Gardening in a Changing Climate- Benefits & Challenges 

The climate in the Midwest is among the fastest changing in the world. In this class, we will discuss how these changing conditions have been slowly impacting the way we garden and grow our favorite plants. From plants that will soon disappear to ones that you never knew could ever grow here, Derek will show examples how weather trends are changing the way that Iowa gardens.

Vegetable Gardening Feeds the Body and the Mind

Gardeners can find fulfillment in producing food to eat and challenge their minds as they work towards solving garden problems throughout the season. We'll talk about vegetable gardening including site selection, soil health, planning, planting, transplanting, garden care and harvesting. Think of your garden as part of a larger ecosystem, and learn to grow with it.
