Ridding my yard of trumpet vine has been a multi year task. The roots are surprisingly deep and tearing up the yard was necessary. Even then, just small portions of root can sprout and spread quickly. Glyphosate application on new growth has to be done from spring through fall. The worst part is that i planted it to begin with, it took years to grow and bring flowers. By that time, I was just beginning to realize how invasive it was and it was already too late.
