🌱 How to Care for Common boxwood to Prevent Aphids?

💧 How to Water

Water every 7–10 days during summer, reducing to once a week in winter. Avoid waterlogging — boxwood tolerates brief dry spells but cannot tolerate standing water at the roots. For container-grown plants, always check soil moisture before watering.

☀️ Lighting

Boxwood tolerates full sun, partial shade, and full shade. In regions with very hot summers, a partially shaded position protects the foliage and maintains the deep green colour. In very bright spots, ensure consistent moisture to prevent leaf scorch.

🪴 Ideal Soil

Prefers well-draining, loose soil with adequate calcium content. In heavy clay soils, incorporate perlite or coarse sand to improve drainage. Ideal pH ranges from 5.5 to 8.0. For container planting, use a universal potting mix combined with perlite and grit.
