Two dying renantheras??
Dear all:
I have two very sad renantheras (kalsom and citrina) whi were doing fine until about a week ago. The lower leaves started turning yellow at the base and falling off now almost all the leaves have dropped!! I had treated them with peppermint/oil wash for false mites 3 weeks ago but none of the rest of my orchids did this. Is it overheating? Virus?? The kalsom ive had for 5 years. The citrina’s keiki somehow dont seem affected but the new root tips have shrivelled up. They are in a sunny bathroom. Any ideas whats going on?? Help please.
