What 80's horror flick was about a person who was connected to trees?

Question

I think the title had "guardian" in it somewhere. It was about this woman who was maybe a nanny, and she was connected to the trees. She even got a big cut on her thigh, and instead of a scab, tree bark grew over it.

Anyone remember this obscure movie?

Answer 1

The Guardian (1990)

Friendkin's horror film since the legendary 'The Exorcist' doesn't come close to that one's brilliancy, but it merely stands as an enjoyable waste of time. The Guardian is a rather anonymous horror entry with several macabre fairytale aspects. It's all about an all-American family that faces the ultimate nightmare: the loss of a harmless, innocent infant! A young couple just moved to Southern California when the wife is pregnant. They hire a seemly friendly nanny, but she turns out to be an evil tree-worshiper who sacrifices pure baby blood to an old tree.

Answer 2

It is "The Guardian" with Jenny Seagrove as the Nanny. (1990)
