I get so excited with the first sign of spring. New beginnings, the garden awakens, and new plantings emerge. When the soil is moist, its the best time to dig. Even if you may consider future plantings, dig when opportunity is ripe. It not only saves labor later, also water. I think amidst all the talk of drought, we should live in a constant state of water conservancy. Living in Las Vegas for many years made me pay attention to this precious commodity. So, winter usually being that time for prepping; spring can also be the time to consider switching out water hungry plants for more xeric options.
