🌱 How to Care for Egyptian Papyrus to Prevent Rust?

💧 How to Water

Keep roots permanently wet or submerged. Place the pot in a tray of standing water or directly in a pond/water feature. In hot climates, daily watering may be necessary for container-grown plants. This plant cannot tolerate drought under any circumstances.

☀️ Lighting

Requires full sun — at least 6 hours of direct sunlight daily. Indoors, place in the brightest south-facing window available. Insufficient light causes weak, etiolated stems and loss of the plant's impressive upright form.

🪴 Ideal Soil

Prefers heavy, loamy to clay soil rich in organic matter, pH 6.0–8.0. In containers, use a heavy potting mix with added clay or garden loam. Can also be grown directly in water without substrate. Good drainage is not needed — waterlogged conditions are preferred.
