I have a star jasmine in a large pot. It was an outdoor plant. Here in E. WA our winters are very cold, and in years past, when left outdoors, they froze. This one has become large and I would like to keep it alive through the winter. It is now in the garage. The vines have become very long, I would like for it to bush out more, but when do I prune it? Now, or spring?

Star Jasmine is hardy in zones 8-10 and you are in zone 6, so protecting it over the winter months is important. I'm concerned that there won't be enough natural light for your plant to survive the winter in your garage. Using a bank of fluorescent shop lights to supplement natural light will help your plant maintain its health until it can go back outside again. These plants are normally pruned in early spring, just as new growth begins. You can prune yours back now, but expect it to produce new growth, which will be cold-sensitive and may be spindly due to lack of natural sunlight. If you have a choice, wait until spring to prune it back.

Best wishes with your plant!
