Have you explored the use of the black plastic netting fences? It is sold by Home Depot and TSC. I believe it is 6ft tall and fairly tough. Can’t break it pulling with your hands! It goes with the premise that deer can’t see it well, won’t jump into it because they CAN feel it when they walk into it, so they avoid the area. So letting deer learn where fencing is before planting, as they CALMLY explore what you are doing, should help prevent a stampede trying to use an old trail later. Blocking an established trail with some netting pieces might help establish a trail AWAY from your newly fenced garden areas.
We were out on a carriage driving picnic and saw net fencing being used for protection of a HUGE garden area for flowers. I presume the flowers were sold commercially, the beds were immense rows with a big variety of blooms. Maybe they had bouquets in every room of the very large house!! Ha ha There were a couple greenhouse looking buildings inside the fenced area too. The net fence was toghtly stretched on frames mounted to posts. No trees or brush around the fencing. Everything flowery inside the fence was quite lush, very colorfull, with no deer to eat or destroy things. That area, as well as most of Michigan, is way overpopulated with White Tail deer.
We could easily see thru the black netting to the flowers. The black framework holding netting was the most visible thing about the fences. I would not call it obtrusive though anything that keeps the deer out is good!! I have black fencing metal fencing to protect garden beds from the dogs and find it almost disappears looking at it. Flowers show thru much better than light color fence wire.
Until recently, they have not bothered my yard, but they now romp in both the neighbors front yard daily. Three dead deer hit by cars in my paddock roadside ditch. And a deer superhighway across the hayfield!! Not many deer hunters locally anymore. I have been considering the deer net fencing to keep them out I have caged and covered the rosebushes to protect them. Dogs keep them out of the fenced back yard.
Same #*^€ deer cross the horse fields regularly, sometimes get caught in the tensile wire by the antlers and pull it off the posts, maybe break a wire. They can really make a mess of several sections of wire!! No deer killed or found caught in the 8 strand fences. So we have to keep checking fences for damage, especially during their rut time.
