Care
Watering
Fen bedstraw appreciates constantly moist soil, even permanently wet conditions. Keep the substrate fresh without becoming waterlogged. During dry spells, increase your watering frequency, especially if the plant is in a pot.
Light exposure
Place fen bedstraw in partial shade or dappled light for optimal growth. It also tolerates full sun if the soil remains sufficiently moist. Choose a location sheltered from drying winds.
Soil
This plant loves moist, peaty soils or those rich in organic matter, with slight acidity. Improve your soil with compost or peat to recreate its natural habitat of marshes and wet areas.
Fertilizing
Fen bedstraw is undemanding. A moderate application of balanced fertilizer in spring is sufficient. In rich, moist soil, it often develops without supplementation.
Pruning and cleaning
Prune lightly in late winter or early spring to encourage compact branching. Remove dead or damaged parts. Regular cutting maintains a neat form and prevents legginess.
Diseases and pests
Fen bedstraw is generally very resistant. In soil that's too dry or poorly drained, watch for powdery mildew or root rot. Ensure good air circulation and avoid stagnant water.
Did you know?
Fen bedstraw, like all galiums, has tiny microscopic hooks on its stems and leaves that allow it to cling to clothing and animal fur for dispersal. In the past, this plant was used in dyeing to obtain red and pink tints, and it also served as wet fodder for livestock in the marshy areas of Europe.
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.
