Fertilization

Apply diluted organic feed once monthly. Use low-nitrogen, high-phosphorus organic feed to support root development rather than foliage growth

Composted leaf mold tea:Steep fully composted hardwood leaf mold in water for 24 hours; dilute 1:20 for root drenching to avoid burning delicate roots and prevent odor buildup
Pruning
  • Remove yellowing or damaged foliage to improve airflow and redirect energy to root growth
  • Trim spent flower heads after blooming to prevent seed production and conserve root energy
  • Cut back dead aerial growth to ground level in late autumn after dormancy has set in
