Soil Type

Water: Black mondo grass prefers moist, well-drained soils and thrives in humid, subtropical environments. While moderately drought-tolerant once established, it requires weekly watering to maintain its lush appearance. Ideal for outdoor landscapes, black mondo grass benefits from natural rainwater, showcasing resilience in diverse climates.

Fertilize: Black mondo grass thrives with balanced nutrition fertilizers during its growing season, especially high-phosphorus varieties that promote flowering. Apply diluted solutions quarterly and water post-fertilization to avoid root burn. Fertilize sparingly in winter, and ensure safe handling and storage of fertilizers from pets and children.

Pruning: Black mondo grass has striking black foliage, ideal for ground cover or ornamental use. Prune black mondo grass in early spring to late winter to remove dead leaves and promote healthy growth, making clean cuts at the base. Regular pruning controls spread and enhances the plant’s bold aesthetic.

Propagation: Black mondo grass features striking foliage in deep purple to black. For successful propagation, divide the underground rhizomes with a sterile tool, ensuring each section has one growth point. Transplant into well-draining, moisture-retentive soil to mimic natural conditions for optimal growth.

Repotting: Repot black mondo grass in early spring every 2-3 years to support its slow growth. Use a pot slightly larger, with well-draining soil. After repotting, maintain consistent moisture without waterlogging to aid recovery and preserve its attractive dark foliage.
