Right about now, gardeners all over the northern hemisphere are getting the itch to go outside and get dirty. I know I am. Once the frozen earth has thawed enough, it will be safe to start putting our potted plants outside for a few hours at a time. Them and we will enjoy sitting on the stoop feeling the warm sun and air on our faces. But there are still two feet of snow on the ground, in some places. So, finding dirt can be a little difficult, much less playing in it.
