Pests, webbing, and leaf spots on Pink quill

How to tell

Small, brown, limpet-like bumps stuck to stems and the undersides of leaves, often with sticky honeydew.

The fix

Scrape them off gently with a fingernail or old toothbrush, then treat with neem oil and keep checking.

How to tell

Fine webbing in the leaf joints, tiny moving dots, and a stippled, dusty look to the leaves. They thrive in the dry air many homes have.

The fix

Wipe the leaves down (avoid soaking the crown), raise humidity nearby without wetting the leaves, and treat with insecticidal soap or neem oil weekly until clear. Isolate it from other plants.

How to tell

Brown or black spots, often with a yellow halo, usually after the leaves were wet or the roots was overwatered.

The fix

Remove affected leaves, improve airflow, avoid getting water on the foliage, and let the roots dry more between waterings.
