To produce large bulbs, garlic needs a long growing season, so where possible plant cloves in autumn. If you live in a very cold area or your garden soil is too heavy, delay planting until the early spring or plant the cloves in modules in winter. Place the modules in a sheltered position outdoors to provide them with the necessary cold period. Plant them out after they have started to sprout in spring.
You can start to harvest your garlic when the foliage starts to die back. You can leave a few in the ground for a second season. Dry them thoroughly after lifting. Store bulbs in a cool, dry place, at 5-10 Celsius degrees (41-50 F), in bunches or plaits made with the dried leaves or place them loose on trays.
