Old dude, I sympathize.

My sister-in-law lives in a woodsy area of South Carolina where deer eat everything. She does grow gardenia bushes (right next to the house) and I believe she says deer don't eat hellebores. Hellebores are nice.

Back in Merry Old England, the rich figured out how to cope with deer. They built high brick walls around their gardens. Expensive, you bet.

And have you heard of the ha-ha? The ha-ha was a stone wall 8 feet high which kept deer from moving from the parklike estate grounds to gardens and terraces near the stately home. Again, mucho dinero, and no doubt dangerous to humans. And their deer were probably smaller than ours.

I put no faith in the urine idea. The deer can probably smell us and the places we've been gardening, quite well all the time.
