The Green Thumb Gardening series will give you the practical knowledge to keep your home garden thriving! University of Wisconsin Extension educators and local horticulture experts will provide in-depth and accessible information for everyone from the novice to the experienced gardener. In 2020-2021, our class offerings have been expanded, including a Fall, Winter, Early Spring, Mid-summer and Late Summer series of classes.

For the safety of all participants, classes will be held online. Blended (in-person/online) classes may be available later in the year as conditions permit. Optional outdoor lab sessions for some classes in Spring (e.g. shrub pruning class) and Summer will be held in the Dane County Extension Teaching Garden . Separate registration for labs will be needed as space will be limited due to the need for social distancing. Facemasks will be required for these in-person events. Class registrations are open now.
