Years ago when we moved to CT (where the state flower is the rock), we had planted (I had to dig into this rock infested dirt), 25 rose bushes.
When the bushes started to bud, a herd of deer came by and had dinner.
My DW was LIVID! We went to the local nursery and asked how to get these deer out of our garden. I noticed that the nursery actually had an area that they had fencing and netting. I couldn't see netting the whole front of my house, so we kept on asking ... the owner and son offered to sit in our front yard, if they could keep the meat. I veto'ed plan b also.
Then he finally said that he had heard that deer avoid 'human noises' and that someone had turned on a radio to a talk show and the deer stopped coming around. I tried it and it WORKED! My son was a little unhappy because his window was right below the garage window where I put the radio every night. But a low volumed talk show did the trick.
