i want to grow more "field grown" aka back yard/garden. however i find my on going war with weeds a loosing battle. As the trees get fed well so do the weeds, shading out lower branches on JBP. i layed down some weed cloth for air potted plants, but still fighting with weeds in air pots. how do you cut down on weeds. i only have 30 ish trees how do the bigger operations manage? im thinking of truly field growing more trees, but looking for weed solution. please advise.
