Calcareous Water Sedge

Hybrid Sedge needs moderate watering and should not be allowed to dry out. Water approximately every 3–4 days during hot or dry conditions; this will prevent the soil from becoming completely dry. During cooler months, water every 5–7 days. Make sure that the soil never dries out completely. In order to ensure the right watering amount for Hybrid Sedge, use a soil moisture meter. This will help ensure that the plants receive the optimal amount of water for maximum health.

Hybrid Sedge is best grown in full sun. To thrive, this plant species requires 6-8 hours of direct sunlight every day. Exposure to too little light can cause stunted growth and poor flowering, while too much light may cause the leaves to yellow. It's best to provide this plant species with a consistent amount of consistent sunlight and to avoid direct exposure to intense midday sun. Ideally, Hybrid Sedge should receive morning light for several hours and then indirect light for the remainder of the day.

Hybrid Sedge (Carex aquatilis var. dives x var. kelloggii) should be pruned in early spring or early fall when the plant is growing rapidly. Pruning should remove any dead or damaged areas of the plant, as well as thinning out the shoots and stems to promote even, natural growth. Pruning should not involve any trimming of the foliage and should be done with sharp shears or scissors to ensure a clean cut. The amount of pruning should be minimal and should not involve removing more than 50% of the plant material.
