Ask-a-Dave's-Gardener: What can I do to keep deer away, 1 by PhilS46

I live in Zone 7, SW Virginia rural area. We have a healthy deer population.
I have a 20 X 30 flower garden which was established 5-6 years ago.
When the local acorn crop is good the deer aren\'t as bad but that seems to have changed also.
I have tried Lowe\'s \"Deer Away\" and other stinky products that are supposed to keep deer / rabbits away but it seems to not work.
I started planting only \"Deer Resistant\" varieties of plants. I followed a Univ. of Michigan file, I found, which listed \"deer resistant plants\" sorted by most effective. My Knockout Roses used to be safe but the last two years they have been eaten down. The only plants they have not eaten are my butterfly bush, iris, red hot pokers and lavender bush. This year they ate my Stella D\'Oro\'s down to nothing. I could only plant those but it would be an uninteresting garden.
Sorry for the long rant but I am frustrated because I like gardening but don\'t like seeing the results of my labor go for nothing.

Can anyone with similar problems help me. Aside from chaining hunting dogs around my garden, when can I do ?

I posted a picture of my garden before the deer attack. Those knockout roses on the end, and Stella D\'Oro on the left have no blossoms on them at all now

Thank you

Phillip
