Pruning and shaping of miniature bromegrass bonsai: Pruning time is generally appropriate in late spring and early autumn, and bromegrass stumps germinate strongest and grow most vigorously in these two seasons. Long branches, overlapping branches, cross branches, radiating branches, dead branches and pest branches should be cut off at any time. But it should be noted that when the weather is hot, it is easy to burn new buds and roll leaves. Therefore, it is best to put it in the shade after pruning until the germination is normal.

From May to June, the branches began to sprout on the dry branches. According to the pre-conceived or designed sketch, unnecessary sprouting branches can be wiped off and the branches in the ideal position can be kept. When 10 ~ 15 leaves are extracted from each branch, the heading can be started. In order to make the branches stout and plump, generally, the terminal 1/2 ~ 2/3 should be picked first to promote the axillary bud germination at the lower part of the branches; From August to September, if there is sufficient water and fertilizer supply and sufficient light, you can hit your head almost every 5 to 7 days. At this time, in order to prevent the branches from growing too long and losing their graceful state, the 1/3 at the top can be removed every time three leaves are extracted from the new shoots, so that each branch presents "three bends in one inch" and the branches will be particularly plump and compact. Generally, in July and June of 10, you can hit the head about 15 ~ 20 times, which can form an ideal branch in that year.
