style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Does anyone have experience with
<SPAN class=SpellE>Fraxinus</SPAN> ever having entered and plugged perforated
drainage pipe? I assume the deeper the pipe the less chance of it happening. I
am only familiar with Salix, and sometimes <SPAN class=SpellE>Thuja</SPAN>
<SPAN class=SpellE>plicata</SPAN>, doing this. My feeling is that a tree’s
roots would not search out drain tiles unless it was suffering drought
conditions. The water held in the soil is a much more constant supply with
adequate rain.<o:p></o:p></SPAN></FONT></P>
