Stages of Decay 
When decay has reached advanced stages in 
a tree, the heart wood is endangered. The func- 
tion of the heart wood is the structural support of 
the tree. When it is weakened and decay allowed 
to continue, the tree may very likely crash to the 
earth in a strong wind. 
To end this unhealthy condition, the decayed 
wood must first be removed, the decaying action 
stopped, and other material placed in the cavity

Small, dead or broken branches are the ‘Achilles 
Heels” of trees. The trees are powerless to heal over 
the broken ends without help. The result is that decay 
starts at the broken end and continues down through 
the heart of the tree. 
By cutting the broken branch up flush with its point 
of origin, and treating the cut with bacteria resistant 
dressing, the parent branch is able to heal the 
wound and remain sound.
