🌱 How to Care for Wild Thyme to Prevent Grey Mould?

💧 How to Water

Allow the soil to dry out completely between waterings. Water approximately every 14 days in summer, less frequently in winter. Overwatering is the most common cause of plant death — Wild Thyme prefers drought over moisture.

☀️ Lighting

Requires at least 6–8 hours of direct sun per day. Full sun promotes the densest growth and strongest aroma. In partial shade, flowering is significantly reduced, and the plant becomes thin and leggy.

🪴 Ideal Soil

Use light, sandy or gravelly, well-draining soil with a pH of 6.5–7.5. Avoid heavy clay soil. Lean soil is preferred over nutrient-rich — too much nutrient results in low aromatic intensity. Add gravel or perlite if needed.
