A unitary device for securing the root ball of newly planted trees and/or shrubs into proper position, for stabilizing the trees and/or shrubs to prevent shifting or toppling while the tree and/or shrub root systems are first developing. The device includes a horizontal cross member, and a couple of prongs perpendicularly depending from the horizontal cross member, all formed from a single piece of rod or tubing material. At the time of planting, after the root ball of the tree is set into an appropriate hole and the tree is in proper position, the free ends of the prongs of the device are driven into the ground such that the outer prong is retained in the firm portion of the soil, and the inner prong engages the root ball. The outer prong is of a sufficient length to be held securely in the soil, and the inner prong is both arranged in position and sized in length to engage the root ball securely. The device is driven into the soil deep enough for the cross member to be recessed into the root ball to provide a firm engagement therebetween and to ensure that the device is established below the finished grade of the ground.
