When you want to grow your own, it's important to buy garlic bulbs especially raised for planting. This quote is by Royal Horticultural Society 'Garlic is frequently used in Mediterranean and Asian cooking, so it’s hardly surprising it's become popular to grow at home. Garlic is simple to grow and you’ll get plenty of fat, juicy garlic bulbs, if you grow in a sunny site. Don’t be tempted to plant garlic cloves from the supermarket though, buy from a garden centre or mail order supplier.
