Wendy Andresen will present part three of her garden demonstration, Pruning and Shaping the Perennial Garden, on Tuesday, Aug. 3 at noon at Merryspring Nature Center in Camden.

Andresen’s demonstrations are based on the techniques outlined in Tracy DiSabato-Aust’s classic garden reference book “The Well Tended Perennial Garden.” Participants need not have attended prior demonstrations in order to attend part three. In this third part, participants will be able to see the results of earlier pruning and the effect it has on bloom time. In addition, participants will also learn how to clean out and cut back plants that are past their bloom, as well as have the opportunity to view the late summer color. Copies of DiSabato-Aust’s book will be available for purchase.

Wendy and her husband, Ray, moved to Camden in 2006 from Connecticut, where they owned and managed a garden design and maintenance business. Wendy currently serves as a volunteer at Merryspring, where she maintains the park’s perennial beds.

Merryspring members and all children attend talks free, and there is a charge of $5 for non-members. This is an outdoor demonstration and attendees should dress for the weather.

Merryspring is a member-supported nonprofit nature education center and park located at the end of Conway Road just off Route 1 by the Hannaford shopping plaza in Camden. For more information call Merryspring at 236-2239 or visit merryspring.org.
