Specific Care for Dianthus petraeus (Rock Pink)

  • Soil: Prefers well-drained, rocky, or sandy soil, ideally with a neutral to slightly alkaline pH, to mimic its natural limestone habitats.
  • Watering: Exhibits good drought tolerance once established. Water regularly during the initial growth period, 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. If desired, apply a light, balanced fertilizer in early spring to encourage healthy growth without promoting excessive foliage at the expense of blooms.
  • Pruning: Deadheading spent flowers can promote further blooming. Trimming back the foliage in late autumn or early spring can help maintain the plant’s compact form and stimulate new growth.
