March can be such a finicky month! Several years ago, there was a long warm spell followed by two nights of extremely cold temperatures. The result was a multitude of Hydrangeas killed to the ground! Some years we see snow storm after snow storm, while some years it is merely rain. So far it has been a mild winter with a few cold snaps that may prove damaging to some early bloomers. Fingers crossed! Keep referring to your notes or diary from last year as to when you sowed seed and performed other chores as you need not reinvent the wheel. Also, keep making notes for this year so that you can see if any of the changes you made yield better results!
