Soil type: Requires fertile, well-draining soil—loamy, sandy, or silty. Avoid chalky or compacted soils.

Watering frequency: Moderate watering; consistent moisture is beneficial, particularly in the first 3–5 years.

Light exposure: Full sun is essential to maintain strong variegation; partial shade may diminish contrast.

Temperature requirements: Hardy to -20°C (−4°F) and heat-tolerant up to 35°C (95°F). Prefers mild, temperate climates.

Fertilization: Apply balanced organic fertilizer in spring; mulch annually to support root health. Avoid high-nitrogen feeds which may reduce variegation.

Pruning: Prune in late winter to remove weak, crowded, or non-variegated shoots. Maintain an open structure to encourage light penetration.

Common pests: Monitor for gall wasps and fungal blight. Regularly inspect foliage, especially due to its lighter pigmentation.

Other care practices: Nut production may be secondary to ornamental value. Plant in a wind-protected site to avoid leaf scorch.
