Vertical Mulching and Worms in Soil with Glynn Percival
Download MP3In this episode of The Urban Forestry Radio Show and Podcast we speak to Dr. Glynn Percival, Manager of Bartlett's Tree Research and Diagnostic Laboratory at the University of Reading, UK who has been using vertical mulching techniques to improve soil texture. His strategy is to drill holes into the soil that are 12 inches deep and 3 inches wide. He then fills the holes with a mixture of topsoil, compost, biochar. And he also puts worms into the holes and in various spots on the site and lets them do the rest of the work.
This month's recommended resource is a Silky Sugoi 360 Pruning Saw from Bartlett Tree Experts.
