Show overview
Completely Arbortrary has been publishing since 2020, and across the 6 years since has built a catalogue of 287 episodes, alongside 13 trailers or bonus episodes. That works out to roughly 320 hours of audio in total. Releases follow a weekly cadence.
Episodes typically run an hour to ninety minutes — most land between 1h 1m and 1h 16m — and the run-time is fairly consistent across the catalogue. The publisher flags most episodes as explicit, so expect adult themes or strong language throughout. It is catalogued as a EN-language Science show.
The show is actively publishing — the most recent episode landed 2 days ago, with 23 episodes already out so far this year.
From the publisher
Tree advocate Casey Clapp and his tree-curious friend Alex Crowson bring you a podcast about trees and other related topics. History, culture, art, religion, science... trees affect and are affected by everything. Join Casey and Alex on their silly and educational journey to prove it.
