Calathea Orbifolia

This is almost always caused by low humidity or chemicals in tap water. Increase humidity to at least 60% using a humidifier, and switch to filtered water, rainwater, or water that has stood overnight. Brown edges cannot be reversed but new growth will be healthy.

Yes, Calathea orbifolia is non-toxic to cats, dogs, and children. This makes it one of the best choices for pet-friendly households that want a statement plant.

This is called nyctinasty or 'prayer movement.' The leaves fold upward at dusk and open in the morning, controlled by a tiny joint called a pulvinus at the base of each leaf stalk. It is completely normal and a sign of a healthy plant.

Misting alone is not enough to meet this plant's humidity needs. A humidifier is far more effective. If you do mist, spray the air around the plant rather than directly on the leaves, as water sitting on the foliage can cause fungal spots.

Filtered water, rainwater, or tap water that has stood overnight in an open container. Calathea orbifolia is sensitive to chlorine, fluoride, and dissolved minerals in tap water, which cause brown leaf edges. Distilled water also works but lacks minerals.

Ideally 60% or higher. Below 50%, you will almost certainly see brown leaf edges. A digital hygrometer helps you monitor humidity levels. A humidifier running near the plant is the most reliable way to achieve consistent humidity.

Curling leaves indicate stress — typically from low humidity, underwatering, cold temperatures, or too much light. Check each factor systematically. Curling is often the first warning sign before browning occurs.

A bathroom with natural light is actually one of the best spots for Calathea orbifolia. The naturally higher humidity from showers and baths closely mimics its tropical habitat. Just ensure the room has adequate indirect light and does not get too cold at night.
