Perhaps spurred by the recent spell of warm weather, there is a fair bit of activity outside in the garden already.  If you look outside, you may see that your garlic has started to appear.  The timing of emergence is dependent on the date that it was planted, so it is possible that yours is farther ahead or a bit behind ours, but in the garden here it started to emerge on Thursday night (I saw the first sprouts on Friday morning).  The rhubarb, chives and parsley have also started to push out some new growth!
