Hi, this is my first year growing garlic. I have a nice small bed of hardneck varieties that made it nicley through the winter and are about 8 inches tall. We are getting a late winter storm tonight with 6 to 8 inches of snow expected and about 29 degree weather. Should I run out and add a bunch of straw mulch, it has some around the base but everything has grown up through it. Thanks for any suggestions!
