Fertilization

Apply diluted balanced organic feed once monthly. Discontinue fertilization after early autumn to support hardening off for winter

Pruning
  • Deadhead spent flower clusters regularly to encourage extended blooming through late summer
  • Cut back all stems to ground level after the first autumn frost to prepare for winter dormancy
  • Thin overcrowded clumps in early spring to improve airflow and reduce disease risk
