Wendy Andresen will present part four of her garden demonstration, “Pruning and Shaping the Perennial Garden,” on Tuesday, Sept. 7 at noon at Merryspring Nature Center in Camden.

Labor Day is not the end of the gardening season! Andresen will continue her popular garden demonstration series with a presentation concerning autumn maintenance. Learn how to prepare plants for colder weather while coaxing autumn color from perennials. Participants need not have attended prior demonstrations in order to attend part four. Andresen’s demonstrations are based on techniques outlined in Tracy DiSabato-Aust’s classic garden reference book “The Well Tended Perennial Garden.” Copies of the book will be available for purchase.

Andresen and her husband, Ray, moved to Camden in 2006 from Connecticut, where they owned and managed a garden design and maintenance business. She 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.
