Bay Wise

Bay Wise Landscaping
Did you know that everyone in Maryland lives within half a mile of a stream, rivers, or storm drain that ultimately leads to the Chesapeake Bay?  The practices we use in maintaining our lawns and landscapes can affect the health of our local waterways and our environment.  Learn about the Maryland Bay-Wise Program along with gardening and landscaping practices anyone can implement in order to have a positive impact on the Chesapeake Bay. 

Who Polluted the Chesapeake?
In this activity, children of all ages participate in a 20-30 minute interactive story to learn how rivers become polluted over time as human populations have increased and land uses have changed. This example demonstrates that just as we each contribute to the problem, we can also each be part of the solution.

Grow It - Eat It

Vegetable Gardening Basics
This presentation covers a range of topics related to growing vegetables, including starting your first garden through advanced techniques and tips to extend the season, preventing and managing pests and diseases, growing food in containers, and get the most from your garden.  Speakers can easily tailor this presentation to thoroughly cover your group’s particular needs/interests.

Raised Bed Gardening
Why should gardeners install raised beds? This presentation shows the advantages of using raised beds for both the garden and the gardener.  Raised beds extend the growing season, bring order to the garden, and keep problems away from the vegetables. Explore the different types of materials to use to create raised beds, and get great ideas for your garden. Directions for building your own raised bed are also included.

Mother Nature’s Pharmacopeia
This presentation explores the history of pharmacology and the use of herbs as medicine both in the past and in the present. Truth be told, science has done much to validate what the ancients practiced all along. The everyday herbs we cook with are as healthful as they are tasty.

Herbs Native to North America
Herbs native to North America were (naturally!) used by Native Americans. Interestingly, while Europeans developed a strong culinary herb tradition, Native Americans primarily used herbs as medicine. This seminar explores the herbal legacy of North America, a landmass as rich as it is wide in useful plants. Full of lore and legacy, this chat is as entertaining as it is informative. And that ain’t no sassafras!
