BONUS EPISODE: 80 Minutes with the Evergreen State's "Doctor Christmas Tree"

Feliks Banel's guest on this BONUS “O Tannenbaum” EPISODE of CASCADE OF HISTORY is Gary Chastagner, Professor Emeritus of Plant Pathology at Washington State University. He’s an award-winning and much honored academic scientist with the enviable nickname of "Dr. Christmas Tree." We spent almost an hour and a half on December 19, 2025 talking with Dr. Christmas Tree – aka Gary Chastagner - about his research, and about how you can take better care of your Christmas tree this year and every year, to keep it from drying out, and to keep the needles from falling off.
