🌱 How to Care for Hebe 'Magic Color' to Prevent Gray Mold (Botrytis Blight)?

💧 How to Water

Water regularly once the top layer of soil has slightly dried out, but never leave the soil waterlogged—hebes are sensitive to root rot. It is better to water at the base of the plant rather than on the leaves to reduce the risk of fungal diseases.

☀️ Lighting

It grows best in a sunny to lightly shaded spot. In areas with very hot summers, it appreciates afternoon shade to prevent scorching and fading of the variegated leaves.

🪴 Ideal Soil

Prefers light, well-draining soil enriched with compost. Heavy clay or permanently waterlogged soils are unsuitable—improve drainage by adding sand or perlite.
