Like most of those who responded to this post I have a serious deer problem. I have not yet tried human hair (dog hair has no effect), however I have used both Deer Out and Liquid Fence sprays, repellents that are staked in the plants, repellents that are citrus based in net bags, Milorganite, etc. Everything works for a short time. Part of the problem is that the deer adjust quickly and are random browsers. The rest of the problem is rain, of which we've had daily showers lately, making it impossible to protect the plants with sprays. This year all my daylilies were stunning, the first time in many seasons. The night before last a deer decimated most of them, nipping buds and parts of flowers. Yesterday morning I chased one out of a flower bed at 6:00 am; she didn't go far! Fencing is not an option, nor is an electric fence (multiple beds and locations). I would love to find something which is a more permanent solution. I also have a neighbor who feeds the deer apples and corn which doesn't help the situation. I don't mind the deer grazing on the "wild" part of our six acres - if they'd just leave my *&%$ hostas and daylilies alone! Oh, and I've also tried planting natural repellents (sage, thorny ground covers) among the edibles - no luck there either. Another neighbor suggested net socks filled with Downy softener beads, however I'm not sure how that might affect the plants. (Thoughts?)
