Garlic comes from the mountainous regions of Central Asia and has adapted to extreme changes in temperature, including very cold nights. As a result, garlic performs best when subjected to a cold period of one or two months. Ground temperatures of between 0 — 10º celsius encourages optimum clove formation, making it very suited to our Irish climate and Autumn planting often produces better crops than garlic sown in Spring. Garlic enjoys a long growing season, so if planted in October up to early December, the harvest usually occurs in July/August and the bulbs are much bigger.
