Orchids need healthy leaves to survive and thrive. If your orchid’s leaves look unhappy, take this list of common problems as a starting point to your diagnosis. Notice that some symptoms appear several times for different causes. For instance, certain signs of overwatering and underwatering are the same.
It helps to pay attention to the look and feel of your orchid’s leaves when the plant is healthy, so then you’ll have a good frame of reference to recognize a problem. While any one of these symptoms can indicate a problem, not every dark spot or yellow leaf is cause for concern. For example, older leaves (those lower on the plant) may yellow, develop spots, split down the middle, or fall off entirely. This is okay, as long as healthy new leaves are growing.

that’s a really useful list of problems. i’ve had orchids with leaves curled under, and didn’t know it was a problem. it’s good to know also that it’s not necessary to worry about every little spot
