Why are my Calathea leaves curling?
Correspondingly, how often should you water Calathea?
Feed them room temperature water when the soil an inch (2.5 centimeters) below the surface is dry. The plants require regular watering during the summer months and less frequent watering during the colder months. You can periodically give the plants houseplant fertilizer [source: House of Plants].
Additionally, will Calathea leaves uncurl? A healthy calathea will slowly turn its leaves to catch ambient rays of sunshine; an unhealthy calathea will curl its leaves tightly to signify distress. Once you fix the problem, the leaves might even uncurl before your eyes. Move your plant out of the light.
Keeping this in consideration, why are my plants leaves curling inward?
SYMPTOMS: Edges of leaves curl inward and form a cup, even when the lights are off. The upper leaves are most affected. CAUSE: Heat stress causes rapid evaporation, so plants curl up to conserve moisture. PREVENTION: Monitor the temperature not just in the room, but around the upper surface of plants.
Should I mist my Calathea?
While some might appreciate being misted, take care not to mist them directly on the top of the leaves (or have moisture fall into the tightly raveled straws the new leaves make). Spray from the bottom up, and higher overall humidity is preferred over misting.
