Sedge

Carex maritima x

Sedge (Carex maritima x) is a grass-like, flowering plant native to coastal habitats. It has a low, branching growth habit and can reach a height of .5 to 1 m. Its narrow, grass-like leaves grow in a round clump and are a light green to blue-green colour. The plant blooms in spring and summer with greenish-brown spikes of small flowers. Sedge can tolerate a wide range of soil types and conditions including sand, clay, soil with high salt content and is tolerant of drought. Its deep root system encourages drainage and helps to stabilize shorelines. The plant provides cover and food for wildlife and habitats along the shoreline.

watering

Sea Sedge should be watered moderately; it likes consistently moist soil. Water the Sea Sedge whenever the top inch of soil feels dry to the touch. Water deeply, then wait until the soil partially dries out before watering again. Avoid letting the soil become overly wet or soggy as this can damage the plant’s roots. To ensure the Sea Sedge receives enough moisture during periods of high heat and wind, provide it with an occasional deep soaking.

sunlight

Sea Sedge (Carex marina) requires an average of 8 hours of sunlight each day during the warmer months to survive and thrive. It prefers bright, indirect sunlight with some periods of direct sun exposure in the morning or evening. This species does best when grown in well-drained soil with ample organic matter. For optimal growth it should be exposed to an environment that is consistently moist but not overly wet. Sea Sedge is a salt tolerant plant, meaning that it can tolerate a certain amount of salt in the air or soil. It also does best in a location where it receives protection from strong winds.

pruning

Sea Sedge should be pruned lightly in early spring, right before new growth begins to appear. Trim the plant down to 1-2 inches above the soil line. Avoid pruning when the plant is flowering or fruiting, as this will remove the seed heads and result in fewer flowers and fruits the following year. To promote bushier growth, remove the oldest stems by pruning them down to the ground. Pruning Sea Sedge can also be done throughout the growing season to remove dead or unsightly shoots.
