I Xenocide visas att när den gamla Mothertreeen dog i en eld som startades av byborna efter att Quim dödades, "planterade de" den mest respekterade fruen för att odla en ny tegelträ.
In the middle of a clearing strewn with ash, Ender, Valentine, Miro, Ela, Quara, Ouanda, and Olhado all stood and watched as the most honored of the wives was flayed alive and planted in the ground, for her to grow into a new mothertree from the corpse of her second life. As she was dying, the surviving wives reached into a gap in the old mothertree and scooped out the bodies of the dead infants and little mothers who had lived there, and laid them on her bleeding body until they formed a mound. Within hours, her sapling would rise through their corpses and reach for sunlight.
Using their substance, she would grow quickly, until she had enough thickness and height to open up an aperture in her trunk. If she grew fast enough, if she opened herself soon enough, the few surviving babies clinging to the inside of the gaping cavity of the old dead mothertree could be transferred to the small new haven the new mothertree would offer them. If any of the surviving babies were little mothers, they would be carried to the surviving fathertrees, Human and Rooter, for mating. If new babies were conceived within their tiny bodies, then the forest that had known all the best and worst that human beings could do would survive.
