🌱 How to Care for Russian Sage to Prevent Aphids?

💧 How to Water

Water regularly only during the first season after planting to help the plant develop a deep root system. Afterward, water sparingly but deeply—only when the soil has dried out significantly. Excess water leads to root rot.

☀️ Lighting

Provide a full sun location with at least 6-8 hours of direct sunlight daily. In the shade, the stems tend to stretch and flop over, and flowering is significantly reduced.

🪴 Ideal Soil

Plant in light, well-drained soil with a neutral to slightly alkaline pH. Avoid fertile, heavy, and overly wet soils—good drainage is crucial for winter survival.
