<P class=MsoNormal>FYI - This might be of interest to other urban
foresters.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We have a lot of open “tree wells”, they are usually 4 or 6
feet square tree pits in hardscape without a tree grate, and weeds have been an
on-going issue. Especially now that we don’t spray pesticides much
anymore. <o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We’ve been looking for some alternative solutions for a few
years now. One product that we have tried that seems to work pretty well
are the recycled rubber tree rings but of course the problem is that they are
round and don’t come in the right sizes. Recently we were able to find a
manufacturer who is going to custom make some large rubber tree mats for
us. These are 100% recycled rubber, LEED certified, they come in a variety
of colours and I believe they are porous so they allow water and air to
pass.<BR><BR><o:p></o:p></P>
<P class=MsoNormal>We’re going to try some out. In case others are
interested in trying this, here’s what we’ve been quoted by Eco-Flex out of
Alberta (<SPAN
