🌱 How to Care for Soft Caress Mahonia to Prevent Rust?

💧 How to Water

Water newly planted specimens regularly during the first year (approximately every 14 days in summer, less frequently in winter) until the roots are established. After this, the plant manages with natural rainfall and only needs supplemental watering during long dry periods—allow the soil to dry out slightly between waterings.

☀️ Lighting

Choose a spot in partial to full shade; the plant also tolerates some morning sun but should be shielded from harsh afternoon sun, which can scorch the delicate leaves.

🪴 Ideal Soil

Plant in moist but well-drained, humus-rich garden soil. Compost can be added to the soil for better drainage and nutrient content—the plant tolerates most pH levels from slightly acidic to alkaline.
