There is one huge downfall to using tires as raised beds (besides being really ugly and hard to mow around). The dirt gets baked if not replaced and tilled in the spring. Garlic is planted in the late summer. Today I dug over 200 heads of elephant garlic. Every garlic head had to be individually dug out of rock hard soil.

As long as I am showing off my deer proof garden here is my scarecrow: CPR Annie. She guards my raspberries, strawberries and blueberries. Well not really - though she has been known to give human visitors a start when they spot her. The dogs have not discovered that the berries are ripe. Once they do, lying beneath the bushes in the cool, damp sawdust is their favorite spot in the yard. They just need to lift their head for a sweet feast.
