This is a very nice specimen for a rock garden or for container planting because it is a very slow grower it can be put in small areas. It best placed out of where it can be hit by harsh winter winds. This is also a great plant for bonsi trees.

Buxus can suffer from boxwood leaf miner, nematodes and mites. Recently Boxwood blight has become a major problem both in Europe and most of North America. The fungus Cylindrocladium buxicola causes leaf spots, defoliation and even extensive die-back. The disease can be spread by water splash, tools and footwear and can survive for up to six years in the soil. It thrives in moist, humid environments but is killed when exposed to temperatures in excess of 33 °C for at least a week. The disease also affects Pachysandra, Sarocococca and Buxus balearica, sinica, macowanii, microphylla, bodinieri, glomerata, harlandii, sempervirens and riparia.

Propagate in mid-summer by taking semi-ripe cuttings from the current season's growth. Collect in the early morning using a sharp knife to cut pieces 10 - 15 cm in length. Remove all leaves from the lower third and pinch out any soft terminal growth. Dip into a number 2 rooting hormone, insert into trays or pots of cutting compost (50/50 mix of compost and sharp sand or perlite) and water well. Place in a propagator with bottom heat set at 15°C with or without mist; rooting should occur in 4 - 6 weeks.
