This week's interview is a discussion with Rainmaker.Earth representative Kevin Hauschel, their VP of Sales and Business Development in North America.

The biggest part of this week's podcast is a discussion of the Dirt Doctor's "cheat sheet," a multi-page list of the items he was asked about most often on the radio show. The list was there for quick lookup in case he forgot some detail, and it has grown over the years, old things removed, new techniques and products added. Howard also touched on his visit to this year's EarthX conference in downtown Dallas, and plans to air future interviews from there. Find these subjects and more in this week's podcast.

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.
