[MAIPC] FW: Stilt grass question

Milo,
I also am learning to "manage it". I am surrounded on 3 sides (one
uphill, one downhill) of stiltgrass. Not too worried about downhill;
but water dispersal from the top (roadway) and side (neighbor who graded
his property to drain into mine (to be explored legally) caused me to
think about how to protect the meadow we are establishing.
Along the top I built a 200 ft swale that takes the storm water from the
road and dumps it onto an area of my property that will be "forever
lawn". This gets mowed.
Along the line with my neighbor, I installed 300 ft of silt sock AND
silt fence. This dramatically reduced the damage done by his water
drainage and stops the stiltgrass seed at the property line. He knows
better than to complain about the view (which on my side is blocked by
winterberry, Father Gila, pawpaw, etc).
To get rid of stiltgrass in areas I am protecting, I mulch (pine fine),
pull, torch and use a pre emergent in areas with perennials and an
herbicde that targets it in areas that have grasses. I even planted
native grasses that are tolerant of that herbicide.
The area below is 7 acres of solid stiltgrass; seems to even be killing
the multiflora rose. Called the owner to see if I could work with him
but....
Interestingly, my area has NOT had a deer problem (been here 30 years)
and since I have cameras I know deer are not here at night. The seed
here is dispersed by water flow. There is no browse line. And I know
the problem with the area below came from heavy disturbance about 5
years ago. Before that it was a healthy old field.
