in mimicking forest and other natural
environments so plants are better equipped
to withstand stressors.
Davey's holistic PHC approach uses a
combination of diagnostic checkups,
prescription pest management, proper
nutrition and cultural practices to strengthen
plants' natural ability to resist certain insects
and diseases.
Today, Davey continues to pioneer the
tree and plant health industry, developing
best practices in collaboration with leading
academic institutions and environmental
agencies.
We can confidently say that Davey will
be part of the next great tree care
innovation, thanks to our commitment
to comprehensive plant health care
and to John Davey's "do it right or not
at all" motto.
Davey's root
zone fertiliza-
tion method
continued into
the early 1970s.
A Davey
arborist uses a
pneumatic tool
to drill holes into
the root zone,
filling them with
Davey Tree food
for more direct
fertilization.
In 1976, Davey
received a
patent for its
revolutionary
tree fertilizer,
Arbor Green®,
which proved
more efficient
at stimulating
growth than
standard
powders.
Davey Tree
surgeons apply
Davey Tree food
directly to roots
by mixing it into
the soil of the
drip zone on
the U.S. Capitol
grounds in the
early 1900s.
