Calathea Care

NurtureNudge care guide · Updated October 2026

Calatheas are the show-offs of the houseplant world: intricately patterned leaves that fold upward at night like hands in prayer, then unfurl again by morning. That daily movement is completely normal — it's called nyctinasty, and it's a sign your plant is healthy. What isn't normal is brown crispy edges, and calatheas are famous for them. The good news: brown edges are almost always a water-quality or humidity problem, both fixable.

Water: weekly, and mind the tap

Water your calathea about once a week, when the top inch of soil feels dry. It likes its soil evenly moist — never let it dry out completely, but never let it sit in water either. Think of it as the middle ground between thirsty ferns and drought-loving succulents.

Here's the calathea-specific part: it's fussy about tap water. Minerals and fluoride in hard tap water build up in the leaves and cause those signature brown, crispy edges. If your edges are browning despite good watering, switch to filtered water, distilled water, or rainwater — or at least let tap water sit out overnight before using it.

Light: medium to bright, never direct

Calatheas want medium to bright indirect light. They're one of the few statement plants that tolerate lower light, though they'll grow more slowly there. Direct sun is the enemy: it bleaches the intricate leaf patterns and scorches the leaves.

• Best: a few feet from an east or north window, or filtered light through a sheer curtain.
• Fine: a medium-light room away from windows — growth just slows down.
• Avoid: direct sun, which fades the patterns, and deep shade, which stalls the plant.

If the leaf patterns start looking washed out, it's getting too much light. Move it back a few feet.

Feeding and upkeep

Feed monthly in spring and summer with a balanced liquid fertilizer diluted to half strength. Calatheas are sensitive to salt buildup, so flush the soil with plain water every few months and skip feeding entirely in fall and winter.

Humidity matters as much as water: aim for 50% or higher. A humidifier nearby, a pebble tray, or a naturally steamy bathroom all work. Wipe the leaves occasionally with a damp cloth so the patterns stay vivid and the plant can breathe.

Troubleshooting: the five common problems

1. Brown, crispy leaf edges: The classic calathea complaint — almost always hard tap water or low humidity. Switch to filtered water and boost humidity.
2. Curling leaves: Underwatering or very dry air. Check the soil; if it's dry, give it a deep drink and raise the humidity.
3. Faded or bleached patterns: Too much direct light. Move it away from the window until the patterns look rich again.
4. Drooping leaves: Thirsty, cold, or both. Water it, and make sure it's not in a drafty spot or near a cold window in winter.
5. Yellow lower leaves: Overwatering. Let the soil dry a bit more between waterings and check that the pot drains freely.
