find some help with my indoor house plant, a white bird of paradise, but haven’t had any luck. I’m hoping you can help me… I’ve had the bird of paradise for a couple years and it’s such a beautiful plant! It has started to get dark spots along the stems, and in one area this has progressed to a black patch. From googling I think it may be fungal disease, but I can’t find any solid information about how to treat it… please help me save it! Thanks so much!
