I have lived on five acres in Lillian Alabama since 1990, surrounded by woods on all four sides and never had a problem with deer until this summer. They have always been here but stayed in the woods until we had the drought this summer, now there are at least four that show up day and night. They are eating the daylilies and have destroyed the winter garden. I have put deer fencing around the hybridizing area but the seedling area is to large and would be to much of a problem and expense to fence since I use a tractor with a tiller to rework the six sixty foot beds. My question is has anyone used the ultrasonic things that suppose to repel deer. They work like a dog whistle and cost about $60. Or any other suggestions that may help.
Update Jan 7 2018
I did buy three of the ultrasonic things after reading the reviews on several different types. They worked really well for about two months then had no effect on the deer. The only thing that worked was applying chicken litter (4-4-4) every two weeks. Now the seedling area is also fenced as of yesterday.
