Do to the overwhelming amount a negative criticism by a few individuals on
this list, I am only willing to get into debate by way of email. I have a
background in tree biology, my negative critics do not. I am willing to
answer any questions you may have. If I do not have the answer I know where
to get it, based on a thorough understanding of tree biology. Contact me at
A good foundation for understanding trees,
associates and treatments, can be found he www.shigoandtrees.com Most
topics, correct planting, mulching, pruning and fertilization can be found
at www.treedictionary.com

Happy gardening!

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
Some people will buy products they do not understand and not buy books that
will give them understanding.
