T
hat was founder John Davey's motto,
passed along from his father to him,
and from him to his sons.
One son, Paul, embraced the motto quite
literally, developing an industry-leading
fertilization method in the 1920s that also
earned him several mechanical patents.
Paul's pioneering fertilization methodology
involved using pneumatic tools to drill holes
into the soil of a tree's root zone so that
arborists (then called tree surgeons) could
pack them with powdered fertilizer. The
carefully drilled holes not only allowed for
better nutrient reach, they also improved
oxygenation for healthier, more vibrant trees.
Paul's passion for do-it-right mechanization
gave Davey arborists long-lasting tools
for tree care. In fact, they were the industry
gold standard until 1976 when, once
again, The Davey Tree Expert Company
developed another groundbreaking method
for tree fertilization.

This time, Davey received a patent for its
revolutionary fertilizer, Arbor Green
®
(and
later Arbor Green PRO
®
). Using an injection
probe inserted into the soil of a tree's root
zone, fertilizer is dispersed through the
probe's tip, bathing the roots in nutrients.
This pioneering technique proved more
efficient to apply and more effective in
mimicking natural growth.
But Davey was not done yet.
In 1987, Davey introduced Plant Health Care
(PHC), a systematic approach to developing
strong, vigorous plants while reducing the
use of pesticides. PHC is literally rooted
