Gardeners always look forward to spring;  buds are beginning to swell on the trees, early bulbs are beginning to poke their way out, and the lawn begins to turn green.  While spring may be the busiest and most exciting time of year for most gardeners, there are tasks that need to be done throughout the year, and there are even a few things that you can do in the winter to prepare yourself for the coming year.  Here is a Calendar of Garden Events for you to keep track of everything that needs to be done in your garden.
