Hi! I'm new here and have been taking care of an orchid that my office has had for a while. It was moved to a new pot and orchid soil a few months ago, then an ice storm hit that knocked out the power for 2 weeks. Recently it has dropped one leaf and looks like it will drop another! The rhizome is turning yellow and black and there are small bugs crawling in between the roots😟. I want to know what to do to save it!
