I don't think they like it too well, but like someone once said... they don't know until they try it. And enough were trying it on mine that I fenced mine in.

I used some deer-away spray on bush beans and things like that, and it really works. But I didn't want that rotten egg smell on my asparagus. (I now have everything fenced)

I have some relation who have a patch and the deer don't bother it at all.

But again, I was finding a few chomped on (and then they'd just drop it on the ground!!!) so I decided to protect my investment.

Just didn't have enough to go around......

They have chomped my asparagus, many times, in an area with high deer pressure. The only things that do not get eaten are things with thorns, roses, all manners of thistle, brambles, nettles seem to do well,
some small thorny trees (buckthorn I think). I am waiting for the border vegetation to grow, then fence and replant where asparagus has been killed (some of it is alive if stunted). I have also a bed next to my house with 20 asparagus, that goes untouched, but I think it is due to hostas and other tastier plants nearby, and the deer pressure at my house is low.
