picture is worth a thousand words. Here is an American elm that was planted too
deep, leading to its failure during a wind storm in Edmonton in July 2009 . This
tree showed no obvious signs of stress before it failed, increasing its
hazard potential. The leaves are wilted because the tree was lying in the sun
for a few days before the forestry unit was notified. </FONT></SPAN></DIV>

agree with the majority of writers. Planting too deeply here on the west coast

In my view Gilman is correct. In the last several years we have been
removing lots of excess soil from the root ball and haven’t seen any issues
with root crown injury. </SPAN></P>

Hannah Mathers stated at the SNLA conference that the root shank (area of
exposed root tissue that results from production practices) should never be
exposed above the soil line because it may be the cause of increased crown
injury. She explained that it may not be cold hardy, may be prone to sunscald
or easily injured by herbicides. I have not seen any increase of injury to
this exposed root crown area and can not justify changing our planting
practices when I have seen the issues of planting too deep.</SPAN></P>

everyone,<BR><BR><BR><BR>I have recently attended to two seminars, one with
Dr. Ed Gilman and one with Dr. Hanna Mathers. The two have very
different views on planting depth.<BR><BR>I would like to hear others opinions
on planting trees at the same depth as previously planted vs. planting higher
(at or near the root flare). It seems there may be possible problems
associated with either practice when planting container or bareroot trees and
some issues may be species specific. We have had good results with
planting depth near the root flare and have not experienced any issues because
of it. I am interested in your comments.<BR><BR><BR><BR>Lorilee
