Maranta (Prayer Plant): Complete Care Guide

The maranta (Maranta leuconeura), known as the prayer plant, is one of the most fascinating foliage plants. Its leaves, marked with red or pink veins over green, fold upward at dusk like hands in prayer and open again at dawn. That movement, called nyctinasty, is a real spectacle.

The leaf movement

The leaves move thanks to water-filled joints at their base called pulvini. By day they open to capture light; at night they close. If your maranta stops moving, it's usually a sign of too little light or water stress.

Light

Ideal: medium to bright indirect light, but filtered.
Tolerates: some shade better than most plants.
Avoid: direct sun, which bleaches and scorches its decorative leaves.

Water quality: the key detail

The maranta is sensitive to chlorine, fluoride and the lime in tap water, which cause brown tips and edges.

Use filtered water, rainwater, or tap water left to stand for 24 hours.
Keep the soil slightly moist, never soggy.
Water at room temperature.

Humidity and temperature

It's tropical and needs high humidity to look its best. Below 50% you'll see dry edges. Raise humidity by grouping plants, using a humidifier, or a pebble tray with water. Keep it between 65 and 79 °F, away from cold drafts.

Why the leaves curl

This is the most common question about this plant:

Curled, dry leaves: lack of water or air that's too dry.
Curled leaves but moist soil: possibly too much light or overwatering.
Brown edges: almost always the lime or chlorine in the water.

Soil and repotting

Use an airy mix that holds some moisture: coco coir or peat with perlite. Repot every 1-2 years in spring. It's a good time to divide the plant and propagate it.
