Calathea 'Mia' Care: Maranta Family Needs—Moisture, Humidity, Low Light

Your Calathea 'Mia' (a Maranta/prayer plant) folds leaves at night—circadian rhythm. It needs a rainforest floor simulation.

Non-Negotiables

• Soil: Constantly moist, never wet/soggy. Water when top ½ inch dry; moisten top half of pot.
• Water: Distilled only. Tap water (fluoride, chlorine, salts) causes brown tips.
• Light: Low to medium, no direct sun. Thrives under artificial lights.
• Fertilizer: ⅓ strength liquid, only when needed. Flush pot 2 weeks before next feed.
• Humidity: High! Pebble tray, plant grouping, daily misting (distilled water).

Common Problem: Brown Tips/Edges

Caused by low humidity, overwatering, fluoride, or too much sun. Proper care prevents it.

Terrarium Star

Ideal for terrariums/dish gardens. Does NOT do well outdoors.

With distilled water, high humidity, and gentle light, your Calathea will stay stunning.
