I'm in zone 5. The dormancy oil I was using forever is discontinued (Ortho Volck oil). Can someone who knows about rose care advise as to a product I can buy to replace Volck oil? Thank you.

Welcome!

Ortho's Volch Oil was 97% petroleum oil - if you want something similar, you will have to read the labels. Here is an article from Colorado State University that may give you better options:
