Why is my indoor orchid dying?

There are many reasons why an indoor orchid might be dying. It might not be getting enough light, it might be getting too much water or fertilizer, the potting mix could be the wrong kind, or there might be pests or fungal/bacterial infections present. The best way to figure out what’s wrong is to check your plant for signs of stress (yellow leaves, wilted leaves, fungus, scorched spots, etc.), and cross-reference its symptoms with potential issues.
