Expert tips
The key tip
Plant it with its feet constantly submerged or in waterlogged soil: it's an aquatic plant. Provide regular nutrients because poor flooded soil doesn't nourish it enough.
The common mistake
Forgetting that at -5°C, papyrus freezes: in cold climates, grow it in a movable pot that you bring indoors before the first frosts.
The pro's trick
Multiply it simply by detaching the rosettes from the mother stems and replanting them in shallow water (10-15 cm).
Care
Watering
Papyrus is a semi-aquatic plant that requires very regular watering. Keep the soil constantly moist or place the pot in a saucer of water that you refill daily. During the growing season (spring-summer), water must remain abundant. Slightly reduce humidity in winter, but never let the soil dry out completely.
Light Exposure
Place your papyrus in full sun for optimal growth and a beautiful shape. It tolerates partial shade, but risks becoming leggy and losing vigor. About 6 to 8 hours of direct sunlight per day are ideal. Indoors, choose a very bright window facing south or west.
Soil and Substrate
Use a rich organic soil mix: horticultural potting soil blended with heather soil or well-decomposed compost. Papyrus appreciates a light but nutritious substrate. Moderate drainage is acceptable since the plant loves constant moisture; soil rich in peat or organic matter works very well.
Fertilizer and Nutrition
Apply a balanced fertilizer or one slightly rich in nitrogen once or twice a month during the growing period (March to September). You can use diluted liquid fertilizer or regular compost application. In winter, reduce or stop fertilizing altogether.
Pruning and Maintenance
Remove dry or damaged stems at soil level with clean pruning shears. Remove faded flower heads to encourage new shoots. Little formal pruning is necessary; the plant naturally grows into a dense clump. Regularly dust the leaves lightly to optimize photosynthesis.
Diseases and Pests
Indoors, papyrus can be affected by spider mites in dry conditions; maintain high ambient humidity. Aphids and mealybugs are possible but rare. Regularly check for yellow or brown spots indicating stagnant excess moisture or poor drainage.
Did you know?
Egyptian papyrus provided the most famous writing material of antiquity: the ancient Egyptians made a kind of paper from Cyperus papyrus stems by crisscrossing and compressing them. This innovation revolutionized knowledge preservation and the transmission of pharaonic, religious, and administrative texts for more than three millennia!
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.
