🌱 How to Care for Mexican Bush Sage to Prevent Aphids?

💧 How to Water

Water about once a week while it gets established and during hot, dry weather, letting the top soil dry between waterings. Once established it handles short droughts. In winter water very little: soggy cold soil rots the roots.

☀️ Lighting

Full sun, at least six hours of direct light a day, gives the most flowers. In very hot climates it accepts some afternoon shade, but in deep shade it gets floppy and blooms less.

🪴 Ideal Soil

Any well-drained soil, from sandy to loamy, neutral to slightly alkaline. In heavy clay or in pots add grit or coarse sand. It needs little or no fertilizer.
