Care Guide

Watering

Water deeply once every 1-2 weeks during extended dry spells

Fertilization

Apply a slow-release balanced fertilizer once in early spring. Use sparingly to avoid excessive, leggy growth that disrupts the compact mound shape

Eggshell powder topdressing:Crush dried eggshells into a fine powder; sprinkle lightly over the soil surface in early spring to boost soil calcium levels and improve drainage
Pruning
  • Trim lightly in early spring to maintain the desired rounded shape
  • Remove any dead, damaged, or discolored branches to improve airflow
  • Avoid heavy pruning, as new growth may not match the mature silvery-blue foliage color
