Care Guide

Watering

Keep consistently moist, watering deeply when the top inch of soil feels dry

Fertilization

Apply a balanced slow-release fertilizer as new growth emerges. Feed lightly; excessive fertilizer can cause leggy growth and weak stems.

Compost Tea:Steep aged compost in water for a few days, strain, and use the liquid to water the base of the plant. Avoid applying directly to the foliage.
Pruning
  • Cut back foliage to the ground in late autumn or early spring after it dies back;
  • Remove spent flower stalks to tidy the plant's appearance, though seed heads can provide winter interest;
  • Divide clumps every 3-4 years in early spring if they become overcrowded or lose vigor.
