Different types of deer have different eating habits. What works for white tailed deer may not work for black tailed deer or mule deer. Mule deer can just lean on a fence and be into the garden. Elk do the same thing. If they want into the garden, they will make sure they get in ...
I have seen even black tailed deer tip toe through a rosemary patch .. deer are supposed to hate rosemary to get to a spot where they could leap into a garden. They knew where the roses were, so they were willing to put up with the rosemary.
Steve has a lot of good ideas. I don't know if the stones would stop the deer up here because that is normal up here.
It's their persistency that boggles my mind. The way the deer first got into my garden this winter was to jump over the trash cans down in the carport to a very small landing spot. Squeeze through between an almost vertical slope and a deer fence to a point where they could climb the slope and jump a three foot fence at the top of the slope.
AND there were plenty of unfenced species roses growing in the meadow across the road ..
Tulips, heucheras, hostas, roses and more are deer candy. Town deer will eat things that a normal self-respecting deer in the back country would never touch.
