Plant Profile: Buxus microphylla var. japonica

The Japanese boxwood is an evergreen shrub characterized by its fine texture and rounded shape, typically reaching a height of 6.5 feet. In landscaping, it serves effectively as a low hedge, foundation plant, edging, or as part of a shrub border. This plant responds well to pruning and shearing; however, it’s important to avoid trimming before the last frost of spring to prevent damage to new growth. Propagation can be achieved through stem cuttings, or it may self-seed under ideal growing conditions.

This boxwood thrives in moist, cool soils, so it’s advisable to apply a heavy layer of mulch around its roots. It prefers well-drained soil with a pH ranging from slightly acidic to slightly alkaline and benefits from dappled to partial shade. While it can survive in full shade, it may become leggy and sparse in foliage. Exposure to full sun can lead to a reddish tint in the leaves. As a slow-growing shrub, it is also sensitive to excessive fertilization, and new growth may be susceptible to frost damage. Once established, however, it demonstrates considerable drought resistance.

Additionally, this plant is resilient against drought, deer, rabbits, and nematodes.

**Insects, Diseases, and Other Plant Issues:** Growing this plant can present challenges. Boxwood mites and leaf miners may target stressed specimens, while blight and leaf spot can also pose threats. Root rot is a risk in poorly drained soils, and foliage can suffer from scorching in intense summer heat or harsh winter winds.
