🌱 How to Care for Baby's Breath to Prevent Southern Blight?

💧 How to Water

Water deeply but infrequently, allowing the soil to dry out between waterings. Use the soak-and-dry method — overwatering leads to root rot. Established plants are drought-tolerant and prefer dry conditions.

☀️ Lighting

Requires a minimum of 6 hours of full direct sunlight daily for vigorous flowering. Tolerates light afternoon shade in very hot climates, but too much shade leads to leggy growth and fewer blooms.

🪴 Ideal Soil

Plant in well-drained, loamy or sandy soil with a slightly alkaline pH (7.0–8.0). Avoid clay-heavy or waterlogged soils. Adding lime to acidic soil improves performance significantly.
