A tree cannot walk away from trouble…but it can adjust its posture.
The hidden “muscles” that trees use to do this have just been found. 💡
Researchers studying young poplars found that specialized “tension wood” can form on opposing sides of a stem, producing pulling forces that help straighten it. Think opposing muscles, but made of wood!
The discovery is not simply that trees respond to gravity, the research shows how their own shape influences where corrective growth happens.
