No sex or nudity.

A girl has a flashback of her and a boy kissing in the middle of the woods. Scene lasts 1-2 seconds. Nothing graphic is seen or heard.

It's a TV-14 rated horror series. About as graphic and intense as Stranger Things. This same rating goes for almost all of the CryptTV shows.

S1 E1: A girl sees 3 teens looking at a fourth dead teen that supposedly overdosed. The 3 teens tell the girl that if she blabs, they will hurt her father. Sounds worse then it actually is.

Throughout the series, Lanie and Evie use The Birch to kill everyone that has wronged them. (Pretty much Carrie with a tree monster.) We never see any of these deaths. We only see tree vines wrap around the victims and then the screen cuts to black. Note that the series is TV-14. Not a single episode is TV-MA as of yet, so nothing graphic is shown.

It's implied that teens take drugs.

A mom and dad provide their daughter with dope so that she will stop having nightmares.

In the final episode, a woman poisons a baby because the baby is evil. We do not see this.

The Birch is a giant tree monster. It will most-likely be scary to younger children.
