Liquid Fence is also my liquid of choice. It smells awful but for that reason it works great. I have a gazillion varities of hosta that they ate like lettuce before I started using it.
We moved to an old farmhouse and I’d never had to deal with deer before. I couldn’t figure out what was happening to my roses. My pastor, who is a rosarian (breeds his own) clued me in. I have to spray weekly because it’s different herds moving through all the time but I haven’t lost anymore new growth or rosebuds. I love the stuff.
