A knock or a recent move
How to tell
Pads, segments or offsets came away after the plant was moved, repotted or bumped. Many cacti shed loose pieces easily.
The fix
Nothing more to do for the plant. Let a healthy fallen piece dry for a few days and it can be potted up as a new plant.
Underwatering
How to tell
The stem looks shriveled and wrinkled, the soil is bone dry, and loose offsets come away easily.
The fix
If the soil is bone dry, water thoroughly, then check it more regularly so it doesn’t dry out that far again.
Cold drafts or temperature swings
How to tell
Soft, glassy or darkened patches appear after a cold night, and damaged pieces fall away.
The fix
Move it somewhere with stable, draft-free temperatures.
