March in the Garden

March is a guessing game in the garden. About the only thing we can count on is that March too shall pass. So go ahead and push the envelope, but keep the row covers handy.

Everyone should have their seeds started, their trees and shrubs pruned and their tools ready to go. After that, the most important thing is to have patience.
