Boxwoods do best in dappled shade where they get full sun for a portion of the day.
Too much full sun, especially in hot climates, will damage their leaves.
Used as foundation plantings around the house, boxwoods would be happiest on the north side, and forced to suffer the most direct sun on the south side
Thrives in part shade in evenly moist, well-drained soils.
While full shade is tolerated, the plant will not be as vigorous and its foliage not as dense. Full sun exposure may scorch the foliage.
Boxwood can grow in a variety of soils as long as there is not too much sand or too much clay.
