Why does my houseplant have yellow leaves or brown tips?
Separate ageing leaves from root-zone problems, light damage, salts and pests. A practical sequence for investigating symptoms before choosing treatment.
Recognising leaf problems and pests
Yellow leaves, brown tips or fungus gnats? Choose guidance that helps you inspect the problem before treating it.
A leaf problem can make you reach straight for a treatment. Start by recording what you actually see: which leaf, what damage and what changed beforehand? The leaf guide helps organise those observations. The fungus-gnat guide addresses a specific problem and the checks that go with it.
Take a photo and record the date before changing several things at once. Later you can compare damage and new growth. Read the relevant guide for possible causes and next steps.
