The Falling Leaves: Summer's Soft Farewell

A tree does not lose its leaves; it lets them go, on purpose, with a little goodbye built at each stem. This episode watches one leaf's whole descent.

The science, gently

  • In autumn, trees grow a special layer at each leaf's stem that gently lets the leaf go.
  • The reds and golds were in the leaf all summer, hidden under the green.
  • Fallen leaves feed the soil that will raise the spring's new ones.

Wonder together

  • What did you let go of this year that made room for something new?
  • Which is your favorite: the falling, the crunching, or the pile?
  • Where do you think the red hides all summer?

Tonight's calm-down

Be the leaf at the end of the branch, done with holding. Let go on an out-breath and take the long, unhurried zigzag down, side to side, to the soft ground of sleep.
