How to tell when lotus root has gone bad
Look for mold or mildew.
Examine the root for signs of mold or mildew. Any dark green, black, gray or white growth on the outside of the root is an indication that it has spoiled.

Select from:
(1). If your root has mold or mildew on it, you should discard it. Observe to see if the root is soft.
(2). Rose dimes, or similarly rancid looking projections, should not be given to toddlers, as they may have a bacterial or fungal infection. If no mold develops, the roots of the plant are likely to rot.
(3). If this occurs, it has gone bad. Mildew, for instance, is typically mold-like, and will produce dark, black growths on the plant and/or buds.
(4). Mildew may also be a sign of rot. Look for scorch marks or discoloration on new roots, that may indicate root rot or mildew.
