Specific Care for Dianthus bolusii (Cape Pink)

  • Soil: Thrives in well-drained, sandy, or gritty soil, preferring neutral to slightly alkaline pH levels.
  • Watering: Exhibits good drought tolerance once established. Water regularly during the plant’s first growing season to establish a deep root system, then reduce frequency, allowing the soil to dry slightly between waterings.
  • Sunlight: Requires full sun to flourish, needing at least 6-8 hours of direct sunlight daily for optimal growth and flowering.
  • Fertilizing: Minimal fertilization is needed. A light application of a balanced, slow-release fertilizer in early spring can encourage healthy growth without promoting excessive foliage at the expense of blooms.
  • Pruning: Deadheading spent flowers can promote further blooming. Light trimming of the foliage in late autumn or early spring can help maintain the plant’s compact form and stimulate new growth.
