Car spring used as a spiral anchor sounds good.
What might help is a socket drive fitting welded or clamped to the sky-poin=
ting end of the spring.
Dig a hole with post hole digger ..... drop the spring in ..... fill with d=
irt ( and water ? ) and serve.
Removal would consist of reverse twisting the spring out of the ground.
