Do Trees Talk to Each Other? Read our bi-monthly "Trees Matter" article for May-June to find out.
Yes, trees do "talk" to each other by sending out chemical signals to their neighbors. Potent chemical hormones are the messengers that convey different kinds of information about insect attack, water stress, and nutrient deficiency. These chemical messengers travel from tree to tree through a hidden underground, interconnected system of fungal tendrils. Trees also seem to prefer cooperation, not competition, when it comes to sharing crown space atop the forest canopy. Just look at the difference in tree shape when a tree grows solo in a field versus alongside many others in a forest.
