Buxus microphylla japonica, commonly called Japanese Boxwood, is a compact, slow-growing evergreen shrub with small, rounded, glossy green leaves and a naturally dense habit. It clips beautifully into tight shapes, making it a favourite for formal hedges, borders, parterres and topiary.
In Indian gardens it is widely used for low edging along pathways and beds, in containers framing entrances, and as a classic bonsai subject. It tolerates regular shearing and handles a range of conditions, though it prefers a position protected from the harshest afternoon sun in hot regions.

Care guide
| Sunlight |
Full sun to partial shade; in hot Indian plains give afternoon shade to prevent leaf scorch. |
| Watering |
Keep soil evenly moist; water regularly in summer and avoid waterlogging. Reduce in cool, wet weather. |
| Soil / mix |
Well-drained, fertile loam; tolerates slightly alkaline to neutral pH. Add compost and ensure good drainage. |
| Temperature |
Thrives at 15-30°C; tolerates mild frost but struggles in prolonged extreme heat above 38°C. |
| Humidity |
Adaptable; moderate humidity is ideal. Ensure airflow to reduce fungal issues in monsoon. |
| Fertilizer |
Feed a balanced NPK or compost in spring and again in monsoon; avoid heavy feeding in peak summer. |
| Pruning |
Shear lightly 2-3 times a year to maintain shape; best after spring flush and again post-monsoon. |
| Repotting |
For containers/bonsai, repot every 2-3 years in spring, root-pruning lightly into fresh well-drained mix. |
| Propagation |
Semi-hardwood stem cuttings in the cooler months root readily under humidity. |
| Pests & problems |
Watch for boxwood leaf miner, mites, scale and root rot in poorly drained soil; treat early. |
| Toxicity / safety |
Toxic if eaten; leaves and stems contain alkaloids that are harmful to pets and children if ingested. |
| Difficulty |
Easy |

Growing tips
<p>In the hot Indian plains, position boxwood where it gets morning sun and afternoon shade to avoid leaf scorch; in the hills it tolerates full sun.</p><p>During the monsoon, ensure sharp drainage and good airflow to prevent root rot and fungal blight. Mulch the base to keep roots cool and conserve moisture through the dry summer. Time your main pruning just after the spring flush and again after the rains.</p>
