Woodust,
That Fescue may hard on cattle but it will kill horses. But they have developed a strain now that is fungus free. But my son still won' t gamble on using it in our hayfield. But for that reason, I would rather use annual Ryegrass as a companion crop for Clover. After a couple good frosts, it' s mostly gone and the Clover takes over. A good clipping and it adds humus to the soil.
