Dry air
Low humidity can cause leaf edges and tips to dry out, particularly on tropical plants such as Calathea, Alocasia and ferns.
Plant Problem Guide
Brown, crispy tips are one of the most common houseplant problems. They are usually caused by dryness, inconsistent watering or environmental stress rather than disease.
Look at the soil, watering pattern and growing environment together. More than one factor may be contributing.
Low humidity can cause leaf edges and tips to dry out, particularly on tropical plants such as Calathea, Alocasia and ferns.
Allowing the potting mix to become excessively dry repeatedly can lead to crispy tips, curling leaves and dry brown edges.
Moving between very dry and very wet soil can stress roots and make it harder for the plant to maintain healthy leaf growth.
Fertiliser salts or minerals from hard water can gradually collect in the potting mix and contribute to tip burn.
Compacted soil, damaged roots or unsuitable moisture levels can prevent the plant from taking up water effectively.
Radiators, heaters, cold draughts and sudden temperature changes can dry foliage or place the plant under stress.
Brown tissue will not turn green again, but it does not always mean the entire leaf needs removing.
If the rest of the leaf is healthy, the dry tip can be carefully trimmed with clean scissors. Follow the natural shape of the leaf and leave a very fine brown edge rather than cutting into healthy green tissue.
Removing the damaged tip is mainly cosmetic. The priority is identifying and correcting the cause so that new growth develops more successfully.
Brown tips alone rarely prove that a plant has root rot. Check the roots when other warning signs are also present.
