Japanese stiltgrass invading my woods

Asked July 18, 2017, 7:02 AM EDT

I am resigned to just pulling out the Japanese grass, but what can I plant in its place? it is in the woods of my property approx. 1 acre. I am trying to replace my lawn with meadow and forest, but so far I have a lot of Japanese stiltgrass. I'm trying to encourage other things to grow. Thank you

We feel your pain but are encouraged by what you are trying to do.
Stiltgrass is an invasive pest, and unchallenged has outcompeted many of our native plants.
Given the large area you are trying to control, we'd suggest a careful application of an herbicide with the active ingredient glyphosate to knock it down.
It is an annual weed. Whether you hand pull or spray, try not to let it go to seed or you will have more seeds that will be in the soil waiting for their chance next year.
Here is a page with more information on Stiltgrass: https://www.nps.gov/plants/alien/fact/mivi1.htm
With time, and effort, you should be able to win.
The plants we'd suggest as replacements would be natives to our area and suited to your particular site conditions.
Take a look here for our Native Plants page:http://extension.umd.edu/hgic/native-plants
which includes links to great publications and plant selection guides.
