🌱 How to Care for Floss Flower to Prevent Aphids?

💧 How to Water

Water at the base of the plant approximately once a week, providing about 2.5 cm (1 inch) of water. Ageratums have shallow roots and can wilt quickly in dry spells, so keep soil evenly moist but never waterlogged. Always water at ground level to keep foliage dry and prevent fungal diseases.

☀️ Lighting

Plant in a location that receives at least 6 hours of direct sunlight daily for the best flower production. In regions with intense summer heat, light afternoon shade will protect the foliage from scorching without significantly reducing bloom quantity.

🪴 Ideal Soil

Use rich, well-draining soil amended with compost or organic matter. Ageratum is adaptable to a wide pH range (6.0–7.5) and is not fussy about soil type as long as drainage is good. Mulching around the base helps retain moisture and keeps roots cool.
