The Next Best Book Club discussion

I am looking for a book. I think the title is "Oil and Water Don't Mix" It is set in the Cumberland Mountains. There is a cottage with a witch. It's a Young Adult written in the 1970s or before. The main character is a young girl just moved to the mountains, who discovered the cottage and the witch. The witch has a beautiful garden with herbs. Anyone can help me remember?
