Brown tips or edges on otherwise healthy leaves are a very common houseplant problem. Unlike yellowing, which often indicates overwatering, brown tips are more likely to be a cultural issue — something about the environment or care routine.
Low Humidity
The most common cause for tropical plants. Brown, dry, crispy tips are the classic symptom of air that's too dry. Central heating is a major culprit in winter.
Fix: Increase humidity with a humidifier, grouping plants, or placing in a bathroom.
Inconsistent Watering
Plants that swing between very dry and very wet develop brown tips as the root system is stressed.
Fix: Establish a consistent watering routine based on soil moisture, not a fixed schedule.
Fluoride or Chemical Sensitivity
Some plants (spider plants, peace lilies, dracaenas) are sensitive to fluoride in tap water and to mineral salts in fertiliser. Brown tips appear gradually.
Fix: Use filtered, rainwater, or leave tap water overnight. Flush the soil periodically.
Overfertilizing
Excess fertiliser salts accumulate in the soil and burn root tips, causing leaf tips to brown.
Fix: Flush soil thoroughly with water. Hold off on feeding for 2–3 months.
Physical Damage
Brushing past furniture, pets, cold windows — physical damage appears as brown marks (not necessarily tips).
Fix: Identify and remove the source of damage.
Note
Once a leaf tip has browned, it won't turn green again. Trim the brown with scissors following the natural leaf shape. Address the underlying cause to prevent new browning.
