Cathedral Windows (Calathea Makoyana)

About Cathedral Windows

Cathedral Windows is a tropical foliage plant grown for its thin, oval leaves marked with pale green areas and darker feathered patterning. The contrast makes each leaf look detailed and layered, especially when light passes through from behind.

The leaf undersides add even more interest with their softer purple tone, and the plant’s daily movement gives it a distinct presence indoors. As evening approaches, the leaves lift slightly, then relax again by morning, which is why it is grouped with other prayer plants.

Over time, Cathedral Windows forms a dense clump of overlapping leaves that can hide the pot and soften a shelf, table, or plant stand. It works best as a statement foliage plant in rooms where direct sun is limited but warmth and humidity can be kept more stable.

How to Care for Cathedral Windows

Watering

Keep the soil consistently lightly moist. Water thoroughly when the top half inch (1–2 cm) begins to dry, then allow the excess to drain away completely.

Do not let the root ball dry out hard, because the leaves can droop and the edges may crisp. At the same time, avoid soggy soil, which can lead to yellowing and root problems. Room-temperature, low-mineral water is often the safest choice.

Sunlight

Cathedral Windows grows best in bright, indirect light. A position near an east- or north-facing window, or slightly back from a brighter window filtered by a sheer curtain, usually works well.

Direct midday sun can bleach and scorch the thin leaves, while very dim conditions can make growth slower and the markings less distinct.

Temperature

This plant prefers warm, stable temperatures, roughly 64–77°F (18–25°C). It dislikes cold drafts, sharp temperature swings, and hot dry air from heaters.

Short cooler nights are usually acceptable, but prolonged exposure below about 59°F (15°C) can stress the plant, especially if the soil is also too wet.

Humidity

High humidity helps Cathedral Windows keep clean leaf edges and better overall leaf quality. In dry indoor air, browning at the tips and margins is common even when watering is otherwise correct.

Grouping plants, using a pebble tray, or placing the plant in a naturally more humid room can all help. Lasting humidity support usually works better than occasional misting alone.

Soil

Use a rich organic, well-draining mix that can hold moisture without becoming dense or stagnant. A peat- or coco-based mix improved with compost, fine bark, and a little perlite is often a good fit.

The roots need both moisture and air, so drainage holes are essential. Any standing water left in the saucer should be emptied after watering.

Feeding

Feed lightly every 4–6 weeks during spring and summer with a balanced liquid fertilizer diluted below full strength. This usually supports steady new growth without stressing the plant.

Too much fertilizer can contribute to tip burn, so modest feeding is better than strong doses. When growth slows in winter, feeding should also be reduced or paused.

Grooming & Repotting

Remove yellowing or damaged leaves close to the base to keep the plant tidy and reduce stress on the rest of the foliage. Regular cleanup also helps the clump keep a fresher appearance.

Repot every 1–2 years, or when the roots begin to fill the pot and the mix starts to break down. Move up only one pot size at a time and refresh the soil so it stays airy and fertile.
