Care Guide

Watering

Water occasionally during prolonged dry spells to prevent wilting

Fertilization

Apply a diluted, low-nitrogen feed once at the start of growth. Fertilization is optional, as it grows well in low-nutrient soils

Composted coffee grounds tea:Use fully composted coffee grounds diluted 1:30 with water for a mild, slow-release feed; avoid raw grounds to prevent soil acidity spikes
Pruning
  • Mow or trim to a height of 5–10 cm to control spread in lawns or garden beds
  • Remove mature seed heads before they disperse to prevent self-seeding
  • Thin overcrowded tufts to improve airflow and reduce competition for resources
