Care Guide

Watering

Water every 7–10 days; increase frequency during extreme heatwaves

Fertilization

Diluted low-phosphorus fertilizer once every 6 weeks. Use fertilizer formulated for fynbos plants to prevent nutrient burn in low-nutrient adapted soils

Composted eggshell powder:Crush dried eggshells into fine powder; mix lightly into topsoil to boost calcium levels without overfertilizing nutrient-sensitive roots
Pruning
  • Prune spent flower heads immediately after blooming to encourage new growth and maintain plant shape
  • Thin overcrowded inner branches in early spring to improve airflow and light penetration
  • Remove dead or damaged wood annually to reduce pest and disease risk
