In "The Continuous Vegetable Garden" Charlie Nardozzi applies lessons learned from ecologically-informed gardening to bring vegetable and fruit gardening into a new, more sustainable, and less laborious era.

James Hitchmough, an eminent British garden designer and former professor of horticultural ecology asserted on a previous episode that research confirms that gardens rich in alien plants support a greater diversity of insects. Today, Matthew Shepherd of the Xerces Society, an organization founded to promote insect and invertebrate conservation shares a different understanding of the science.

In this week's Growing Greener Heather McCargo, founder of the Wild Seed Project, describes its programs to encourage gardeners to grow native plants from wild-collected seeds to preserve genetic diversity in the garden and beyond, and how McCargo has embraced the evolution of her personal garden from meadow to biodiverse woodland.
-
One of the ways that invasive plants displace indigenous floras is "allelopathy." In a conversation first broadcast in February 2024, Dr. Susan Kalisz of the University of Tennessee Knoxville describes how many introduced plants actually poison the soil so that indigenous species cannot germinate or flourish in their former homes.

A square foot of topsoil typically hosts thousands of dormant seeds deposited by previous floras. Nathan Lambstrom of Lambstrom Garden Ecology discusses his research into how this "soil seed bank" can enhance or derail ecological restoration, and how to manage your "account" to benefit your garden.

Is your pruning aimed only at gratifying your aesthetics and needs? Chris Roddick also views pruning from the plants' perspective, promoting techniques that enhance their growth patterns and ecological function as well.
