If you want to freshen up your garden space and help others do the same, consider dividing perennials that you’ve had in your garden for three years or more. Perfect plants include coneflowers, phlox, day lilies and hostas. Novices or experienced gardeners are invited to trade their perennials (in pots or plastic bags) at this entertaining event. Come to the Maple Grove Community Center parking lot, near the skate park, rain or shine. Plants usually trade quickly, so don’t be late. 763.494.6535.
