In less humidity, leaves will start drooping, and the edges of leaves will start turning brown and crispy. 

To increase the humidity level in the surroundings, use a humidifier or gather all indoor humidity-loving plants in one location. As a result of grouping transpiration process of the plants will increase the humidity in the vicinity.

Calathea Yellow Fusion likes temperatures between 55 to 65℉ and will suffer greatly at temperatures below 65℉. Moreover, Yellow Fusion can’t tolerate drifts; therefore, it’s good to keep them away from cold and hot air drafts.

How often should I water Calathea Yellow Fusion?

Calathea Yellow Fusion loves to thrive in moist soil, so don’t let its pot soil dry. Please check the moisture through a moisture meter or use your finger to feel the moisture level in the potting soil. Keep an eye on plants’ freshness. If the leaves start dropping, the soil is dry and requires watering.

Usually, in the growing season (spring to summer), water your Yellow Fusion Calathea twice a week, while in winter, once a week will be sufficient. However, set the watering frequency to monitor the soil moisture level in all scenarios.

Avoid overwatering! It is harmful to plant health and makes it prone to fungal diseases. The yellowing of leaves is a clear indication of overwatering.

We recommend using filtered or distilled water; don’t use tap water as Calatheas are sensitive to tap water chemicals.
