The best time to prune camellias is spring. For optimal results, use a sharp tool like pruning shears, hand cutters, or a knife to trim your plants' flowers and branches.
Focus on removing weak, overgrown, or dead branches, cutting them as close to the base as possible. It's also vital to eliminate any diseased or pest-infested sections promptly.
Diseased branches should be removed immediately, regardless of the season, while comprehensive pruning should take place once every few years to avoid stunting plant growth.
