I have just purchased a property that has really over grown grass. The land is elevated and I don't think it is draining properly, but too early to tell. The problem is there is a large amount of this 2 ft high "swampgrass" and "horsetails" and I was wondering what is the best way to get rid of it? I was thinking of roto-tilling the area and placing new sod and seeding or turf. There is a small creek that runs through the middle of the yard that may be the cause of this swampgrass. I have begun to weed wack the area and want to apply something that will work on swampgrass and horsetail. Pls help.
