🌱 How to Care for Treasure Flower to Prevent Leaf Spot?

💧 How to Water

Water deeply every 7-14 days, allowing the soil to dry out completely between waterings. Gazania is very drought-tolerant — overwatering is the primary cause of root rot and fungal disease.

☀️ Lighting

Gazania rigens requires full sun — at least 6-8 hours of direct sunlight daily. Blooms close on cloudy days and at night, opening only in bright sunlight. Insufficient sun reduces flowering significantly.

🪴 Ideal Soil

Plant in well-draining sandy or loamy soil. Gazania tolerates poor and rocky soils. Avoid heavy clay or waterlogged conditions. A slightly acidic to neutral pH (5.5-7.5) is ideal.
