🌞 Sunlight:

🌱 Soil:
Prefers well-drained, fertile loam with a pH of 6.0–7.0. Avoid overly rich soil, which can reduce flowering.

  • Germinates in 7–14 days at 20–24°C

💧 Watering:
Water regularly during establishment. Once mature, water moderately—drought-tolerant and thrives in heat.

✂️ Maintenance:

  • Deadhead spent flowers to encourage more blooms and prevent unwanted seed formation
  • Pinch out seedlings at 30cm tall to promote bushier growth
  • Replace seasonally for best performance
