Yes. I had a rocky area in the back that nothing grows. I put them back there they bloomed they were beautiful for two years. Then I watched the deer back there all winter and in the Spring I saw they had ate every one that was in that garden.
I do not have a small nibble deer problem I have herds that come to my yard for breakfast lunch, dinner, Wedding Receptions, and all round Special Event restaurant. The 8' fence does not stop them. The fence was put in by the previous owner because there was an Olympic size swimming pool back there, which I promptly closed, but the 8' fence stayed.
