Plants may not have mouths or ears, but they do communicate—with each other and even with insects! Through complex chemical signals, plants can warn neighbors about incoming pests, summon helpful insects, or even adjust their own defenses.
Some plants, like sagebrush, release airborne chemicals when attacked by herbivores, triggering nearby plants to bolster their own defenses. Underground, an entire “Wood Wide Web” of fungal networks allows trees to share nutrients and even "talk" across distances. Nature’s secret conversations are happening all around us—you just have to know how to listen!
