I think I've got snails in the garden, but I know the birds are visiting. Because I only caught a cardinal in there, I decided as a goodwill gesture that I would not scare him off. But there are about 8 baby tomatoes that I can only imagine look mighty tasty to him, so I started researching these 2 problems.
Here's the interesting advice on the intertubes:
1) Get something shiny
2) Get something that looks like it could hurt a bird
3) Snails are electrocuted by copper
And bizarrely enough, I had all those things in one masterful solution hanging in the TajMaShed.
