I know nothing about Sarr's. Here it goes; A friend who not really collects CP's just whatever's hardy in his area and he has some Sarr's and the deer will not leave them alone. So, he asked me but I haven't a clue. What should I tell him? He also has some Sundews that get eatin as well. How do you make them stop? I don't have deer in my area so I've never had deer eat anything, so I really have no idea.
