We recently planted a dryland lawn with the intent to use it as pasture a few hours a day. After planting it, I realized it had Fawn Tall Fescue seed in it. I know there can be issues with allowing bred mares to consume it due to a toxic fungus. My question is, what are people's experiences with it? Recommendations? I have talked to 2 vets who were not very reassuring, but not terribly discouraging either. Just looking for some input. Thank you!
