When planting Ilex crenata, it's crucial to ensure the soil is well-drained and slightly acidic, as this plant thrives in such conditions. After removing the plant from its pot, immerse it in water to thoroughly hydrate the roots. Dig a hole deep enough to accommodate the root ball, positioning it so that the top sits level with the surrounding soil. Backfill the hole with soil, firming it down gently to remove air pockets. Apply a thick mulch layer of bark, compost, or manure around the base to help retain moisture and suppress weeds. Keep the plants well-watered during the first few months after planting and during prolonged dry periods.
Keep the soil consistently moist, particularly during the establishment phase and in dry weather. Ilex crenata does not tolerate drought well, so regular watering is essential to maintain its health. Water deeply to ensure the moisture reaches the roots rather than just wetting the surface.
Prune Ilex crenata to maintain its shape and encourage dense growth. Throughout the year, remove any weak, dead, or damaged branches using sharp secateurs or loppers. For topiary shapes, such as spheres or cones, trim regularly to preserve the desired form. Pruning also helps improve air circulation, reducing the risk of disease.
Feed Ilex crenata in spring with a balanced, slow-release fertilizer to promote healthy growth. This provides essential nutrients that support vibrant foliage and strong root development.
Ilex crenata is hardy and can withstand cold weather, but it's advisable to protect young plants from harsh winter winds, which can cause leaf scorch. A windbreak or fleece can help shield the plant during extreme conditions.

The larvae of this pest feed on the roots of Ilex crenata, leading to wilting and poor growth. Adults can also notch leaves, causing cosmetic damage. Control measures include using nematodes or insecticides specifically designed for weevils.
This fungal disease causes small, brown spots on the leaves, leading to premature leaf drop. Ensure proper air circulation and avoid overhead watering to reduce the risk of leaf spot. Fungicidal sprays can be applied as a preventative measure.
