Do all villagers water flowers?

[Lotusblossom]

I want to put villagers that water plants next to the garden areas

From Nookipedia!

In New Horizons, villagers with the nature hobby can be seen walking around and watering multiple flowers. Other villagers can only water one flower at a time.

It might be worth putting villagers with the nature hobby closer to the garden areas

In addition to what SJ said, the Beautiful Town Ordinance also encourages villagers to water flowers.
