🌱 How to Care for Scotch Rose to Prevent Spider Mites?

💧 How to Water

Water young seedlings regularly during the first season until they are well-established. Mature plants are very drought-tolerant and only require watering during prolonged heatwaves – too much water in heavy, moist soil is more harmful than too little.

☀️ Lighting

Plant in a location with full sun (minimum 6 hours of direct sunlight per day) – this ensures the most abundant flowering and greatest resistance to fungal diseases. The plant also tolerates lightly shaded spots, but then it blooms more modestly.

🪴 Ideal Soil

Prefers well-draining, sandy or stony soil with a pH from slightly acidic to alkaline (it readily grows on limestone); it also tolerates clay and chalky soils, provided they are well-drained. Avoid waterlogged locations and overly fertile, heavy soils.
