Hi, my plant is sick. Black spots and yellow leaves. What...
Sounds like rotting or overwatering. I would recommend taking the plant out and inspecting the root system if the roots are wet, smelly, or or clearly rotted I would recommend trimming your roots, giving it about a day to callus before you repot it, and then repotting it and some either more well draining soil, depending on the plant that youβre referring to because there arenβt any pictures so I canβt give any more recommendations other than that. If itβs an orchid, then I I would recommend getting some orchid, bark to repot. If youβre not already using that because orchids can write very easily, and their root systems are very delicate.
