Pros and Cons of Interplanting Garlic with Fruit
In addition to borers Garlic helps ward off aphids, flea beetle, Japanese beetle, fungus gnats, codling moths, cabbage loopers, ants, snails and spider mites. There is also some proof that it deters mammalian herbivores such as rabbits and deer.
Grapes - While garlic will benefit the grapes in the area of pest and fungus suppression there is some evidence that planted too close to the grapes it may actually impede their growth. They can still be planted at a safe distance, I would just avoid having them so close that they are drinking out of the same trough.
Blueberries - Garlic grown near blueberries can benefit the blueberries in the area of pest and fugal suppression. It also helps condition the soil for the unusual requirements of blueberry plants.
Raspberries Benefit from being planted with garlic for the same reasons as other fruits, an added plus is that raspberries are preyed upon by Japanese Beetles which garlic helps to repel.
