Today's topics: the bareroot season, low-chill apples, leaving the leaves, blooms in winter, and more.

We're featuring Louis Armstrong and Earl Hines tonight. We’ll hear Armstrong with Billie Holiday, Sy Oliver, and with his All Stars, as well as selections from Porgy & Bess with Ella Fitzgerald. Then we have Earl "Fatha" Hines in a live concert, some solo work, and with Johnny Hodges.

We have two main threads today: the chaos at Twitter since Elon Musk took over, including why the social platform matters, plus a conversation about social media and whether we’ll ever figure it out. Cindy Shen says we will. She’s a social media expert and professor of communication at the University of California, Davis, and points out that people have always figured out how to get a handle on disruptive technology -- including things we no longer view as technology, such as the printing press.

“Over time, as people become more accustomed to the technology, we don’t see technology as this causal agent," she says. "We realize that humans have agency as well. ... We have a say about how we want to use the technology, maybe to maximize its positive impact and minimize its harms.”

How do we get to this better place? Digital media literacy is a start.

On today's program: Winter flowers, including camellias and snapdragons and hellebores; compost and pesticide residues, and more.
