🌱 How to Care for Cockscomb to Prevent Damping Off?

💧 How to Water

Water every 2-3 days directly at the base without wetting leaves or flowers. Keep soil evenly moist but never waterlogged. During intense heat, daily watering may be needed. Avoid evening irrigation to prevent fungal diseases.

☀️ Lighting

Cockscomb requires full sun — at least 6 to 8 hours of direct sunlight per day. In partial shade, flowers lose vitality and the plant becomes leggy. In extreme heat regions, light afternoon shade can be beneficial.

🪴 Ideal Soil

Use light, fertile, well-draining mix with pH between 6.0 and 7.2. Incorporate mature organic compost and perlite to ensure good drainage. Avoid compacted clay soils, which promote root rot.
