Composted grass clipping tea：Steep fully composted grass clippings in water for 3 days; dilute 1:20 before applying to root zones to avoid nutrient burnPruning
- Mow or trim clumps to 10 cm height in late autumn to control spread and prevent self-seeding
- Remove seed heads before maturity to limit invasive potential
- Thin dense clumps every 2–3 years to improve airflow and reduce disease risk
