Shopping at the grocery store has its advantages and disadvantages. To avoid sprouting, opt for organic store-bought garlic, as homegrown varieties are more difficult to cultivate and may have been treated with fungicides or sprayed. Softneck garlic, which has a mild flavor, may be found at most supermarkets. There is a wide range of garlic seed/cloves to choose from at your local garden center, as well as a guarantee that it will sprout.
