Expert tips
The key tip
Water with non-calcareous water (filtered or rainwater) once or twice a week: limescale causes leaf yellowing and stomatal blockage. Maintain stable ambient humidity by grouping pots together or placing the pot on a bed of water beads, as sharp changes in humidity snap petioles and create brown veining.
The common mistake
Using hard tap water directly: most Marantas don't die from lack of water, but from mineral buildup that blocks root absorption and causes mottled or necrotic leaves.
The pro's trick
Watch the leaf movement: they close in late afternoon if watering is correct. If they stay open at night or barely close, they're lacking humidity — adjust immediately before the veins brown.
Seasonal watch
In winter, drastically reduce watering and increase ambient humidity simultaneously: heating dries the air, roots slow down, and excess water stagnates. This is when most rot occurs. Test the substrate with your finger: it should be moist, never soggy.
Care
Watering
Keep the substrate consistently moist without waterlogging: water as soon as the surface begins to dry. Favor soft, filtered, or rainwater, as this plant dislikes hard water. In winter, reduce watering frequency slightly while ensuring the soil never dries out completely.
Light and Exposure
Place the plant in bright, indirect, filtered light: it appreciates brightness but fears direct sun rays that can scorch the leaves. Avoid overly dark spots that would slow its growth. A distance of 3 to 6 feet from a north or east-facing window is ideal.
Soil and Repotting
Use a substrate rich in organic matter, light and aerated, such as indoor plant potting mix to which you add perlite or fine bark. Repot every 2 years in spring, ideally in a slightly larger pot with drainage holes.
Fertilizer and Nutrition
Apply diluted indoor plant fertilizer every 15 to 20 days during the growing season (April to September). In fall and winter, reduce or stop applications. A balanced formula (NPK type 10-10-10) works well for this species.
Pruning and Cleaning
Prune lightly after winter to maintain a compact shape and stimulate branching. Remove yellowed or damaged leaves over time. Gently cleaning the leaves with a damp cloth aids photosynthesis and limits dust buildup.
Common Pests and Diseases
Watch for spider mites and mealybugs, favored by dry air: increase humidity with regular misting. Excess water causes root rot and fungal diseases: ensure optimal drainage and air circulation. Isolate any infested plant.
Did you know?
Maranta leuconeura earns its nickname "Prayer Plant" because its leaves fold upright and close at night, forming a sort of praying hands, then unfold in the morning—this nyctinastic movement is fascinating to observe and entirely natural. The brick-red patterns and white veins of its oval leaves give it a particular ornamental prestige highly prized by indoor plant collectors since the nineteenth century.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
