Coastal cutty grass (Cyperus ustulatus)

Coastal cutty grass

As an emblem of scenic wetlands, coastal cutty grass got its peculiar name from its burnt-like tip, 'ustulatus' meaning scorched in Latin. The dark spikelets on its flower head, admired against vibrant green foliage, add a unique twist to any garden. However, beware of its invasive tendencies, as it can prolifically self-seed and usurp an area.

Water: Coastal cutty grass can thrive in overwatering conditions as it naturally grows in marshy environments. Maintain a steady water supply, especially in drip trays. Reduce watering during low temperatures to prevent root rot, ensuring some of the pot height remains dry.

Fertilize: Coastal cutty grass requires minimal fertilization; apply a standard-strength fertilizer monthly during active growth. It consumes less feed than similar-sized plants, making it an easy-care option for gardeners.

Pruning: Coastal cutty grass features tufted dark green foliage and thrives with spring pruning to enhance growth. Removing dead leaves and cutting older stems promotes tidiness and air circulation, lowering fungal disease risks. Clean, sharp tools are essential for healthy cuts and reduced plant stress.

Propagation: Coastal cutty grass can be propagated from seed in spring (13-18℃) using moist seed compost, or by division when overgrown. Cuttings can also be taken by trimming a healthy stem to 10 cm, placing it in water. Roots will develop, allowing re-potting as a new plant.
