There are a lot of deer in my neighborhood as there are very heavily wooded hills behind my house, I have had the deer eat my tulips (I stopped plantong them) and I don't have any Hosta because deer love to eat them.
I try to plant flowers that deer don't like including daffodil, marigold and hyacinth, I have found that Milorganite, which is a fertilizer, is quite effective at repelling them.
