RE: fescue and cool season grasses

Larry - I would go for it, but very, very soon. In fact Friday probably would have been prefect. If you have Elymus in your planting there is a good chance that it will get stunted, but probably not killed. We use this kind of early herbicide treatment to help manage some of our nursery beds here in southern Wisconsin - and in fact were spraying Roundup the end of last week. Your little blue and side oats should be safe.

Subject: fescue and cool season grasses

My wife and I planted 18 acres in the fall of 1998 (southeastern WI). In the second growing season we counted 37 species of forbs and 5 grasses (about 100 originally planted).  There are some patches of cool season grasses, none greater than 1/8 acre, and some small patches of reed canary grass.  If I were to spray these patcheswith Roundup in the next couple of weeks (april 7-21) would there be much loss of natives.  The last snow just melted and the only green I can see is grass.  I assume the little bluestem and side oats etc., won't be emerging till much later but are there any forbs at risk?
