Garden Talk by Walter Andersen Nursery Podcast

Ken and George interview guest Susan Frazee discussing her experience with worm composting (vermicomposting) and her book, Martin Snell and His Worm Hotel. Frazee began her journey with a single tower-style bin, but quickly expanded three bins, including two DIY setups, as she collected more food scraps. Feeding the Worms: Red composting worms are remarkably "forgiving" and particularly enjoy treats like pumpkins and watermelon. Frazee noted that a single bin could be filled just by the remains of Halloween jack-o'-lanterns. Frazee used the nutrient-rich worm castings (manure) to support her neighbor's thriving garden of vegetables, citrus, and exotic fruits like passion fruit and figs. She also gave worms away to friends and neighbors to help them start their own composting systems. Worm Population Growth: In ideal conditions—like the temperate climate of San Diego—worm populations can double every two to three months. Starting with 200 worms can lead to a massive population by the end of a year. Research and Inspiration: To deepen her knowledge, Frazee conducted extensive research, ranging from Google searches to studying scientific publications and international composting initiatives in  Beyond her own backyard, Frazee envisioned worm composting as a potential fundraising opportunity for local schools.

In this episode of Garden Talk from Walter Anderson Nursery, Ken Anderson and George Allman answer listener questions and dig into two timely topics for Southern California gardeners: the eucalyptus leaf beetle problem (including why large trees often require professional, systemic treatment) and a practical “top vines” list for covering fences, trellises, and pergolas. You’ll hear tips and cautions on popular choices like star jasmine, mandevilla/dipladenia, creeping fig, bougainvillea, passion vines, and trumpet vines—plus what to consider before planting vigorous climbers.
