There are studies from Michigan Technological U at Houghton that show a correlation between high densities of Carex pensylvanica and reduced densities of tree seedlings in northern hardwood forests. Here is a link:http://forestry.oxfordjournals.org/cgi/content/abstract/cpp003v1.If this link does not take you to it then google search Pennsylvania sedge and click on the 4th link. The study is from March of this year. It would seem that the question of control pertains only to the forest habitat in question. Bryce Ruddock , South Milwaukee ,WI

It is a native species which is in high demand for restoration work and native landscaping. Buying it from a nursery it will cost twice as much as other sedges and grasses since they cannot keep up with demand.
Curious,

If you have any ideas or thoughts about controlling Penn sedge let me know. I saw some studies with scarification of the soil and herbicide. No chemical name though. Any thoughts?P Thomas M.
