Care Guide

  • Fertilize the plant every 4 to 6 weeks with a balanced, fertilizer during the growing season.
  • Watering needs: The plant prefers well-draining soil and should not be overwatered. Water the plant regularly to keep the soil evenly moist, but not waterlogged. In hot and dry conditions, water more frequently.
  • Maintenance needs: Deadhead the spent flowers regularly to encourage further blooming.
  • Pruning: Cut back to ground level in late fall when the plant turns yellow/brown.
