A tree hydrating device for providing water to a live or cut tree. The tree hydrating device includes a pouch having an interior volume that can receive and store fluid. The lower end of the pouch includes an opening for connection to a flexible, elongated tube. A second end of the elongated tube is removably securable to a tap. The tap includes a stem for engaging the elongated tube and a threaded exterior so that it can be inserted into the trunk of a tree and securely positioned therein. Once the tap is inserted, a user can connect the second end of the tube to the tap so that fluid is provided from the pouch, through the elongated tube, and into the tree under the force of gravity. In this way, the tree is provided with constant hydration.
