Oof that's hard to answer. I edit Wikipedia pages of botany-related topics so I'm usually reading stuff that's NOT 20-minute bites. I also have a particular interest in parts of nature that break the, imo, false dichotomy between "abiotic" and "biotic" (incl. aeroplankton, mycorrhizal fungal networks, aeonophiles, niche construction, soil ecological succession, etc)

Actually recently I've mostly been listening to lectures by some scientists I follow:

Evan Gora at the Cary Institute does research on big trees in tropical rainforests and recently published some fascinating work on tree adaptations to lightning strikes https://www.youtube.com/watch?v=KjGFWDSXtJk or https://yewtu.be/watch?v=KjGFWDSXtJk

I'm also a big fan of Suzanne Simard's research on "mother trees". She wrote a book I've yet to read called Finding the Mother Tree that also has an audiobook available. But she also regularly does talks

A book that kicked off the popular interest in mycorrhizae is The Hidden Life of Trees by Peter Wohlleben which is also quite digestible. RadioLab also had a great episode about it https://radiolab.org/podcast/from-tree-to-shining-tree

And here are some of my favorite publication that sometimes cover these topics:
