Abstract: A device for controlling growth patterns of lower limbs of a tree or shrub is formed from a sheet of a flexible material having first and second edges such that deforming the sheet to place the first and second edges in contact produces a hollow, tapered device. The device has a first end opening and a second end opening that is larger than the first end opening. The sheet preferably has a plurality of elongate passages near the first end opening arranged to define a plurality of tapered end portions. A fastening device may be used for connecting portions of the first and second edges together such that the agricultural growth control device may be assembled around a tree trunk adjacent the lower limbs of the tree. A tying device fastened around the tapered end portions secures the agricultural growth control device to the tree.
