First cut off all the tillers, then keep 3 ~ 5 main branches on the trunk, cut off all the side branches, cut the long main branches short, keep 2 ~ 3 strong side branches in the next year, and then trim the usual branches and leaves.

1, suitable height

Generally, when the Fraxinus mandshurica tree grows to a certain height, it needs to be trimmed and fixed, and the height of the fixed rod is 2.8 ~ 4 meters. At this time, the ash tree is full of vitality, and the fixed pole can make it grow well, thus becoming the trees modeling we want.
