Water during dry spells to ensure adequate moisture is available. It is important to avoid overwatering Slough Sedge as it will cause root rot.

Slough Sedge typically prefers full sunlight to partial sunlight for optimum growth. It requires at least 8 to 10 hours of sunlight each day for the duration of growth. The plant will benefit from additional sunlight during the active growing season, specifically from mid-morning up to an hour before sunset. To ensure optimal growth of Slough Sedge, avoid harsh midday sun and provide some protection from the hot sun in especially warm climates.

Slough Sedge, also known as Carex obnupta, should be pruned annually in late winter or early spring. Pruning should involve the removal of dead, brown or discolored foliage and any stems or roots that have become weak or spindly. Rejuvenation pruning can also be done in late summer or early fall to encourage dense, healthy growth. After pruning, Slough Sedge can be fertilized with slow-release fertilizer with a balanced ratio of nitrogen, phosphorus, and potassium in spring and midsummer.
