Gardening in March is a guessing game. Will it warm up and will it stay warm? Will the rains start and when will they let up? About the only sure thing is that March comes and March ends. That we can count on.
Without the heavy snowfalls of the past few years and with much warmer temperatures you can go ahead and push the envelope. Just be certain to keep something on hand to cover up your early spring plantings if the night-time temperatures drop below thirty degrees.
We are all tempted to take advantage of the warm days. Be prepared and remember that spring always gets the last word in the garden.
