Crown or stem-base rot

Water trapped around the crown or prolonged saturation can damage the plant's central growing tissue and may allow rot organisms to spread.

Safe first checks

Isolate the plant, keep water out of the crown, and inspect where firm healthy tissue changes to soft or dark tissue.
Check moisture below the surface and through the root ball.
Confirm that water can leave the pot freely.
Compare root firmness, color, and odor before changing the routine.

What to avoid

Do not water again, repot, and fertilize on the same day unless the roots show an immediate need.

Record and follow up

Track root-zone moisture, pot weight, new growth, and leaf posture over the next care cycles. Judge the change by new growth rather than old damaged tissue.

Seek qualified local help when damage is severe, rapidly spreading, or may involve a regulated pest or disease.
