Root rot is a common problem for many types of plants, including devils backbone. It occurs when the roots of the plant are consistently exposed to too much moisture, causing them to rot and decay. Signs of root rot include yellowing leaves, wilting, and a foul odor coming from the soil.

To treat root rot in devils backbone plants, you need to act quickly. Carefully remove the plant from its pot and inspect the roots for signs of decay.
