Experts and BHG readers answer.
Deer "resistant' is not the same as deer "proof" as you're finding out. There are several methods to keep deer away -- Many people claim that using MIlorganite fertilzer repels deer. A fence, of course, will work (if it's tall enough). If you set up a hot wire, a deer usually only has to touch it once and they never come near again. A pet dog is good for chasing them away. And repellents like LIquid Fence are actually pretty effective, although prohibitively expensive for large gardens.
