<DIV><FONT size=2>Interesting question. I have never heard of this happening
with Fraxinus. Tree roots usually respond to surrounding conditions - so if soil
is dry roots will "look" for moisture but usually foundation drain pipes only
function if the soil is saturated to begin with unlike a sewer pipe that is
always full of moisture. </FONT></DIV>

<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>
