The prayer plant is one of the most charming houseplants you can grow — not just for its beautifully patterned leaves, veined in green, cream, and often striking red, but for what it does at night. As evening falls, a prayer plant folds its leaves upward, like a pair of praying hands, then opens them again at dawn. Add in the fact that it's pet-safe, and you have a plant that's as delightful as it is lovely. It does ask for a bit of attention — mainly humidity and the right water — but it's well worth it.

#Meet the prayer plant

Maranta leuconeura is a low-growing tropical plant from the Brazilian rainforest floor, closely related to the calathea (both are "prayer plants," and their care overlaps). Its oval leaves are patterned with intricate veins and blotches — the popular 'red' or 'herringbone' Maranta has vivid red veins against deep green. That famous nightly leaf movement, called nyctinasty, is driven by the day–night light cycle and is a real, visible response you can watch each evening.

#Light

Prayer plants are forest-floor plants that want bright, indirect light — never direct sun:

  • Best: bright, indirect light, a little back from a window.
  • Tolerated: medium light (patterns less vivid, slower growth).
  • Avoid: direct sun, which fades the patterns and scorches the leaves.

A north-facing window or a spot beside an east window suits them well.

#Watering: consistency and water quality

Prayer plants like their soil evenly, lightly moist — never bone dry, never soggy — and they're fussy about water quality, much like calatheas:

  • Water when the top centimetre or so of soil begins to dry — often every few days to weekly.
  • Use room-temperature filtered, distilled, or rainwater; fluoride, chlorine, and salts in hard tap water are a leading cause of brown, crispy edges.
  • Never let it sit in standing water, but don't let it dry out fully either.

Getting the water right — both consistency and quality — prevents most prayer plant problems. See watering houseplants.

#Humidity: essential

Like all rainforest-floor plants, prayer plants need humidity — ideally 50%+. In dry indoor air, especially with winter heating, they develop crispy edges and curling leaves. To keep one happy:

Misting gives only brief relief and can encourage leaf spotting, so a humidifier is far better.

#Warmth, soil, and feeding

Keep prayer plants warm (18–27°C) and away from cold drafts. Use a rich, moisture-retentive but well-draining mix (potting soil with coir and perlite) — see potting soil — in a pot with drainage. Feed with a diluted balanced fertiliser every 4–6 weeks in spring and summer, resting in winter; they're light feeders prone to salt build-up. See fertilising.

#Propagation

Prayer plants are easy to propagate by division — separate the plant into clumps at repotting, each with roots and leaves — or by stem cuttings taken just below a node and rooted in water or moist soil. See propagation. Their spreading, low habit makes division especially reliable.

#Common problems

Crispy brown edges. Low humidity, tap-water minerals, or inconsistent watering. Raise humidity, use filtered water, water evenly.

Curling leaves. Thirst, low humidity, or heat stress. Address moisture and humidity.

Faded patterns. Too much direct light. Move to bright, indirect light.

Yellowing leaves. Often overwatering; ensure the soil is moist, not soggy.

Leaves not folding at night. Usually a lighting issue (light at night) or an unsettled plant — ensure a normal day-night cycle and steady care.

Spider mites. Dry air invites them; keeping humidity up is both prevention and cure — see spider mites.

#Pet-safe and captivating

A major plus: prayer plants are non-toxic and safe for cats and dogs — a rare combination of dramatic, patterned, moving foliage and pet safety. See more options in pet-friendly houseplants.

#The bottom line

The prayer plant rewards a little attention with a lot of personality: stunning patterned leaves, pet safety, and that magical nightly fold. Give it bright indirect light (no sun), evenly moist soil with filtered water, warmth, and good humidity, and it'll open and close its praying leaves for you day after day. It's one of the most captivating — and genuinely pet-safe — plants you can bring into your home.

Frequently asked questions

How often should I water a prayer plant?
Keep the soil lightly and evenly moist — water when the top centimetre or so starts to dry, often every few days to weekly. Prayer plants dislike drying out completely and are sensitive to tap-water minerals, so use room-temperature filtered, distilled, or rainwater.
Why is my prayer plant getting brown, crispy edges?
Crispy brown edges are usually from low humidity, inconsistent watering, or minerals and chlorine in tap water — prayer plants are sensitive to all three. Raise the humidity, keep the soil evenly moist, and switch to filtered or distilled water.
Why isn't my prayer plant folding up at night?
The nightly folding (called nyctinasty) is driven by light cycles. If it isn't folding, the plant may be getting light at night, or it may be stressed or unsettled. Ensure it has a normal day-night light cycle and steady care; healthy, settled plants fold reliably.
Are prayer plants toxic to pets?
No. Prayer plants (Maranta) are non-toxic and considered safe for cats and dogs, making them a wonderful pet-friendly choice alongside their beautiful patterned, moving leaves.
