The weather makes for interesting conversation especially this year.  People have been reporting tulip leaves beginning to show, tree buds beginning to swell and the like.  I was pruning some trees and sap was running like it was April.  You, too, may have noticed you garlic cloves sprouting.  If you haven't already, I recommend covering them with a mulch such as straw to help keep the cloves from being pushed out of the ground by the thawing and freezing of the soil.  The sprouts may freeze but garlic is tough and has survived a lot more harsher conditions.  I admit, I get concerned too and have to remind myself it will survive.
