How to kill a young tree planted in front yard area

Question

A small tree was planted in my front yard by landscapers improperly. The bulb is in the ground, exposed with no mulch on it but dirt around it. How can I remove it because it is too close to a streetlight post. It is too heavy for my husband to lift out of the ground. Could I put a slit in the bulb in the ground and put Epson salt in the sack so it will die and become brittle?
