🌱 How to Care for Blue Sage to Prevent Aphids?

💧 How to Water

Water every 7 to 10 days, allowing the top third of the soil to dry slightly between waterings. Reduce watering in winter when growth slows. Never leave the plant sitting in standing water as this promotes root rot.

☀️ Lighting

Place in bright indirect light or dappled shade — an east or west-facing window is ideal for indoor growing. Avoid intense midday direct sun, which can scorch leaves. Shorter days in autumn naturally trigger winter blooming.

🪴 Ideal Soil

Use a light, fertile, well-draining soil rich in organic matter. A mix of potting soil, humus, coarse sand or perlite, and peat works well. Maintain a slightly acidic to neutral pH between 5.6 and 6.5.
