Brown leaf tips

Watering related

What it looks like

Leaf tips dry to brown, often with a thin yellow border. The rest of the leaf stays healthy.

Why it happened

Most often dry air. Also salts and chlorine from tap water, over-fertilising, or erratic watering that swings between dry and soaked.

What to do

1. Raise humidity — a pebble tray, or group plants together. 2. Let tap water stand for 24 hours, or use filtered water. 3. Flush the substrate thoroughly every few months to wash out salts. 4. Trim the brown tips just outside the healthy tissue — they will not turn green again.

How to prevent it

Keep a steady watering rhythm rather than swinging between a soaking and nothing. That swing is what causes the tips.
