How Trees Communicate Underground

Introduction

Trees are not solitary beings; they communicate with each other through complex underground networks. Using root systems and mycorrhizal fungi, trees share nutrients, warn of pests, and support weaker neighbors. This “wood wide web” is a fascinating aspect of forest ecology.

How Trees Use Underground Networks

1. Nutrient Sharing

Through mycorrhizal connections, trees can transfer nutrients to other trees in need, especially seedlings.

2. Chemical Signaling

Trees release chemical signals through roots to warn nearby trees of pest attacks, allowing neighbors to bolster their defenses.

3. Supporting Weaker Trees

Older or healthier trees can support weaker ones by funneling resources through the network.

Implications for Tree Care

Understanding these networks highlights the importance of preserving soil health and minimizing root disturbance.
