Teachers who are called gardeners may be more protective of flowers. What do you mean?

This means that teachers called gardeners will be more responsible to their students.

Teachers are a glorious and lofty profession, but not all teachers are good teachers, and not all teachers are very responsible for their students. Gardeners are usually used to describe hard-working and responsible people. If you describe a teacher, it usually means that the teacher is a good teacher who is serious and responsible to the students.
