Water: Highclere holly thrives in consistently moist soil, requiring weekly watering to maintain health. As an evergreen, it retains foliage year-round, necessitating stable hydration. Indoor cultivation helps manage its water needs effectively, ensuring it receives the moisture essential for continued growth.

Fertilize: Highclere holly needs minimal fertilizer, ideally applied once in early spring and autumn. Use a nitrogen-rich compound for vibrant leaves. Avoid fertilizing when temperatures exceed 30°C (86°F) to prevent root damage. Over-fertilization can lead to large, dull leaves, indicating a need to stop.

Pruning: Highclere holly thrives with light pruning in early to late winter to control size and promote health. Remove dead or crossing branches, making clean cuts to prevent disease. Regular pruning encourages vigorous growth and maintains its tidy, aesthetic appearance.

Propagation: Highclere holly is an evergreen shrub that can be propagated via cuttings from healthy semi-hardwood stems. Use sharp, sanitized tools for slanted cuts, apply rooting hormone, and place cuttings in well-draining medium within a humid environment to promote stable root growth.
