Thank you for reporting this comment. Deer love tomato plants. And they can be very bold, they will walk right up next to the house and eat yew or rhododendron foundation plantings, as well as any tomato plants or other goodies they find. You need a high fence or some other deterrent to keep them out.
Anyhow you do not want to put bar soaps for deer control on the *ground*, cut the bars into halves or quarters and put atop stakes or hang from low tree branches (make little sachets for them out of old onion bags; you *can* just drill thru the soap and use a nail but it won't last as long).
