Description
Camellia japonica and most of its cultivars are considered to be winter hardy to USDA Zones 7-9. Even where winter hardy, unusually cold temperatures in winter (below 10 degrees F), particularly when occurring as a sudden temperature change, can damage these plants. Where winter hardy, Camellia japonica should be grown in moist, acidic (5.5 to 6.5 pH), loose, organically rich, well-drained soils in part shade. Consistent and even moisture is important. Avoid wet soils. Plants do best when protected from direct afternoon sun and wind. Best location may be sun-dappled part shade. Best with a root mulch. Near the northern parts of their growing range, plants should be sited in sheltered and protected microclimates such as near the south side of a home or building. Burlap wraps are sometimes helpful. Plants generally dislike changes in temperature, irregular watering or being moved. Fertilize monthly in spring and summer. If desired, remove all but one bud from each cluster to increase the size of the flower. Prune immediately after flowering.
