Pruning and shaping of ash bonsai: For trees that are particularly lush, in addition to the usual control, you can also pick the leaves and cut them into pieces. Ash has two growing seasons, spring and autumn. In spring, everything recovers, and the earth is full of flowers, which is also the time when the buds of ash trees sprout the most. At this time, the new buds that grow in unnecessary parts should be erased in time. After a short dormancy period in midsummer, the second growth peak will appear in the middle and late August every year. Although there are not as many new buds as in spring, they should be erased in time.

After the first frost in autumn, when the trees wither due to frost, the branches are bare, which is very conducive to observing the direction of branches (slices), interspersed back and forth, strewn at random, location and shape. At this time, you can carefully trim the branches and tie them. It can be cut in place with scissors, and after it is cut in place, it can be drawn in place with aluminum wire winding and bending; Some branches are too high or the direction is not good, so use aluminum wire or rope to pull them in place. Pay special attention to its opposite branches and frog leg branches: the fixed branches on the trunk should be staggered with the first and second branches, and the opposite branches should be cut off; Frog leg branches can be cut short, or they can be changed into crutches while growing.
