OK, squirrels, you win.
After many battles, including several I mentioned here, I admit that the squirrels have won. I covered plants in chicken wire, moved them to a shepherd's pole far away from easily climbable structures, and cast voodoo spells on them (not really).

I don't know if I did anything differently last year to keep them away or if they're just more brazen, but I hate them. I hate the squirrels. Good thing my garden at Twig's house is doing well:
