🌱 How to Care for Mealycup Sage to Prevent Leaf Spot?

💧 How to Water

Water deeply every 7–10 days, or when the top 2–3 cm of soil is dry. Avoid overhead watering to prevent fungal issues. Established plants are drought-tolerant but flower best with consistent moisture.

☀️ Lighting

Mealycup Sage demands full sun — at least 6 hours of direct sunlight daily. Insufficient light results in leggy stems and reduced flowering. In very hot climates, light afternoon shade is tolerable.

🪴 Ideal Soil

Plant in well-draining soil — sandy loam or garden soil amended with perlite or grit works well. Avoid heavy clay that retains moisture; this plant is prone to root rot in waterlogged conditions.
