You may also be getting the "mulch effect". NYS DEC has done work
at Minnewaska SP that suggests mulching stiltgrass along trails
suppresses it.<br>

<p class="MsoNormal">I agree with Bud, and I was going to
say Hollies and laurels/rhododendrons/azaleas generally
prefer to grow in acidic soils. You should also notice
less stilt grass growing in pine forests and under large
pines due to acidity of decomposing pine needles.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'd further venture to say the rate of
decomposition of the strong holly and laurel leaves may be
playing a role. The dense lignin/cellulose content of
holly leaves means it takes at least two years for the
leaves to break down. My thought is that these trees may
be self mulching and stilt grass may have a hard time
establishing in areas of dense, long lasting leaf litter.<o:p></o:p></p>

Subject: Stilt grass question<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Hi Marc, <o:p></o:p></p>
<p>Tom (Crone) and I were walking around
the back end of Greenbelt Park today.
He was checking on some multiflora
rose he'd cut earlier as well stilt
grass he cut. But I noticed something
I hadn't before. There were large
swathes of stilt grass that had bare
patches within those areas. The common
denominator was Holly tree leaf shed.
We started searching elsewhere and
found the same correlation. The stilt
grass totally avoided wherever the
dropped holly leaves landed. Have you
seen this before, or know if there's a
specific chemical in the leaf that
inhibits or kills the grass? Or some
other symbiotic relationship creating
the inhibition? I'm really curious to
know. As we were driving out of the
park, I started looking at the
mountain laurel and what I saw didn't
seem to be surrounded by stilt grass
either.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>thanks<o:p></o:p></p>
