Description
The biggest part of this week's podcast is a tour of Howard's art gallery, in preparation for an April 25, 2026 show and sale. The Dirt Doctor non-profit TORC (Texas Organic Research Center) has been supported for many years by the sale of Howard's art. Howard also answers questions about his research into the best formula to duplicate the weedkiller mix in Agralawn Crabgrass Killer, how and when to transplant yucca, and if horse manure is safe to use in the garden. In a related topic, he describes the easy test for herbicide contamination in compost (comes from manure in animals that ate hay with herbicide treatment), and wraps up with a discussion of the sick tree treatment and haint blue paint.
Find these subjects and more in this week's podcast.
