Parts falling off cactus assortment: causes and fixes

Check whether pads, segments or offsets are loosening, and whether the stem is soft or shriveled. Compare the signs before changing care.

Most likely cause

Overwatering. Ease off watering, check drainage, and inspect for rot at the base if it feels soft.

Other possible causes

Not a match? Compare the signs below to find the one you have.

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.

Prevention

Water only once the soil has dried out completely, keep it in bright light, and protect it from cold drafts and knocks.
