Ilex crenata, commonly known as Japanese Holly, is a popular evergreen shrub frequently shaped into topiary balls. Renowned for its dense, small, dark green leaves that resemble those of boxwood (Buxus), it serves as an excellent alternative in areas where boxwood may be prone to blight or pests. Japanese Holly is ideal for formal garden settings, patios, and pathways, adding structure and elegance.

Key Characteristics of Ilex Crenata:

• Foliage: Small, glossy, rounded leaves that closely resemble boxwood, remaining green year-round.
• Growth Habit: Dense and compact, it can be pruned into neat shapes like balls, cones, or spirals. Ilex crenata grows at a moderate rate, making it easier to maintain topiary forms.
• Size: Ilex crenata topiary balls can be kept in various sizes depending on pruning, typically ranging from 30 cm to 1 meter in diameter.
• Flowers and Berries: Small white flowers appear in late spring, followed by small black berries on female plants, which add seasonal interest.

Growing Conditions:

• Soil: Prefers well-draining, acidic to neutral soil, and can tolerate slightly alkaline soil as long as it’s not excessively chalky.
• Light: Thrives in full sun to partial shade; it’s more shade-tolerant than many other holly varieties.
• Watering: Regular watering is important, especially during dry periods, but avoid waterlogging. Ilex crenata is fairly drought-tolerant once established.
• Pruning: Prune lightly once or twice a year, preferably in late spring or early autumn, to maintain a rounded topiary shape. Use sharp shears to achieve clean cuts.
• Feeding: Feed with a balanced, slow-release fertilizer in spring to encourage lush growth.
• Mulching: Mulch around the base to retain moisture and control weeds, but keep mulch from directly touching the trunk to prevent rot.
