Dreaming of wandering off and creating a garden, they instead stayed put, waiting for their husbands to share their vision.

But the male Ents, being notoriously contemptuous of 'hastiness' dithered and dathered, doing so for so long that the Entiwives became static and tree-like - literally bored stiff with their inaction.

Becoming "treeish" seems to be a process requiring a long period of time, so I don't see that happening on a large scale without at least some Ents being aware. I would also question the likelihood of the process happening to every one of the Entwives, since it seems to affect Ents fairly randomly, and not necessarily as an intentional act.
