The point is that these people are renting a property. They obviously do not feel that they should respect the owner, neighbors or the land that they are renting. If someone chooses to plant gourds and pumpkins as part of their landscape plan, rock on with their bad selves. But, the homeowner, should be made aware of it as it can affect the curb appeal of the home or invite bugs, animals or some other kind of uninvited things into a neighborhood. That is just not smart in a neighboor hood as far as bad feelings, impact on home worth, or invasion of the property by varments.
