Dig Hole for Willow Oak (Initial Attempt)

What happens here

The presenter attempts to dig a hole for the willow oak tree using old, worn-out post-hole diggers. He struggles significantly due to the extremely hard, rocky soil, which he attributes to the previous daikon radish cover crop being ineffective in loosening it. He decides to either find a better spot or acquire new tools.

Goal: Dig a suitable hole for the willow oak tree despite hard ground.
