Hammer sedge

Also known as: Goose grass

Hammer sedge is a common perennial sedge found in damp meadows and grasslands, rough grassy places, open woodlands, and pond margins throughout spring, summer, and early fall. The leaves of this sedge are hairy (hence its other common name: Hairy sedge) which help distinguish it from other sedges.

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: Originating from moist meadows and woodlands, hammer sedge thrives in consistently moist environments. It prefers evenly moist soil and should be watered weekly. Mulching is beneficial for retaining soil moisture during the active growing season, especially in temperate climates.

Fertilize: Hammer sedge benefits from mulch or compost fertilization applied sparingly each spring, enhancing root strength and nutrient uptake. Avoid over-fertilizing to prevent root burn, and reduce fertilizer as seasons change. Evenly spread a thin layer around the base, avoiding stem contact for optimal growth.

Pruning: Hammer sedge, a tufted perennial sedge, should be pruned in early spring to promote healthy growth. Trim dead foliage, avoiding heavy pruning to maintain clump density. Pruning enhances vigor, prevents overcrowding, and requires sterilized tools to minimize disease. Consider natural growth for aesthetic appeal.

Propagation: Hammer sedge propagates through division of its dense clumps. Handle the fibrous roots carefully, ensuring each section has roots and top growth. Plant promptly at the same depth and maintain moist soil for establishment, preserving hammer sedge's desirable traits for ornamental or ecological uses.

Repotting: Repot hammer sedge every 2-3 years in early spring using larger, breathable pots to support growth. After repotting, use well-drained soil, moderate watering, and avoid over-saturation to prevent root rot, promoting lush, green vitality.
