For years I suffered the loss of tulips, hosta and euonymous to deer.
Last year I followed a friends advise and put bamboo stakes in the
garden near thier favourite snacks, tied pieces of rags to them and
every other night I sprayed the rags with Downy fabric softener.
I also tied a few rags here and there along the perimeter of our
property and did the same thing. I had tulips and hostas galore this
year. Good Luck
