March can be such a finicky month! Two years ago there was a long warm spell, only to be followed by two nights with extremely cold temperatures which killed many plants, including many Hydrangeas, to the ground! Long range predictions are for average spring temperatures, but it never hurts to start the spring gardening chores early! Keep referring to notes of 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 actually yielded better results!
