Dwarf sedge (Carex pumila)

Dwarf sedge

Also known as: Sand sedge

Dwarf sedge is a grass-like, tufted herb. With its strong preference for sandy soil, it is found along coastal dune areas as well as around the sandy margins of coastal rivers and estuaries. Its seeds spread via water and wind. In coastal neighborhoods, dwarf sedge can become an urban lawn weed that outcompetes non-native turf grasses.

Interesting Facts

In 1754, Lin Nai founded the true sedge genus. True sedge is also one of the main components of the flora in China. It is the dominant grass species in the lowest forest layer in many areas. In some forests, the lower vegetation is mostly true sedge.

Water: Dwarf sedge prefers consistent moisture, thriving in humid conditions similar to its wetland origins. It has moderate drought tolerance and should be watered weekly. As a perennial herb, dwarf sedge is suitable for indoor and outdoor growth, requiring well-drained soil to avoid waterlogging.

Fertilize: Dwarf sedge thrives with semi-annual fertilization using a 2-inch layer of mulch or compost, enhancing soil fertility and moisture. Avoid direct foliage contact to prevent rot, and adjust fertilization seasonally—less in winter, more in summer—to support optimal growth.

Pruning: Dwarf sedge is a resilient, low-growing plant with dense foliage. Prune in early spring to encourage healthy growth by removing dead leaves and cutting back old stems. Proper pruning promotes air circulation, reduces disease risk, and enhances visual appeal without over-stressing the plant.

Propagation: Dwarf sedge is propagated through division, separating the root clumps carefully to avoid damage. This method ensures genetic consistency and promotes quick establishment. Plant in well-draining soil and provide regular watering and protection from extremes to support new growth acclimation.
