Is this a trick question ❓ 😂

Although i'd phrase it as peeing against a tree rather than on it; it obviously depends on the context, but just irt the tree itself, i'd say it is encouraged

It rhymes, so it's acceptable.

The question is acceptable for who

pee contains enough nutrients for plants to feed a person

Good fertilizer for a tree

why do you need a tree? ... just do not pee on yourself.

Who dares to ask?
