Fishbone Prayer Plant Care: Light, Water and Leaf Problems

The Fishbone Prayer Plant is Ctenanthe burle-marxii. Its pale green leaves have dark bands running out from the centre, with purple colouring underneath. It belongs to the same family as Maranta and the plants commonly sold as Calathea, but it is a distinct species.

Give it bright, indirect light and lightly moist, well-drained roots. There is no need to assume it is automatically easier than every Calathea or to chase a perfect leaf movement routine.

Find a bright, sheltered position

Choose a place with useful daylight, protected from strong direct sun. Leave space around the leaves rather than squeezing the plant against glass or a wall. Keep it away from cold draughts and hot, drying air from a radiator.

If the pattern looks less distinct, check exposure and overall growth before moving it. Faded or damaged foliage is not enough on its own to identify a light problem. For an unfamiliar plant, compare the botanical label as well as the leaf pattern; common names can overlap.

Keep moisture steady

Check the mix before watering. Aim for moisture through the root zone without keeping it saturated or allowing it to dry completely. Water thoroughly when needed, let the pot drain and empty any water collected in its outer container.

RHS advises keeping this species moist even in winter. That does not mean using the same amount or interval all year: a cooler, dimmer room usually means slower water use. A reminder can help you inspect the pot, but should not overrule what you find.

If leaves droop while the mix remains wet, check drainage rather than immediately watering again. Persistent wetness and dry roots can both leave a plant looking unhappy.

Make humidity and soil work together

Fishbone Prayer Plant prefers humid air. If your room is dry, measure it and consider a humidifier used according to its instructions. Repeated misting does not provide a lasting rise in humidity, and wet foliage is not the same as humid air.

Use a peat-free, moisture-retentive potting mix with good drainage and a container with holes. When roots crowd the pot, move up only a little. A very large container holds extra wet mix around a small root system.

Feed and divide during growth

Feed moderately while the plant is actively growing, following indoor-plant product directions. Reduce or pause feeding as growth slows. Do not use extra fertiliser to try to repair brown edges.

To make another plant, divide a healthy established clump in spring. Each section needs roots and growing shoots. Keep the new divisions sheltered from strong sun and check their smaller pots individually; they may use water differently from the original plant.

Check persistent leaf changes

Daily leaf movement is normal in this family, but it is not a pass-or-fail health test. For persistent curling or browning, first check moisture and drainage, then recent temperature or sun changes. Inspect stems and leaf undersides for pests, including mealybugs.

The Ctenanthe care guide explains the wider group's routine and troubleshooting. Use it alongside the species name, especially for identification: we have not verified a species-specific toxicology source for Ctenanthe burle-marxii, so we do not label it unconditionally safe for pets. Prevent chewing and ask a veterinarian or poison-information service about ingestion or symptoms.
