Camellia japonica (Japanese camellia), better known as the common camellia, is shrub grown in United States Department of Agriculture plant hardiness zones 7 to 9. It generally grows to 6 to 12 feet tall, although it can reach up to 25 feet. Its mature width is typically 6 to 10 feet. Camellia japonica is an evergreen shrub with white, pink or red flowers that grow to a width of 3 to 5 inches. They bloom beginning in the fall and throughout the winter until early spring and need occasional pruning.
Prune the camellia japonica after it is finished blooming in the spring. You can also prune in the early summer.
Remove diseased, dead or damaged stems. Stems that are too long, make the bush look disproportionate and did not bloom well can also be cut back if desired. However, do not conduct a heavy pruning as you may with other bushes.
Prune the chosen stems with lopping shears. Make a clean cut back within an inch of the parent branch (the branch from which it is an offshoot).
