I planted my garlic at the end of October; pointed end up, in ridges in a raised bed.  Garlic needs some cold weather to begin with, to ensure that you get a good crop and, fortunately, we’ve had frost and snow this January.  I can already see some green shoots poking through the soil.  We buy our bulbs on line from The Really Garlicky Company and have found that we get large bulbs and a good harvest.
