I have had daylilies in my yard for 5 years and never had a problem with deer, but this year the deer ate all the buds off the plants and chewed some of the plants almost to the ground. What can I do to keep the deer away from my plants?
A fence is the most effective way of keeping out deer. It doesn't have to be a tall fence, although that certainly works. A single strand of electrified polywire baited with peanut butter will also work fairly well. There is even a wireless version although I do not know how well it works.
Alternatively you can get a dog and install a fence that will keep in the dog.
