Care
Water management
Simple bur-reed is an entirely aquatic plant: it must remain submerged or in constantly moist soil. Install it in 10 to 30 cm of water depth in a pond or water garden. No additional watering is necessary since immersion is its natural environment.
Light exposure
Choose a sunny to partially shaded location for optimal growth. Simple bur-reed appreciates 4 to 6 hours of direct sunlight per day. In full shade, its growth weakens noticeably.
Substrate and growing medium
Plant it in rich soil, even slightly silty, typical of natural wetland areas. A mixture of garden soil and organic matter in a container facilitates establishment. Neutral to slightly acidic pH suits it well.
Nutritional input
Aquatic plants rarely benefit from fertilizer application in a well-balanced pond, thanks to nutrients from the water and substrate compost. Moderate feeding in spring can support flowering if the water is very clear.
Pruning and control
No pruning is strictly necessary. Simply remove dead or overgrown parts in late autumn or early spring. Control its spread by removing excess rhizomes to prevent it from dominating the pond.
Health and pests
Simple bur-reed is naturally resistant to disease in a healthy aquatic environment. In stagnant, nutrient-poor water, it may become weak. Maintain good water circulation and ecological balance to prevent any problems.
Did you know?
Simple bur-reed fascinates botanists with its peculiar inflorescences: male and female flowers develop on the same plant, but in separate spheres (spigule). This clever mechanism optimizes pollination by water in the aquatic environment, which earned it the scientific name Sparganium (from the Greek sparganon, meaning "ribbon"), referring to its long, narrow leaves.
Where to buy it
Best planted in spring or autumn, away from frost and heatwaves. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September, October.
