After the planting of Magnolia, a strong pruning should be carried out. Usually, 5 to 6 main branches per plant and 7 to 8 short buds per branch are enough. Before overwintering, we also need to prune the dense branches and redundant branches. In winter, magnolia is in hibernation. At this time, pruning can reduce the damage to magnolia trees.
