Most camellias have a steady growth habit and will most probably have established a well constructed root system that will assist the plantS to continue to grow even in harsh drought conditions in approximately three years of being planted into the ground. This is not so for camellias that are growing in containers, as they have had the radical cut off when only a small plant, this enables the plant to form a series of ‘feeder roots’ to supply the needs of the plant. Pot grown plants need more care than those growing in the ground.
Irrespective of flower size, most camellias can grow to become large trees, that is if you want a camellia to grow up to 30 feet. The camellias that bear miniature blooms can grow to that size also, so if you want your camellias to be maintained at a certain height, you must prune them.
Camellias have differing growth habits, some are a tall conical shape, while others grow more densely. There are a few that are grown for their habit of growing low to the ground.
