Phalaenopsis and other orchids respond quickly to any problems in their environment. Pimples are one of the signs of trouble. The first step in treating dark spots on orchid leaves is diagnosing the problem. Some phalaenopsis have naturally speckled leaves, so it can be a natural coloring. However, staining the leaves can also signify a bacterial or fungal disease. Bacterial leaf spot is quite common among orchids and can be aggressive and dangerous to phalaenopsis.
Stem rot most often afflicts Phalaenopsis and Vanda orchids and can be deadly if left untreated. Learn to identify, treat and prevent stem rot, or collar rot, in your orchid. #Orchid #OrchidCare #Phalaenopsis #StemRot
