Care Guide

  • Watering: Water regularly during the growing season, especially during hot and dry weather. Allow soil to dry slightly between waterings
  • Maintenance: Remove dead or diseased wood in the spring. Deadhead spent flowers to encourage more blooms
  • Pruning: Pinch back new growth in early summer to encourage branching and a fuller plant. Cut back the entire plant to about 12 inches in late fall or early spring to promote vigorous new growth the following season
  • (Optional):Fertilize with a balanced, slow-release fertilizer in early spring, just before new growth begins
