🌱 How to Care for Garlic Mustard to Prevent Slugs and Snails?
💧 How to Water
Keep the soil evenly moist, but strictly avoid waterlogging. During hot summer weeks, daily watering may be necessary. In the garden, natural rainfall is usually sufficient, except during prolonged dry periods.
☀️ Lighting
Semi-shaded to shaded locations are ideal—garlic mustard thrives best under light tree canopies or on north-facing slopes. It does not tolerate direct midday sun well and should be avoided.
🪴 Ideal Soil
Nutrient-rich, humus-rich, and slightly loamy soil with good moisture retention is optimal. The plant tolerates pH values from 6.0 to 8.0. Container cultivation works well with standard potting soil, as specialized herb soils are often too dry.
