Late to the party on this post, but Ernst is a great place. I'm eastern Ohio and have done a lot with them. I agree with the first year you feel like a failure. I did CIR from Ernst last year, and doesn't look like I did anything. They told me 3 years to get height on it, so we'll see how it goes this year. Do you all spray anything special strictly for the switchgrass or mow it at different intervals to keep other weeds back? or just let it go?
