🌱 How to Care for Japanese Boxwood to Prevent Spider Mites?

💧 How to Water

Water Japanese Boxwood every 7–14 days, allowing the top inch of soil to dry slightly between waterings. Avoid waterlogging, as consistently wet roots promote root rot. During hot summer months, you may need to water more frequently. Always water at the base to keep foliage dry.

☀️ Lighting

Japanese Boxwood thrives in full sun to partial shade (4–8 hours of direct light per day). In hot climates, provide afternoon shade to prevent leaf scorch. Indoors, place near a bright, south- or east-facing window. Avoid dense shade, which causes leggy growth and reduces foliage density.

🪴 Ideal Soil

Use well-draining, slightly acidic soil (pH 6.0–6.5) enriched with organic matter. A mix of loamy garden soil, coarse sand, and compost works well. Avoid heavy clay soils that retain excessive moisture. Mulching around the base helps regulate moisture and soil temperature.
