I have alot of deer and they do not seem to touch my Kalmia. Having said that, I have alot that they DO like so that may be the deterrant. I spray with Liquid Fence, Deer Out, and several others, changing every now and then. They do not like and will not touch Pieris, Mahonia, Skimmia, Sarcococca, hellebore, ferns, pachysandra. I am starting to get rid of my hostas that are away from the house along with daylillies. I just can't sit back and watch another summer waking up to sticks instead of blooms! They are beautiful majestic animals>>>every county should have one.
