Landscape architect and gardener Carol A. Krawczyk of Kennett Square has published a beautiful wall calendar, "The Garden Calendar for Southeastern Pennsylvania 2018."
Carol describes the calendar as "filled with monthly gardening tips, full color photos of plants in bloom during each month, and gardening suggestions in the actual calendar. The actual calendar part includes red letter days (deadlines), green planting/harvesting dates, and blue to-do chores in the garden."
You can buy a copy at RP Nurseries in Willowdale; the State & Union shop in Kennett Square; the Gateway Garden Center in Hockessin; and online at eBay. Carol has also created a Facebook page for the calendar if you want more information.
