Saturday Mornings at the William Wolkoff Garden

Most Saturdays (and some days during the week) during the year our volunteers meet at 9:00 AM at the William Wolkoff Dahlia Garden in Bayard Cutting Arboretum.

Volunteers support the garden by preparing the tubers for planting, maintaining the garden during the bloom time, digging up the tubers at the end of season, and preparing them for storage. Each season provides a hands-on dahlia care learning experience, all are welcome.

Work in the garden is followed by coffee and snacks at 11:00 am. On Saturdays after coffee, any LIDS Member (new or old) can ask any Garden Associate who is still present any questions they may still have about Dahlias. Joe Lysik, our expert Garden Director, is also on hand during Wednesday & Saturday work detail to guide and teach everyone present about whatever we are doing that morning.
