Designing a garden for a small space is enough of a challenge. But once you have created one, how do you fend off the uninvited guests? Although insects, critters, fungi, and other plant diseases are part of gardening, there are ways to discourage the most destructive pests. Bring your questions to Mary Sullivan of the New England Wild Flower Society on Wednesday, March 8 at 7 pm, and let’s find a solution.

This class is part of the Urban Gardening Series, a set of classes designed to help city dwellers grow healthy, sustainable, and beautiful urban gardens. Led by Society staff in partnership with the Cambridge Conservation Commission, these free classes take place at the Cambridge Public Library (449 Broadway, Cambridge, MA).
