One of many memories from my
youth growing up on a farm in cen-

(DED) swept through the area.
Now, several decades later, the
symptoms of DED are again a
common sight in elm trees around our
countryside. Classic symptoms
visible this time of year are flagging
or wilting of leaves on whole
branches. Once these symptoms
appear at a noticeable level, the
whole tree usually dies within a year
or so afterwards.
Many folks thought elms were
making a comeback as young elm
trees have become very common
across our landscape, many of them
reaching a significant size.
Unfortunately, in the last five years
or so, DED has once again become
much more common as well. This
comeback of both young elm and
now the disease is not really
surprising once you understand a few
details relating to the disease and how
it is spread.
Dutch Elm Disease was first
introduced into the U.S. in the 1930s
(and Quebec in 1940) on logs
imported from Europe. The disease
is actually a fungus that grows in the
circulatory tissues of elm trees and
causes blockage of the tree's water -
conducting system. As an introduced
organism, our native trees had little
