The invention relates to a method for installing subterranean supports for structures such as poles, posts and the like, and an apparatus therefor, which will permit such structures to stand free of any stays or guy wires and their associated anchors. The system comprises a support and an instrument for the installation of the support. The support preferably includes an upper and a lower collar assembly, each comprising a collar and a plurality of ground engageable blades pivotally connected thereto. In general, the collar assemblies are lowered into a hole in the ground and the installation instrument is utilized to extend the blades of the collars in a generally radial direction, causing the blades to penetrate the walls of the hole and thus securing the support therein.
