Water your Green Prayer Plant (Maranta leuconeura var. kerchoveana) weekly, keeping the soil lightly moist but never soggy. That is the short answer: check the soil first, and water when the soil tells you to, not because a particular day of the week has arrived. Prayer plants have no water storage at all, so the gap between 'lightly moist' and 'dry' is short — but the gap between 'lightly moist' and 'soggy' is where the damage happens.
The Green Prayer Plant, Maranta leuconeura var. kerchoveana, is the original prayer plant: oval leaves with dark blotches down the centre, folding up at dusk and opening at dawn. It spreads by creeping stems that root where they touch the soil, so the plant's feeding roots are shallow — keep the top layer of mix lightly moist and the plant stays happy.

How to check whether it needs water
Push your finger about an inch into the potting mix: if it feels lightly damp, like a wrung-out sponge, wait; if the top inch feels dry, water. Check in two or three spots, because the side facing the window dries first and the centre of the root ball dries last. Never judge by the surface alone — the very top can look dry while an inch down is still moist, and for a prayer plant that top inch is where most of the feeding roots live.
A moisture meter is especially useful for this group, because the difference between "lightly moist" and "soggy" is hard to feel with a finger until you have done it a few times. Aim for the middle of the meter's moist range, not the wet end. Pot weight helps too: lift the pot just after watering, then again a few days later. A pot that still feels heavy is not ready, however dry the surface looks. Our watering calculator can give you a starting point for your pot size.
Watering through the seasons
Green Prayer Plant grows in spring and summer and slows down in autumn and winter, and its thirst follows that rhythm. In the growing season, when new leaves are unfurling, it will need water close to weekly, and sometimes a little more often in a warm, bright room. In winter, growth slows and the same pot may take ten days or more to dry to the right point — and cold, wet soil is the real danger in winter, because roots sitting in cold, soggy mix rot quickly. Keep the plant in its 65–80°F comfort range, away from cold windows and draughts, and stretch the interval rather than watering on a calendar.
Humidity matters as much as the calendar here: Green Prayer Plant likes high humidity, and in dry winter air with the heating on, the leaves lose moisture faster even though the soil is drying more slowly. That combination — dry air, damp soil — is what causes crispy brown edges even in a well-watered plant, so run a humidifier or group plants together rather than watering more often to compensate.
What changes how often you water
Pot, light, humidity and temperature change the interval more than anything else. A small pot dries far faster than a large one, terracotta dries the mix faster than plastic or glazed ceramic, and a light, airy mix with bark and perlite dries faster than dense, peat-heavy soil. A plant in medium indirect light uses water steadily, while the same plant in a dim corner grows slowly and the soil stays wet far longer — and Green Prayer Plant likes high humidity, which slows evaporation from the soil and stretches the interval a little.
The potting mix matters more for this group than for most houseplants. Prayer plants want a mix that holds moisture but still drains freely: a peat- or coir-based mix with perlite and a little bark works well. A dense, heavy mix stays wet in the middle while the top looks dry, which tempts you to water again — and that is how roots rot. If your plant is still wet a week after watering, the mix is probably too heavy, not the schedule too generous.
Signs of overwatering
Overwatering is the most common way to kill a Green Prayer Plant, and it is almost always a watering-too-often problem rather than a watering-too-much-at-once problem: the soil stays wet, air is pushed out of the mix, and the roots suffocate and rot. The data lists these problems for this plant: brown leaf edges (low humidity); curling leaves (underwatering); faded leaves (too much direct sun).
Yellow leaves — especially lower, older leaves turning yellow — are the classic first sign, and the data lists yellow leaves from overwatering as a problem for this plant where applicable. Soft, dark stems, a musty smell from the soil, and leaves that yellow and drop in quick succession point to root rot. Fungus gnats hovering around the pot are another giveaway: they breed in soil that never dries.
If you catch it early, stop watering and let the pot dry out until the top inch is dry, then water lightly. If the roots are soft and dark, cut away the rotted roots and repot in fresh, dry, free-draining mix, in a pot with drainage holes.
Signs of underwatering
Underwatering shows up fast in this group, because these plants have no water storage — no thick leaves, no swollen trunk — and their leaves are the first thing to suffer. The first sign is leaf curling: the leaves roll inward along their length to reduce the surface losing moisture. Next come brown, crispy leaf edges and tips, drooping leaves that stay folded during the day instead of opening, and older leaves yellowing and dropping.
The data flags curling leaves from underwatering or low humidity for this plant, and that curling is your best early warning — a curled plant that is watered promptly usually uncurls within a day. To revive a dry plant, water thoroughly until water runs from the drainage holes, and if the mix has shrunk away from the sides of the pot, stand the pot in a basin of water for twenty minutes so the mix rehydrates properly. Then return to checking the soil and watering when the top inch is dry, rather than watering little and often.
How to water it properly
When the soil check says it is time, water thoroughly: pour slowly and evenly until water runs freely from the drainage holes, then empty the saucer so the plant never sits in standing water. A thorough soak is better than frequent sips, because sips wet only the top layer and leave the deeper roots dry. Bottom watering works too — stand the pot in a few centimetres of water for fifteen to twenty minutes, then let it drain — and it is useful when the mix has dried out or you want to keep water off the leaves.
Water type matters more for prayer plants than for most houseplants: they are sensitive to the salts, chlorine and fluoride in tap water, which is one reason the data lists crispy brown edges from tap-water salts for this group. Use rainwater, distilled water, or tap water left out overnight, at room temperature — very cold water can shock tropical roots. Top-water occasionally even if you usually bottom-water, to flush salts out of the mix. Our humidity and temperature checker can tell you whether your room suits this plant.
Frequently asked questions
Can I water my Green Prayer Plant on a fixed weekly schedule?
No — use the soil, not the calendar. Weekly is the average, but a warm, bright room in July and a cool, dim room in January are different worlds. Check the soil before every watering, and water when it is dry to the depth this plant needs.
How do I know if I have overwatered my Green Prayer Plant?
Check the soil first: if it is wet and the leaves are yellowing, soft or dropping, overwatering is the likely cause. The plant's listed problems are brown leaf edges (low humidity); curling leaves (underwatering); faded leaves (too much direct sun). Let the pot dry out and check the roots for soft, dark, rotted sections if several leaves yellow at once.
('### Should I mist my Green Prayer Plant instead of watering it?\n\nNo. Misting wets the leaves for a few minutes and does almost nothing for the roots, which is where the plant drinks. Green Prayer Plant likes high humidity — a humidifier or a pebble tray helps far more than misting, and wet leaves can invite fungal problems.',)
('### Can I bottom-water my Green Prayer Plant?\n\nYes. Stand the pot in a few centimetres of room-temperature water for fifteen to twenty minutes, then lift it out and let it drain fully. Do not leave it standing in water for hours, and still top-water occasionally to flush salts out of the mix.',)
Why are the leaf edges of my Green Prayer Plant turning brown and crispy?
Usually low humidity or salts in tap water — the data lists crispy brown edges from low humidity or tap-water salts as a problem for this plant. Raise the humidity with a humidifier, switch to rainwater or distilled water, and keep the soil lightly moist. Brown edges will not heal, but new growth will come through clean.
