Crispy leaves usually indicate underwatering, low humidity, or excessive heat. When plants don’t get enough water, leaves dry out and turn brittle.
Dry indoor air, especially in winter or near heaters, can also cause crisp edges. Sunburn from direct sunlight can make leaves crispy as well.
To fix it, increase watering frequency, raise humidity with a humidifier or pebble tray, and move the plant away from hot or sunny spots.
A humidifier for tropical plants and monitoring soil moisture prevents further damage. Removing badly damaged leaves helps redirect energy to healthy growth.
