60 - Wake Up Sleepy Trees!

60 - Wake Up Sleepy Trees!

In this episode, I explore one of nature’s most fascinating transitions: how trees survive winter and reawaken in spring. Trees don’t hibernate like animals. Instead, they enter a complex dormancy that helps them withstand extreme cold and conserve energy. Through internal hormones and external cues like sunlight and temperature, trees navigate the changing seasons with remarkable precision.

The Two Types of Dormancy: I talk about endodormancy, which is controlled by internal tree hormones, and ecodormancy, which responds to external weather patterns. These processes help prevent premature budding during a false spring.

How Trees Avoid Freezing: I share how trees create a natural antifreeze by increasing sugars and proteins. This protects their internal cells from ice damage—especially in species like sugar maples that can supercool to extreme temperatures.

Sap Flow and Spring Signals: As spring nears, sap starts flowing from the roots to the branches, awakening the buds. I discuss how this process not only brings leaves and flowers but also gives us maple syrup, which changes in flavor depending on the timing.

Watching the Signs of Change: From swelling buds and tree "sweating" to fungi regreening, I talk about the subtle signs you can look for in your local trees that signal spring has arrived.

Takeaways:
This episode is a celebration of patience, precision, and nature’s built-in wisdom. Trees teach us that timing matters—some changes need to come gradually, and not every warm day is an invitation to leap ahead. Whether it’s hormonal signals or temperature cues, nature has its way of balancing risk and readiness.

I encourage listeners to step outside and notice what’s changing right now. Are the buds swelling? Can you spot sap on a tree trunk? These are the first signs of trees "waking up"—and a reminder that rebirth and growth often begin quietly.
