You can add Bamboo to the list of foliage that they can work with.
Had bamboo that got out of control over the last 11 years at my house. Wanted to shape it into a 6 foot hedge, and to get rid of some that was to close to my A/C and house electrical wires. Chuck stated that this was the first time that he would tackle bamboo. Never would have guessed that, Chuck and his two man crew did a fantastic job of cutting and shaping the bamboo, and cleaning up the cuttings and hauling it away. I will use them annually to keep my bamboo in check, and will also include my Japanese ornamental trees to be pruned and shaped.
