Pet safety unknown

Most likely cause

Dry air (low humidity)

How to tell

Just the very tips and edges go brown and papery while the rest of the leaf is fine. This is most common in winter with the heating on, and air plant prefers 50–70% humidity.

The fix

Give it an extra soak each week while the heating is on, and keep it away from radiators.

Other possible causes

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

Too little soaking

How to tell

Air plant dries out between soaks faster than most people expect since it has no soil reservoir, so the tips crisp first.

The fix

Soak it fully once a week (twice in a hot, dry room) rather than relying on misting alone.

Hard-water minerals

How to tell

Tips brown even though it gets regular soaks, and a pale film may show on the leaves. Hard tap water leaves minerals behind.

The fix

Soak it in rainwater or distilled water instead of hard tap water.

Fertilizer burn

How to tell

Tips brown within a week or two of feeding. Air plants need only a very weak dose in their soaking water.

The fix

Rinse it in plain water, and feed at a quarter of the label strength no more than once a month.

Too much direct sun

How to tell

Dry brown patches or scorched edges show up where strong sun hits the leaf. Air plant wants bright light and some direct sun.

The fix

Filter the harshest midday sun with a sheer curtain for a few weeks, then reintroduce the sunny spot gradually so the leaves can harden off.
