Tree anchoring apparatus has a plurality of interlocking anchor units with each anchor unit having connection means that allow the anchor unit to be secured to at least one adjacent anchor unit, an anchoring point provided for each anchor unit, and a cable or strap securable to at least one of the anchoring points. The plurality of interlocking anchor units are transportable disengaged from one another and can be interlocked with each other in situ to jointly provide a surface for supporting an overburden of soil. The cable or strap can be used to secure the interlocked anchor units to a root ball of a tree located there above.
