Prayer Plant
Maranta leuconeura
Care level: Moderate
The prayer plant earns its name from a nightly ritual: as darkness falls, its leaves fold upward like hands in prayer thanks to a joint at the base of each leaf called a pulvinus, then unfold flat again each morning as light returns.
Prefers medium, indirect light; too much direct sun fades its patterned leaves.
Water
Keep soil evenly moist, watering when the top layer feels just dry, roughly weekly.
Humidity
Needs high humidity around 50-60%; leaf edges brown in dry air.
Soil
Light, well-draining potting mix rich in organic matter.
Temperature
Normal room temperatures, away from cold draughts.
Size
15-30cm tall and 15-60cm wide.

A rough guide based on window direction and typical daylight through the year. Window size, curtains and whatever stands outside matter just as much.
?Pet safety not confirmed
As a precaution, keep it out of reach of children and pets.
Did you know?
Maranta leuconeura's leaf-folding behavior, called nyctinasty, is driven by tiny motor cells in the leaf joints responding to light levels - it happens on a roughly 24-hour cycle even if the plant is kept under artificial light with no natural day-night change.
Care by Season
Spring
Resume regular watering and light feeding as new leaves emerge.
Summer
Keep humidity high and soil consistently moist; leaves fold up at night, which is normal.
Autumn
Slightly reduce watering as growth slows and stop feeding.
Winter
Water less often but never let it dry out completely; avoid cold drafts.
Growing & Maintenance
Soil and pot
A light, well-draining potting mix rich in organic matter, in a pot with drainage holes.
Fertilising
Feed lightly in spring and summer. Too much fertiliser burns the leaf tips.
Propagation
By dividing the rhizomes when you repot in spring.
Pests & Diseases
Common problems
Brown, crispy leaf edges
Most likely cause: Humidity below 50%, or minerals and fluoride in tap water.
What to do: Raise the humidity and water with filtered or rain water.
Faded leaf patterns
Most likely cause: Too much direct sun.
What to do: Move it to medium, indirect light.
Yellow leaves
Most likely cause: Overwatering.
What to do: Keep the compost evenly moist, not soggy, and make sure the pot drains.
Curled leaves
Most likely cause: Dry compost or dry air.
What to do: Water when the top layer feels just dry and raise the humidity.
Burnt leaf tips after feeding
Most likely cause: Too much fertiliser.
What to do: Feed more lightly and rinse the compost through with plain water.
Pests & Diseases
Spider mites
Signs: Fine webbing and speckled pale spots on leaves in dry conditions.
Treatment: Boost humidity, rinse leaves, and use insecticidal soap if needed. Check the undersides of the leaves and the crevices where the leaf stem meets the main stalk.
Mealybugs
Signs: White cottony deposits at leaf joints.
Treatment: Remove with an alcohol-dipped cotton swab and repeat weekly. Check the undersides of the leaves and the crevices where the leaf stem meets the main stalk.
Leaf edge browning
Signs: Crispy, brown leaf margins from low humidity or hard water.
Treatment: Increase humidity and water with filtered or rain water.
FAQ
Why does my prayer plant fold its leaves at night?
This is a natural daily rhythm called nyctinasty, not a sign of distress. The leaves rise and fold in low light and flatten out again once light returns each morning.
Why are my prayer plant's leaf edges turning brown and crispy?
Brown, crispy margins are usually caused by humidity below the 50-60% this species needs, or by minerals in tap water. Raising humidity and switching to filtered or rain water typically stops it.
How often should I water a Prayer Plant?
About once a week, when the top layer of compost feels just dry. Keep it evenly moist, and water less often in winter without letting it dry out completely.
How much light does a Prayer Plant need?
It needs medium, indirect light. Direct sun fades the leaf patterns.
How do I propagate a Prayer Plant?
By division. Split the rhizomes when you repot in spring, keeping roots and leaves on each piece.
How big does a Prayer Plant get?
About 15-30cm tall and 15-60cm wide. It stays low and spreads sideways.
