Subject: Stilt grass question

 

Hi Marc, 

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.

 

thanks

Jan Steiner
