Howdy all!

A few weeks ago I noticed something nibbled the top 1/3 off of one of my rose
buds. The next day something nibbled on ANOTHER bud. Well, yesterday I noticed
that something ate ALL the buds off of 2 of the 4 bushes. What in the world
would want to eat thorny rose buds and what I can I do about it??
(Aside from a fence, I mean )

TIA!
MICK!
