June 6: Wildlife in the Garden

Learn how to attract desirable wildlife to your yard while discouraging and repelling species that like to feed on your plants. Dr. David Drake of the UW-Madison Wildlife Ecology Department will present an engaging look at wildlife in garden situations and also cover some local research projects and resources on urban wildlife.

June 13: Lawn care

Lawn Care: Dr. Doug Soldat of the UW-Madison Department of Soil Science will discuss various facets of lawn care, including learning about grass species, seed selection and sowing, watering, fertilizing, aerating and mowing. An activity based on selecting grass seed will follow the class.

June 20: Plant Processes and Pesticide Safety

The first talk will focus on processes such as photosynthesis, transpiration and how plant hormones can affect growth and
senescence. Learn about IPM (Integrated Pest Management) techniques and using pesticides safely should that step be necessary. We will also cover characteristics of organic, bioactive and traditional pesticides, avoiding weed and insect resistance using IRAC categories to rotate pesticide modes of action, understanding signal words that indicate pesticide toxicity, and more. An activity reading pesticide labels is included.

June 27: Invasive Species

This class will mostly consist of invasive plant ID and management by cultural and chemical means. Invasive plant species are non-native, able to out-compete native species in natural ecosystems such as woodlands, and have no natural enemies. This differentiates them from weeds that primarily invade disturbed areas like gardens and roadsides. We will review the DNR NR40 list of restricted and prohibited invasive species for Wisconsin and explain the categories of regulated plants. (Speaker Lisa Johnson)

July 11: Weeds and Weed Management

We will talk about using various techniques to manage weeds in the garden and landscape and spend some time reviewing a rogue’s gallery of common weeds, both grassy and broadleaf types. You will get an electronic copy of a handout that walks you through a taxonomic key for identifying grasses as well as other resources. We encourage you to send in photos of weeds from your yard ahead of time. An activity will be included. (Speaker Lisa Johnson)

July 18: Native plants & pollinators

This session will focus on groups of insect pollinators and how you can attract and support them by growing various native and nativar plants. We will also cover a number of recommended native plants for sun and shade and their growth and maintenance needs. A lab in the Teaching Garden will be included. (Speaker Lisa Johnson)

July 25: Disease Management in the Garden

Growing Healthy Plants: Basics In Plant Disease Management Brian Hudelson of the Plant Disease Diagnostics Clinic will present
information on common methods for disease control, their pros and cons, and how you can adapt these techniques for use in your own home garden. (Speaker Brian Hudelson). A lab session in the Teaching Garden will follow. Note that this class may run late due to the activity.

August 1: Perennials for Shade

Learn about how to select shade perennials for your garden as well as general care, propagation and maintenance. Find out about herbaceous perennial plants (native and non-native) that will thrive in light, medium and deep shade. We will also discuss plants that tolerate dry shade and wet shade. A lab in the Teaching Garden will follow the class. (Speaker Lisa Johnson)

August 8: Perennials for Sun

Learn about how to select perennials for your garden as well as general care, propagation and maintenance. We will discuss a wide variety of native and non-native species that will do well in full, hot sun in dry areas all the way to half-sun locations. A lab in the Teaching Garden will follow the class. (Speaker Lisa Johnson)

August 15: Garden Design

This session will feature principles of garden design, use of color, tips to think about and a design activity. Participants are encouraged to submit photos of landscapes they want to design at by 3 weeks ahead of the class, and a limited number will be featured in the session.

August 22: Annuals

Learn about growing healthy annuals for pots, windowboxes and bedding situations. We will cover species characteristics and selection, siting, growing in containers vs bedding situations, watering, and fertilizing. We will also address designing with annuals in-ground and in containers. A lab in the Teaching Garden will be included. (Speaker Lisa Johnson, TBA speaker)
