Bonsai can be created from nearly any perennial woody-stemmed tree or shrub species [2] which produces true branches and remains small through pot confinement with crown and root pruning. Some species are popular as bonsai material because they have characteristics, such as small leaves or needles, that make them appropriate for the compact ...
Pruning should take place only during dry weather as wet plants should not be pruned or handled. If possible, plan pruning so new growth will occur during drier parts of the year, late June to early August. [11] Additionally, juniper nurseries should prune trees every 7–10 days in dry weather. [11]
The reduction of chlorophyll production in leaves due to decreased sunlight in the autumn explains why some leaves turn yellow. However, the yellow color can attract aphids, so some trees turn the leaves red instead by injecting a bright pigment. [8] The loss of chlorophyll may also contribute to the abscission process.

The leaves themselves are simple and ovate to oblong-ovate with serrated or crenate margins, to which the tree owes its specific epithet serrata. The leaves are acuminate or apiculate, rounded or subcordate at the base, and contain 8–14 pairs of veins. The leaves are rough on top and glabrous or nearly glabrous on the underside. They are ...
In these species, dead branches generally rot and fall off the tree. A small indentation is left where the branch used to be, and new wood grows around it forming a small hollow. Bonsai gardeners replicate this hollow as a uro by making a small, irregularly-shaped wound in the trunk . For example, when removing a branch from a deciduous or ...
Some people have been known to top trees in order to stimulate new growth. When a tree is topped, many adventitious shoots, known as suckers begin to grow from the wound. This is the tree's response to the sudden loss of leaves. Although the tree is able to produce an abundance of suckers, they are susceptible to numerous problems.

[3] Arborists, orchardists, and gardeners use various garden tools and tree cutting tools designed for the purpose, such as secateurs, loppers, handsaws, or ...
