Pruning and shaping of plum blossoms: Pruning and shaping of plum blossoms is a technical job. Pruning should start with seedlings. When the seedlings grow to 20-25 cm long, the top should be cut off. After germination, 3-5 branches should be kept as main branches. When the main branch grows to 10- 15 cm, the core should be removed to promote the robust branches and the formation of flower buds. Prune after flowering. When the flowers wither, leave 2 ~ 3 buds from the base. When the new branches grow to 5 ~ 6 leaves, pick the heart and leave only 3 ~ 4 leaves to promote the growth of more flower branches. Prune repeatedly every year to enrich branches and increase buds.
