Thickening Branches and Roots complete.
To get a strong branch, we have to let the branch
grow long and freely. At the same time we can remove
all the leaves except those in the tip. By doing so, the
branch will grow thicker and at the same time the
sub-branches will grow. The most important thing
is to get thick branches that are proportional to the
thickness of the trunk. We can cut off and shorten
the branch when the thickness required is achieved.
Once the main branches structure is achieved, we
can continue the process to build the sub-branches.
