Re: REVERSE TAPER??
Hi Astroboy,
Reverse taper is the term we use to describe the trunk of a tree that starts narrower at the base of the trunk and get wider higher up. If you notice in this image, that the base of the tree is thin and higher up its thicker, that is reverse taper.
This image was taken from this article by Walter Pall which i find to be a great read. ( i hope i am allowed to use the image )

Re: REVERSE TAPER??
G'day,
Think of most old trees in nature, how they are fatter at the base of the trunk and then get progressively smaller as they reach the top. It's natural to mimic this in our bonsai. Reverse taper is when the trunk gets fatter as it goes up in one or more sections. Sometimes caused by strong or multiple branch growth from that area. Trauma or insect damage could also be the cause. In most cases it's not desirable cause it looks unbalanced and unnatural - or in some cases it can actually be a great feature like in the bonsai pictured above. Another one of those "rules" that were meant to be broken.
I've read of people hitting their trunks with hammers or other tools to cause callusing which swells. Others cut or scar the thin section so it swells when it heals. Growing sacrifice branches on the area that needs thickening may help too.
Hope this helps mate.
