    Lecture: Even Better Soil! More advanced soil management for the desert gardener

    7:00 pm-8:30 pm

    Even Better Soil!  More Advanced Soil Management for the Desert Gardener

    Speaker – Master Composter Jim Lootens

    Good garden soil includes both dead organic matter and living organisms.  Jim will explain how composting creates this essential part of soil.  Understanding the ‘whats’ and ‘why’ makes the ‘hows’ easier.

    Thirty years ago Jim joined the Tucson Organic Garden Club and learned basic composting.  In 1992 he helped build the compost demonstration site at the Tucson Botanical Gardens.  That year he also helped teach two classes a month at TBG, adhering to a rather structured ‘how-to’ program.  Jim’s understanding of composting has evolved since then and is constantly changing.  He treats the act of composting as an art-form; flexible and dynamic.  Come learn from Jim’s years of experience of composting in the desert.
