Pinching

Identify the terminal bud: The terminal bud is the growing tip of a branch. It is typically located at the end of the branch and is usually larger than other buds.
Pinch the terminal bud: Use your thumb and forefinger to pinch off the terminal bud, leaving a small stub behind. This encourages the growth of lateral buds, which will create new branches.
Repeat the process: Pinch the terminal buds of all branches that need to be encouraged to branch out.

Cutting

Select the branch to be removed: Identify the branch that needs to be removed. This may be a branch that is growing in the wrong direction, is too long, or is simply not needed.
Make the cut: Use pruning shears or a saw to make a clean cut just above a bud or a node. A node is a point on the branch where leaves or branches grow.
Smooth the cut: If you used a saw, use a file to smooth the cut and prevent the branch from drying out.

Wiring

Choose the right wire: The type and thickness of wire used will depend on the size and strength of the branch. Thinner wire is typically used for smaller branches, while thicker wire is used for larger branches.
Wrap the wire around the branch: Wrap the wire around the branch in a spiral pattern, starting at the base of the branch and working your way up. Leave some space between each coil of wire to allow the branch to grow.
Bend the branch: Once the wire is in place, carefully bend the branch into the desired position. Be careful not to break the branch.
Remove the wire: Once the branch has grown into the desired position, remove the wire. The branch will hold its new shape.

Defoliation

Choose the right time: Defoliation is typically done during the summer months, when the tree is actively growing.
Remove the leaves: Carefully remove all or most of the leaves from the tree. Use your fingers or pruning shears to remove the leaves.
Provide adequate care: After defoliation, ensure the tree receives adequate water and fertilizer to support new growth.

Shaping a Bonsai Tree

Shaping a bonsai tree is a gradual process that requires patience and skill. The goal is to create a tree that is visually appealing and represents a particular style.
