Winter garden.

"January is the quietest month in the garden.  ...  But just because it looks quiet doesn't mean that nothing is happening.  The soil, open to the sky, absorbs the pure rainfall while microorganisms convert tilled-under fodder into usable nutrients for the next crop of plants.  The feasting earthworms tunnel along, aerating the soil and preparing it to welcome the seeds and bare roots to come."
