The GARDENA gardening expert
Dear Ms. V., we treat garlic in the garden just like normal onion sets. The only difference is that you plant garlic cloves not in March/April but in April/May, as the origins are generally sensitive to frost. No, you don't have to peel them. The garlic plant develops from the clove, and the typical bulb with its numerous cloves develops at its base. It is the smell and the root excretions from this bulbous plant which deters aphids & co.
