I planted a half acre of oats in mid-April.The oats came up pretty well although there's some weeds snaking through them now that they've turned. At no point, so far, have I seen deer eating them. I've seen them walking through them, I see trails in them and I've even see where they bedded in them in one area. However, they haven't been eating them as far as I can tell. I expected them to start once the seeds hardened, but no dice so far. What do the experts say?
