In case you haven't heard: there are places in the Amazonian Jungle called Devil's Gardens. The gardens are large swaths of land composed of almost entirely one single tree the Duroia hirsuta. This tree's roots have the ability to secrete growth inhibitors along side it's symbiotic relationship between this tree and the lemon ant, this tree is able to negate competition by killing them. There are other trees that create clonal colonies in which the colony grows new trunks from a root system underground.
So I am wondering: is it feasible that a tree could evolve to use its roots to search our other trees and grow a new clone through the trunk of its competitor? Which should split the competing tree in half and kill it all at the same time reproducing.
