1. When pruning, the branches should be cut obliquely, and the incision should be flush with the base of the branches, and no residual piles can be left. Scissors should be sharp to smooth the wound and facilitate healing. In order to make trees shorter, pay attention to the direction and position of buds when pruning.

2. The lateral buds branch upward, and the lateral buds branch outward, and the branches can be cut off as designed. The first bud left on the branch bud should be on the other side of the blade, and the top of the inclined plane should be about 3 mm higher than the bud base to prevent it from being too high or too low. Balance should be maintained between the main branches, so that the stems, branches and leaves of camellia can be developed reasonably.

3. Cut the branches obliquely, and the incision should be flush with the base of the branches, leaving no residual piles. Scissors should be sharp to smooth the wound and facilitate healing. In order to make trees shorter, pay attention to the direction and position of buds when pruning. Because the inner buds of camellia are upward and the outer buds are outward, branches can be cut off and buds can be left as designed. The first bud left on the branch bud should be on the other side of the blade, and the top of the inclined plane should be about 3 mm higher than the bud base to prevent it from being too high or too low. Balance should be maintained between the main branches, so that the stems, branches and leaves of camellia can be developed reasonably.

4. When shaping and pruning, we should pay attention to selecting lateral buds with outward branches and moving scissors at the top. This will make the whole branch more and more compact. If you trim the lateral buds that grow upward or downward from above, you will control the crown shape or droop of the tree.

Second, matters needing attention:

Camellia planted on the ground mainly prunes dead branches, weak branches, cross branches and over-dense branches, which obviously affects the branches of trees and sparse redundant buds. Besides the above work, potted camellia should be pruned according to personal preference, but it is not suitable for re-pruning because of its weak growth potential.

Extended data:

1. Camellia is an evergreen shrub or small tree. I like semi-shade, avoiding the hot sun. Like warm climate, the suitable growth temperature is 18 ~ 25℃, and the initial flowering period is 2℃. Slightly cold-tolerant, general varieties can tolerate-10℃ low temperature and heat, but the growth above 36℃ is inhibited. Like high air humidity, avoid drying, and grow in areas with annual precipitation 1200mm or more. I like fertile and loose slightly acidic soil, and the PH value is preferably 5.5 ~ 6.5. There are two buds a year, the first is spring bud, starting from March to April; Summer buds sprout from July to September. The flowering period is long, most varieties are 1 ~ 2 months, and the single flower flowering period is usually 7 ~ 15 days. The flowering period is from February to March.

2. There are about 220 species of Camellia in Theaceae, among which Camellia japonica, Camellia yunnanensis, Camellia japonica and Camellia japonica are all important ornamental flowers and trees.

Camellia is an evergreen flower, which blooms in winter and spring, with graceful flowers and bright colors. Comrade Guo Moruo praised: "Camellia blossoms as early as peach trees, and a hundred clouds are proud." Yunnan tea people once wrote a poem praising: "Strictly speaking, camellia is a provincial flower, but now everyone says peony is good, and I say peony is not as good as tea." "
