Care
Regular and consistent watering
Water dropwort appreciates consistently moist soil, even waterlogged conditions. Keep the soil moist during the growing season and avoid complete drying out. In containers, water frequently during the growing period and reduce slightly in winter.
Light and exposure
Position it in full sun or partial shade for optimal growth. It tolerates lightly shaded areas well. Direct sun exposure promotes more abundant flowering.
Moist and rich soil
This plant requires fertile, well-drained but constantly moist soil. A mixture enriched with organic matter (compost, peat) is ideal. It thrives in slightly acidic to neutral soils.
Moderate nutrition
Apply balanced diluted fertilizer once or twice monthly during the growing season (spring-summer). Excess nitrogen promotes foliage at the expense of flowering.
Cutting back and maintenance
Remove dead stems and faded flowers to stimulate branching and extend flowering. In late autumn, cut the plant back to ground level to prepare it for winter dormancy.
Problem prevention
Excellent hardiness and rarely affected by pests. However, ensure good drainage and sufficient air circulation to prevent fungal rot from excessive stagnant moisture. Inspect foliage regularly.
Did you know?
Water dropwort gets its name from the Greek 'oinos' (wine) and 'anthos' (flower), though this plant is better known for its fistulous (hollow) stems than for any oenological properties! Historically, it was used in traditional European herbal medicine, particularly for its supposed diuretic virtues in the wet areas where it naturally grows.
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.
