🌱 How to Care for Wallflower to Prevent Aphids?

💧 How to Water

Water deeply approximately once a week during dry weather, letting the top few centimetres of soil dry out before watering again. Wallflowers are drought-tolerant and strongly dislike waterlogged conditions; overly wet soil quickly leads to root rot. Always water at the base—wetting the foliage or flowers encourages fungal disease. In winter, reduce watering significantly, especially on heavy soils.

☀️ Lighting

Wallflowers require a minimum of six hours of direct sunlight per day. Plant in full sun for the most prolific flowering and strongest fragrance. In very hot climates, light afternoon shade may prevent heat stress, but in temperate zones avoid shaded positions entirely—low light results in leggy growth and poor blooming.

🪴 Ideal Soil

Use free-draining, moderately fertile soil with a pH between 6.0 and 7.5. Wallflowers thrive in gritty, sandy, or chalky soils and naturalize readily on old walls and stony banks. Avoid heavy clay or moisture-retentive composts. Improve drainage by incorporating coarse grit or perlite. Lime the soil if it is acidic, as wallflowers prefer neutral to slightly alkaline conditions.
