At 2 p.m. Saturday, March 15, the Piedmont Master Gardeners will present “Pollinators for Four Seasons,” a free Garden Basics class. The program is open to all and will be held at Trinity Episcopal Church, 1118 Preston Avenue, Charlottesville. Master Gardeners will explain how all of us can help address the decline in pollinators and enjoy them year-round by providing them food and shelter in our garden spaces, whether we have a large rural landscape or an urban patio or balcony. Space is limited. To register and reserve a place in the class, visit https://piedmontmastergardeners.org/events/. Registration closes at 5 p.m. March 14 or when the class is full. Garden Basics is a partnership with the Bread and Roses ministry at Trinity Church.
