I was wondering what people are using to control poplars, black poplars, etc on brushed land. We cleared a few hundred acres a couple years ago, floated it the following spring,and let the wild grass come. Its that type of land you don't wanna plow (God made the earth in 6 days then he threw rocks at this on day7). Most of the sucker trees are about 3 to 4 feet high,.
