    Abstract: The grow pole is a hollow tube for growing multiple plants. The tube has vertical portals into which plants and their supporting medium are inserted. The tube has an end cap on its bottom end for supporting growth media disposed in the tube. Thus, the tube is at least partially filled with plant growing medium, such as dirt, and supporting structure or material to hold multiple plants and to permit watering through one end of the tube. If desired, a plant may be inserted in one end of the tube. Along its length, the tube includes multiple ventilation holes to provide oxygen to the roots.
