Trees share water and nutrients through the networks, and also use them to communicate. They send distress signals about drought and disease, for example, or insect attacks, and other trees alter their behavior when they receive these messages.” Scientists call these mycorrhizal networks.
So how do they do it? Plants communicate through their roots by secreting tiny amounts of special chemicals into the soil all through the plant's root zone - what scientists call the rhizosphere. These chemicals, called root exudates, send signals to every other living thing in the root zone.
These highly-connected hub trees, also known as Mother Trees, share their excess carbon and nitrogen through the mycorrhizal network with the understory seedlings, which can increase seedling survival. These Mother Trees in this way act as central hubs, communicating with the young seedlings around them.
Can trees hear?
It may not be 'hearing' in the conventional sense, as plants lack both brain and ears, but plants do have vibration-sensing receptors and so, at some level, could well be responding to sound.
They can also sense matter from the above ground parts of the plant that have been washed down by the rain into the ground. Above ground plants smell each other. If plants smell ethylene they know other plants are nearby.
Yes, trees talk to each other — although “talk” is not the right word. Talking requires a mouth, and trees don't have them. What trees do have, though, is the ability to communicate with each other. They do this in part via a fungal network that fills the spaces between them.
How intelligent are trees?
We can debate the definition of “intelligence,” but we know that trees can identify and solve problems in ways that we can't. They remember that spring is coming, and when it does they'll be ready to sense the weather and make their decisions in response.
“Intelligence is a loaded term,” but “plants are acutely aware of the world around them.” They can sense different kinds of light, evaluate chemicals in the air including those emitted by other plants, distinguish different kinds of touches to their leaves, and locate gravity.
