    7 Deadly Stems: PRIDE (Ohio Buckeye)

    Pride, the downfall of many an ancient Greek hero, is the subject of today’s Deadly Stem. As is the Ohio Buckeye (Aesculus glabra). How did this underwhelming tree become a regional icon?

    7 Deadly Stems: GREED (Russian-Olive)

    An oft-reviled tree, the Russian-olive (Elaeagnus angustifolia) is the quintissential greedy little bastard. Its invasiveness is infamous, and the disappointments it presents are seemingly endless. Then we answer a listener question about “Stumpy”!

    7 Deadly Stems: WRATH (Bullhorn Acacia)

    Are you sensitive? Do you show aggression when you're afraid or perceiving some sort of attack? Do you have a mercenary army of ants at your disposal to dispact at the first sign of aggression against you? Then you might just be a bullhorn acacia (Vachellia cornigera).

    7 Deadly Stems: GLUTTONY (Common Fig)

    7 Deadly Stems: GLUTTONY (Common Fig)

    The common fig (Ficus carica): one of humanity’s first food obsessions. From covering Adam’s junk to covering other Eve’s junk, this plant has no shortage of cultural import. But does it deserve the valor it’s flaunted for hundreds of years?

Scent strolls will now be even better

I just discovered this podcast and already LOVE IT!

I am an Aromatherapist and do a scent stroll in my local park which is also a Victorian cemetery ( part of the magnificent seven in London) and walk around the grounds and connect the conifer trees with their traditional, historical and benefits while smelling the essential oils and getting to know the trees.
Thank you for the fun way you pass on all the knowledge about the trees and make it easy and entertaining, I am
I am taking notes and will make sure to mention your podcast in my walks now for those who want to know more about the trees.

One of my favourite podcasts ever !!!

I heard Casey on the Ologies podcast and loved that episode so when he mentioned he had his own podcast I had to listen.
I love how interesting they make every tree sound and I especially love their seasonal episodes.
I recommend this podcast to anyone I can !!!!

Thank you Casey and Alex!

Hey guys,
I was late to the party and only stumbled across Completely Arbortrary last August. Two years before that, I moved back to the UK from Spain where I worked as a dive instructor and I moved to the centre of England and needed to find a new career and a new passion, I was stumped for a while and was feeling low, finding your podcast, hearing Casey’s enthusiasm for trees, and learning along with Alex gave me a new direction and a new found love. I went back to college the following month, studying forestry and Arboriculture at 27 and couldn’t be happier. You guys are a huge part of that happiness and I can’t recommend you podcast any more highly (having listened almost twice through already).
Keep inspiring people like me and your fungal associates will spearhead the fight against climate change! Or maybe just help a bit. But a win is a win! I honestly think of you both as friends who don’t know me, so thank you again!
Dan Ereira
