Garden Soil

Soil Type

Water: Originating from the Balkan Peninsula, rue thrives in well-drained soil and is drought-tolerant, needing weekly watering. As an evergreen, it conserves moisture by retaining leaves. Commonly grown outdoors, rue benefits from mulching to retain soil moisture and reduce watering needs.

Fertilize: Fertilizing rue enhances growth and resilience. Use balanced fertilizers biannually in spring and fall, applying a teaspoon per plant. Wear gloves for safety; oils may irritate. Water the soil before and after fertilization to boost effectiveness and ensure optimal vitality.

Pruning: Rue features aromatic, bluish-green foliage and is resilient. Prune in early to late spring, cutting back stems by one-third to promote dense growth. Remove dead wood promptly, and use gloves and sterilized tools to avoid skin irritation from potent oils.

Propagation: Rue propagates effectively in Spring and Summer with cuttings. Success is indicated by new leaf growth. For optimal results, utilize well-drained soil and provide ample sunlight.

Repotting: Repot rue every 2-3 years in spring to support moderate growth. Use a slightly larger pot with good drainage. After repotting, water sparingly and position in a sunny location, taking care to avoid over-watering during its recovery period.
