Red Prayer Plant Care: Light, Water, Humidity, Problems

Give a red prayer plant bright indirect light, keep the soil evenly moist but never waterlogged, use water low in fluoride, and keep the air warm and humid. NC State Extension lists exactly those needs for Maranta leuconeura, and adds what it will not tolerate: direct sun, low humidity, low temperatures and cold drafts.

The red form is var. erythroneura, which Wikipedia calls the herringbone plant for its strong red veins on dark green leaves; NC State describes prominent red fishbone-patterned veins with dark, rabbit-track-like spots either side of the midrib. It is a small plant, 6 inches to a foot tall and spreading up to 2 feet (NC State), native to the tropical forests of Brazil (Wikipedia).

• Light: bright, indirect; a few feet from an east or north window.
• Water: keep evenly moist in spring and summer, a little drier in winter.
• Water quality: filtered, distilled or tap water left to stand for 24 hours (Rooted).
• Warmth: never below 59 F (15 C); 70 to 81 F by day is ideal (Wikipedia).
• Humidity: high; group it with other plants or run a humidifier.

The leaves lie flat by day and fold upright at night, which is where the name comes from. Wikipedia calls this a daily rhythm known as nyctinasty, and NC State describes the leaves folding to a perpendicular 'prayer' position after dark. It is normal and a sign the plant is alive and responsive. A plant whose leaves stay folded or curled during the day is a different matter; see the problems below.

Somewhere bright but out of direct sun, warm, humid and draft-free. NC State says direct sun fades the leaf colours and lists the plant as tolerating low to medium light, while Rooted's care notes say direct light burns the leaves. A few feet back from an east or north window, or in a bathroom with a window, fits. Keep it away from heating vents, air conditioners and cold glass in winter: NC State lists cold drafts and low humidity among the conditions it cannot tolerate, and Wikipedia gives 59 F (15 C) as the minimum.

NC State's rule is evenly moist through the growing season and less in winter, in a well-drained mix so the roots do not rot. Rooted waters about weekly; treat that as a starting point and check the top of the mix first.

Water quality matters more than for most houseplants. NC State warns that high fluoride in water, and over-fertilising, burn the leaves; Rooted recommends filtered or distilled water, or tap water left to stand for 24 hours, to avoid tip burn from chlorine and minerals. NC State's warning is specifically about fluoride, so if the tips still burn with standing tap water, switch to distilled water.

High humidity is the other requirement. Both NC State and Rooted suggest a tray of wet pebbles; Penn State Extension (updated 13 December 2024) found that pebble-tray moisture diffuses into the room with almost no effect, and that grouping plants, a humidifier or a cloche work better. Winter heating can drop indoor humidity below 30% (Penn State), which is when brown tips usually appear.

Feed lightly. Rooted uses a half-strength balanced liquid fertiliser twice a month, and NC State warns that over-fertilising burns the leaves, so err on the weaker side and stop in winter. Rooted repots every two years into a slightly larger pot. To make more plants, divide the clump at repotting: NC State lists rhizomatous division as the propagation method. Rooted notes that in good conditions it may produce tiny purple or white flowers.

• Curling leaves. Underwatering (Rooted). Check whether the mix has dried right through.
• Brown, crispy tips. Low humidity (Rooted), or fluoride and fertiliser burn (NC State). Change the water before anything else.
• Yellowing leaves. Overwatering (Rooted); NC State lists root rot in poorly drained soil.
• Faded colour or scorched patches. Too much direct sun (NC State, Rooted).
• Fine webbing or cottony spots. NC State reports no serious insect problems but notes occasional spider mites and mealybugs. Fig Boss notes that spider mites favour low humidity, so raising humidity helps here too. See spotting and treating plant pests.

For yellow leaves on any plant, our yellow leaves guide sorts causes by where on the plant the yellowing starts.

Wikipedia describes two naturally occurring varieties with the Royal Horticultural Society's Award of Garden Merit: erythroneura, the red herringbone plant, and kerchoveana, called rabbit's foot, with dark blotches between the veins and no red. NC State's common names for the species include rabbit tracks and cathedral windows as well as red-veined prayer plant, which is why labels vary.

Calathea is a close relative in the same family, Marantaceae, and is often sold under the prayer plant name too. The ASPCA's 'Prayer Plant' entry illustrates the mix-up: it lists the common names Prayer Plant, Maranta and Red Veined Prayer but files them under the scientific name Calathea insignis, and marks the plant non-toxic to cats, dogs and horses. Calathea itself is also listed non-toxic; see our calathea pet page.

The practical ones are specific. It is on the ASPCA non-toxic list, so it is one of the patterned houseplants you can keep where a cat or dog can reach. It stays small, under a foot tall per NC State, so it fits a shelf or desk. NC State says it tolerates low to medium light, as long as it is out of direct sun. And it moves: the leaves fold up every evening (NC State, Wikipedia). Claims that it cleans the air of a home are not supported by the sources we checked, and our low maintenance indoor plants guide explains why houseplants in general do not measurably purify room air.

Research and drafting for this page were done with the help of AI, and every figure was then checked line by line against the sources listed at the end of the page. Sources were opened on 2026-09-25. Where sources disagree, we give each figure with its source rather than picking one. The Spruce's prayer plant guide ranked in the top three for this search but could not be opened, so nothing here is taken from it. If you find a mistake, tell us and we will correct it.
