resinous species does.

Do not use an ordinary garden-tree wound sealant on bonsai as they can be
difficult to remove once hardened, potentially causing further damage to the tree.
A repotting time soil sieves are needed to remove fine particles and dust
from newly mixed bonsai soils. Root hooks are often used for removing old soil
from around bonsai roots and for combing out though I would personally
recommend using a mixture of hands and a chopstick, as these cause less
damage when potting on new material for the first time and for repotting
Drainage Mesh is essential for stopping bonsai soils from dropping out
through drainage holes in bonsai pots.
Additionally, a small knife and a small hand saw (with large teeth, fine-tooth
saws will not cut through live wood effectively) are items that though not
essential, are useful items to add to the toolbox.
Wire

Wire is commonly used in bonsai to allow accurate shaping and positioning
of branches and trunks. It is also needed for anchoring in newly potted trees and
drainage mesh.
Custom made aluminium wire is readily available from bonsai outlets and
occasionally garden centres. It is worth investing in three or four different gauge
wires that should be able to deal with shaping a variety of branch and trunk
thickness. I would recommend purchasing 1mm, 1.5mm and 2mm gauges at
first.
The Japanese traditionally use copper wire for its superior holding power
though it is now becoming less popular and is harder to source commercially.
It should be noted that plastic-coated wire available from garden centres and

a number of other alternatives to bonsai wire are not only unsightly, have little
'holding' power but also contain metals that can cause severe damage (sometimes
with fatal consequences) to trees when they come into contact with the cambium
layer, the 'living tissue' of the tree.
